AB  - Nd:YAG laser was used for cleaning surfaces of cultural heritage iron artefacts covered with
corrosion products. The corrosion products were removed without damaging the base material.
Three different electrochemical techniques were used for the determination of the corrosion rate of
mechanically prepared iron, laser-cleaned iron and laser-cleaned iron with Paraloid B44 coating.
The morphology of the tested surfaces was analysed by SEM. The linear polarization resistance
technique, electrochemical impedance spectroscopy and linear sweep voltammetry have shown
that the corrosion rate of the laser-cleaned iron is approximately 50 % higher than the corrosion
rate of the mechanically prepared iron. Electrochemical impedance spectroscopy has shown that
the pore resistance of the Paraloid coating on the laser-cleaned iron sample decreases at the
beginning of the test and remains approximately constant after this period. At the beginning of the
test, the charge transfer resistance value is constant and then decreases rapidly i.e. the corrosion
rate of the iron in the Paraloid coating pores increases with time. During the linear sweep
voltammetry test of the iron sample with Paraloid coating, it was noticed that the anodic
polarisation curve shows an unusual shape at the potentials more positive than - 0.5 V
AB  - U ovom radu, Nd:YAG laser je korišćen za čišćenje površina artefakata od gvožđa koji su bili prekriveni korozionim produktima. Korozioni produkti su uklonjeni bez oštećivanja osnovnog materijala. Za određivanje brzine korozije mehanički čišćene površine, laserski čišćene površine i laserski čišćene površine na koju je nakon čišćenja nanesen zaštitni sloj Paraloid B44, korišćene su tri različite elektrohemijske metode. Morfologija čišćenih površina je ispitivana SEM mikroskopijom. Metoda linearne polarizacione otpornosti, elektrohemijska impedansna spektroskopija i voltametrija sa linearnom promenom potencijala pokazale su da je brzina korozije laserski čišćene površine uzorka od gvožđa za oko 50% veća od brzine korozije mehanički čišćene površine. Elektrohemijska impedansna spektroskopija je pokazala da otpornost pora Paraloid prevlake na laserski čišćenoj površini uzorka opada na početku ispitivanja nakon čega dostiže konstantnu vrednost. Na početku ispitivanja, vrednost otpornosti razmeni elektrona je konstantna nakon čega naglo opada, tj. brzina korozije gvožđa u porama Paraloid prevlake raste sa vremenom. Tokom ispitivanja tehnikom voltametrije sa linearnom promenom potencijala na uzorku od gvožđa sa Paraloid prevlakom, zapaženo je da anodna kriva polarizacije ima neuobičajen oblik pri potencijalima pozitivnijim od - 0.5 V

AB  - The paper analyses the corrosion behaviour of both naturally and artificially aged AA2024 aluminium alloy in NaCl solution in the presence of the corrosion inhibitor benzotriazole (BTA). The differences between these two aging tempers in terms of resistance to general corrosion are explained as well as the differences in terms of pit formation and pit growth. Based on the values of the polarisation resistance and the corrosion current density, the general corrosion resistance of the alloy is determined in the absence and in the presence of BTA. The resistance to pit formation and pit growth is determined on the basis of the polarisation measurements results. Scanning electron microscopy confirmed the expected differences in the appearance and size of the pits formed in naturally aged and artificially aged alloy. In the presence of the corrosion inhibitor BTA, for both aging tempers of the alloy, the corrosion resistance is significantly higher compared to the resistance in the solution without the inhibitor. The value of the polarisation resistance for both aging tempers increases over time. However, at the same time, the value of the constant phase element increases as well. An explanation for this phenomenon is provided. The calculated average value of the thickness of the adsorbed inhibitor layer on the surface of the aluminium alloy is in accordance with the inhibitor protective ability for both aging tempers.

AB  - The corrosion behaviours of naturally aged and artificially aged AA2024 aluminium alloys in 0.5 mol/dm3 NaCl solution in the presence of environmentally friendly corrosion inhibitors of 10 mmol/dm3 CeCl3, 10 mmol/dm3 BTA and the inhibitor mixture (5 mmol/dm3 CeCl3 + 5 mmol/dm3 BTA) were analyzed. The goal of this work was to determine the level of the synergistic effect of the inhibitor mixture and to explain the nature of this effect. Corrosion properties of the inhibitor layer were studied using the electrochemical impedance spectroscopy (EIS), while the resistance to pit formation and pit growth was studied by applying potentiodynamic polarisation tests. The results of scanning electron microscopy (SEM/EDS) showed that the size of pits formed in naturally aged aluminium alloy was smaller than that formed in artificially aged alloy. The synergistic effect of the inhibitor mixture on corrosion properties of naturally aged alloy was observed throughout 96 h, and in later phases of testing of artificially aged alloy. The synergistic effect of the inhibitor mixture was not noticed on pit formation and pit growth.

AB  - This study considers the corrosion behavior of the X5CrNi18 10 stainless steel‐welded joint in NaCl solution, with and without the presence of several corrosion inhibitors (NaNO3 , Ce(NO3)3, and CeCl3). The degree of sensitization of the welded joint to intergranular corrosion is determined using the electrochemical potentio kinetic reactivation method with a double‐loop method. Pitting corrosion tests are performed by the potentiodynamic method. Resistance to general corrosion and the stability of the passive film is assessed based on the results of electrochemical impedance spectroscopy measurements, as well as on the values of the corrosion and passivation current. The main goal of this study is to determine the relation of the welded joint microstructure to general and pitting corrosion in the presence of the corrosion inhibitors. The value of pitting potential for the base metal and weld metal in the presence of the NaNO3 or Ce(NO3)3 inhibitor is shifted to potentials in the transpassive area. The pitting potential for the heat‐affected zone also possesses a noticeable higher value. However, nitrate ions do not increase the general corrosion resistance of any part of the welded joint. CeCl3 does not increase resistance to general or pitting corrosion.

AB  - Metal matrix composites are very inhomogeneous materials, and their properties depend on various parameters (production process, constituents, their interfaces, etc.). The influence of SiC microparticles (40 mu m) reinforcement and graphite macroparticles (200-800 mu m) addition on the mechanical properties of Al-Si A356 alloy, produced by compocasting, has been assessed using macro- and nanoscale measurements of hardness and modulus of elasticity. The Al makes over 90 wt% of the A356 alloy, so the nanoscale measurements were performed on different alpha phase regions on each material (core of alpha phase, eutectic alpha phase, and alpha phase near the phase boundaries alpha phase/secondary phases). The results showed that there is no direct correlation between mechanical properties on macro- and nanoscale. The nanoscale results also showed that the secondary phases (SiC and graphite particles) can have significant effect on the mechanical properties on the atomic level, i.e. in the alpha phase regions very close to the secondary phases.

AB  - The corrosion inhibiting possibility examination of extracts obtained from fruits of rose hip and
horse chestnut was investigated. Rose hip extracted at different temperatures exhibited different
corrosion inhibiting effect. Rose hip obtained at 40oC did not show any inhibiting effect in neutral
pH medium, while in acidic media it expressed moderate protective impact (up to 55%) for steel
and mild corrosion inhibiting impact for zinc (39%), while for aluminium and copper it did not
have any inhibiting effect. Rose hip obtained at 25oC exhibited significant inhibiting effect for steel
(up to 62 %) and even better for zinc (up to 72%) in neutral media. For aluminium and copper
neither of Rose hip extracts showed any inhibiting effect. The Horse chestnut extract exhibits
moderate to significant inhibiting effect for steel (up to 55%) and zinc (up to 60%) in neutral
media. In addition to this, because of the complex chemical composition of these fruit extracts,
some further electrochemical investigation is suggested, aimed to determine a single component
inhibitive effect. Firstly, as one of prevailing components, tannins are examined. Linear
polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS) were used as a
testing techniques.

AB  - Nd:YAG laser was used for cleaning surfaces of cultural heritage iron artefacts covered with corrosion products. The corrosion products were removed without damaging the base material. Three different electrochemical techniques were used for the determination of the corrosion rate of mechanically prepared iron, laser-cleaned iron and laser-cleaned iron with Paraloid B44 coating. The morphology of the tested surfaces was analysed by SEM. The linear polarization resistance technique, electrochemical impedance spectroscopy and linear sweep voltammetry have shown that the corrosion rate of the laser-cleaned iron is approximately 50 % higher than the corrosion rate of the mechanically prepared iron. Electrochemical impedance spectroscopy has shown that the pore resistance of the Paraloid coating on the laser-cleaned iron sample decreases at the beginning of the test and remains approximately constant after this period. At the beginning of the test, the charge transfer resistance value is constant and then decreases rapidly i.e. the corrosion rate of the iron in the Paraloid coating pores increases with time. During the linear sweep voltammetry test of the iron sample with Paraloid coating, it was noticed that the anodic polarisation curve shows an unusual shape at the potentials more positive than - 0.5 V.

AB  - The influence of welding parameters on the resistance to pitting corrosion in welded joints of X5CrNi18-10 stainless steel was studied. Welding was performed by a TIG procedure in a shielding gas containing different amounts of nitrogen. The welding speed, the deposition rate of the filler wire, and the shielding gas flow rate were constant, which allowed the nitrogen content in the weld metal to be directly dependent on the nitrogen content in the shielding gas. It was shown that welding current and arc energy had a significantly lower influence on the resistance to pit formation and pit growth, than the nitrogen content in the shielding gas. Pitting corrosion testing was conducted using the potentiodynamic polarization method. The resistance to pit formation increases with the increase in nitrogen content in the weld metal, while the resistance to pit growth decreases. The microstructure of the weld metal becomes more homogeneous in the presence of nitrogen and the distribution of chromium more uniform, which leads to the increased resistance to pit formation. Also, due to the formation of ammonia ions, the pH value of the solution within the pit is higher than in the bulk solution, which also increases the resistance to pit formation.

AB  - The influence of SiC microparticles reinforcement and graphite macroparticles addition on the friction and wear characteristics of A356 Al-Si alloys, produced by compocasting, has been assessed using a pin-on-disc tribometer. The incorporation of SiC reinforcement increased the coefficient of friction and reduced the wear. The addition of graphite did not reduce the coefficient of friction. In the case of hybrid composite with 1 wt% graphite, wear was more or less the same as with SiC reinforced composite, while in the case of hybrid composite with 3 wt% graphite, wear was further reduced. On the worn surfaces of hybrid composites, the presence of the discontinuous mixed surface layer, containing graphite and transferred counter-body material, was noticed.

AB  - This paper considers the influence of nitrogen in the shielding gas during TIG welding as well as the influence of a welding current level on the resistance to pitting corrosion and intergranular corrosion in welded joints of X5CrNi18-10 stainless steel. Testing of pitting corrosion was carried out using the potentiodynamic method, while intergranular corrosion was tested with the Double-Loop Electrochemical Potentiokinetic Reactivation method. Pitting corrosion resistance of welded joints (the weld metal and the heat affected zone) is higher in the presence of nitrogen in the shielding gas, while integranular corrosion resistance remains unchanged. Pitting corrosion resistance of the heat affected zone in the welded joint formed in nitrogen-free shielding gas is lower than in the base metal, while the weld metal has similar pitting corrosion resistance as the base metal. With an increase in a welding current level, pitting corrosion resistance and resistance to intergranular corrosion of welded joints decrease. The passivation current density is shown to be a good indicator of pitting corrosion resistance of welded joints. Hardness values of the weld metal and the heat affected zone are slightly lower than the base metal hardness value.

AB  - Metal matrix nanocomposites (MMnCs) comprise a metal matrix filled with nanosized reinforcements with physical and mechanical properties that are very different from those of the matrix. In ZA-27 alloy-based nanocomposites, the metal matrix provides ductility and toughness, while usually used ceramic reinforcements give high strength and hardness. Tested ZA-27 alloy-based nanocomposites, reinforced with different types (SiC and Al2O3), amounts (0.2 wt.%, 0.3 wt.%, and 0.5 wt.%) and sizes (25 nm, 50 nm, and 100 nm) of nanoparticles were produced through the compocasting process with mechanical alloying pre-processing (ball milling). It was previously shown that the presence of nanoparticles in ZA-27 alloy-based nanocomposites led to the formation of a finer structure in the nanocomposites matrix and an improvement in the basic mechanical properties (hardness and compressive yield strength) through the enhanced dislocation density strengthening mechanism. Solid particle erosive wear testing demonstrated that these improvements were followed with an increase in the erosive wear resistance of tested nanocomposites, as well. Additionally, by analyzing the influences of type, amount, and size of nanoparticles on the erosive wear resistance of nanocomposites, it was demonstrated that there is an optimal amount of nanoparticles, which in our case is 0.3 wt.%, and that the presence of SiC nanoparticles and smaller nanoparticles in nanocomposites had more beneficial influence on erosive wear resistance.

AB  - The resistance to corrosion of the series of zinc-aluminum casting alloys modified with silicon and
strontium was studied in a sodium chloride solution. It was shown that general corrosion was the
main form of corrosion of Zn25Al-Si-Sr alloys in the test solution. The corrosion process takes
place through the anodic dissolution of the alloys, while the cathodic reaction is controlled by
diffusion of oxygen in the test solution. Three different electrochemical techniques were applied to
determine the corrosion current density, which is the electrochemical indicator of corrosion rate.
The value of corrosion current density for each Zn25Al-Si-Sr alloy was calculated using the value
of polarization resistance, obtained by electrochemical impedance spectroscopy or by linear
polarization resistance technique. The value of corrosion current density was also determined
directly from Tafel plots, which were recorded by linear sweep voltammetry. As the content of
silicon and strontium in the tested alloys increases, the value of corrosion current density
increases gradually. The results obtained by different electrochemical techniques are in good

abstract = "The resistance to corrosion of the series of zinc-aluminum casting alloys modified with silicon and
strontium was studied in a sodium chloride solution. It was shown that general corrosion was the
main form of corrosion of Zn25Al-Si-Sr alloys in the test solution. The corrosion process takes
place through the anodic dissolution of the alloys, while the cathodic reaction is controlled by
diffusion of oxygen in the test solution. Three different electrochemical techniques were applied to
determine the corrosion current density, which is the electrochemical indicator of corrosion rate.
The value of corrosion current density for each Zn25Al-Si-Sr alloy was calculated using the value
of polarization resistance, obtained by electrochemical impedance spectroscopy or by linear
polarization resistance technique. The value of corrosion current density was also determined
directly from Tafel plots, which were recorded by linear sweep voltammetry. As the content of
silicon and strontium in the tested alloys increases, the value of corrosion current density
increases gradually. The results obtained by different electrochemical techniques are in good
agreement, Otpornost na koroziju serije legura cink-aluminijum za livenje, koje su modifikovane silicijumom i stroncijumom, ispitana je u rastvoru natrijum hlorida.

AB  - Particulate nanocomposites with the base of ZA27 alloy were synthesized using an innovative route, which includes mechanical milling and compocasting. Scrap from the matrix alloy and ceramic nanoreinforcements were mechanically milled using the ball-milling technique, which led to the formation of composite microparticles. The use of these particles in the compocasting process provided better wettability of ceramic nanoreinforcements in the semi-solid metal matrix, which resulted in a relatively good dispersion of the nanoreinforcements in nanocomposite castings. The presence of nanoreinforcements led to the grain refinement in the matrix of nanocomposites. The mechanical properties of the synthesized nanocomposites are improved and compared with the properties of the metal matrix. The observed increase in the hardness of nanocomposites with Al2O3 nanoreinforcements (20–30 nm) was 6.5% to 10.8%, while the yield strength of these nanocomposites has increased by 12.2% to 23.2%. The hardness and compressive yield strength of the nanocomposites with Al2O3 nanoparticles (100 nm) increased by 1.7% to 8.0% and 2.3% to 8.3%, respectively. The increase in hardness of the nanocomposites with SiC nanoparticles (50 nm) was 11.5% to 20.6%, while the increase in the yield strength was 15.6% to 24.5%. The greatest contribution to the overall strengthening in the synthesized nanocomposites is the result of increased dislocation density due to the difference in coefficients of thermal expansion for the matrix alloy and nanoreinforcements.

AB  - Different types of weapons and military equipment, made of brass, are often exposed to extreme atmospheric conditions, to chemical agents, erosion and wear. It is important to evaluate the corrosion characteristics of brass in different corrosive environments, and especially after laser cleaning of corrosion products, various deposits and other undesirable surface layers. The brass corrosion resistance changes, after surface laser cleaning, were examined in this paper. Nd:YAG laser with lambda=1064 nm was used for laser cleaning process. SEM analysis was applied for investigation of the brass surface micro-morphology before and after laser cleaning. Electrochemical techniques such as linear polarization resistance, electrochemical impedance spectroscopy, linear sweep voltammetry and electrochemical frequency modification were used to study the corrosion characteristics of laser treated and mechanically prepared brass surface. The results of electrochemical tests have shown that the corrosion rate of laser treated brass surface is approximately same as the corrosion rate of brass surface prepared by the standard grinding and degreasing process. This indicates that the brass surface was efficiently cleaned by laser treatment with applied operating parameters without lowering its corrosion resistance. The abilities of different electrochemical methods for determination of corrosion rate were compared.

AB  - The resistance of X5CrNi18-10 stainless steel to pitting corrosion in a solution containing chlorides and sulphates was tested using the potentiodynamic polarization method. The obtained results show that the stainless steel is significantly resistant to pit formation, but it is susceptible to pit growth and crevice corrosion. Pits formed at the corrosion potential grow continuously. Statistical analysis of the results obtained during pitting corrosion testing was performed. It can be assumed with a probability of 95% that values of indicators of resistance to pit formation (the pitting potential Epit, the metastable pitting potential Empit and the difference Epit-Ekor) will be within the range of several percents. Values of indicators of resistance to pit growth (the amount of charge required for the pit growth q, the protective potential Eprot and the difference Epit-Eprot) will be within the broader range. In addition, the appearance of pits on the surface of the stainless steel, as well as the appearance of the pits bottom, were analyzed. It was shown that the structure of the stainless steel tested was not sensitized to pitting and intergranular corrosion, which means that the stainless steel was not previously thermally treated.

AB  - This paper describes the correlation between the value of the corrosion potential and various types of corrosion of metals and alloys and their welded joints. It is shown that using the method of electrochemical noise is possible to predict the tendency of metals and alloys and their welded joints to different forms of localized corrosion (e.g. pitting corrosion), on the basis of the corrosion potential value. Also, there is a correlation between the value of corrosion potential and the tendency of aluminum alloys to stress corrosion cracking. The correlation between the value of the corrosion potential and the type of corrosion inhibitor is presented. In addition, the correlation between corrosion potential and tendency of stainless steels to pitting corrosion, as well as the tendency of surgical implants to galvanic corrosion was considered. Criteria for sacrificial and active cathodic protection are based on the measurements of corrosion potential. Also, the corrosion behaviour of steel armature in concrete depends on the value of corrosion potential. The susceptibility of metal (steel) constructions and their welded joints to hydrogen embrittlement depends to a considerable extent on the corrosion potential of steel in the given corrosion environment. Due to a large number of applications of corrosion potential measurements, this study is divided into two parts (Part I and Part II).

AB  - The resistance to pitting and intergranular corrosion of the welded joint of X5CrNi18-10 austenitic stainless steel is analyzed in this paper. The resistance of the welded joint to intergranular corrosion does not depend on the nitrogen content in the shielding gas. It depends on the heat input into the welded joint, that is, on the welding current intensity. The resistance to pitting corrosion depends on the content of nitrogen in the shielding gas and on the welding current intensity. With the increase in the nitrogen content in the shielding gas, the resistance of the heat affected zone (HAZ) to pitting corrosion increases. The welding current intensity (heat input into the welded joint) shows two opposite effects. On the one hand, the increase of the heat input into the welded joint causes a more intensive precipitation of chromium carbides along the grain boundaries, which then leads to depletion in chromium of the grain boundary areas. The sensitization degree of the HAZ is thus increased and the formation of pits easier. On the other hand, with the increase in the welding current intensity, diffusion of nitrogen from the weld metal into the HAZ is facilitated, which contributes to the increased HAZ resistance to pitting corrosion. Possible mechanisms for increasing the HAZ resistance to pitting corrosion in the presence of nitrogen are also considered.

AB  - Nanocomposites were synthesized via compocasting using Zn25Al3Si and Zn25Al3Si0.03Sr alloys as the matrices and nanoparticles of Al2O3 (1 wt%) as the reinforcement. Structure of the nanocomposites was examined, and their basic mechanical and tribological properties were tested. Distribution of primary silicon particles in the structure of nanocomposites has been improved compared to their distribution in the Zn25Al3Si matrix alloy due to the presence of Al2O3 nanoparticles and strontium. The primary silicon particles in the structure of the nanocomposites were found to be more fine-grained compared to the same particles in the structure of the as-cast Zn25Al3Si alloy. Tested mechanical properties of the nanocomposite with Zn25Al3Si alloy matrix are improved, compared to the matrix alloy. The nanocomposite with Zn25Al3Si0.03Sr alloy matrix is characterized with slightly higher value of compressive yield strength and a slightly lower hardness value compared to the as-cast Zn25Al3Si alloy. Both nanocomposites showed lower wear rate and higher coefficient of friction, compared to the matrix alloy, in sliding under the boundary lubricating regime. However, the nanocomposite with Zn25Al3Si alloy matrix showed better tribological properties than the nanocomposite with Zn25Al3Si0.03Sr alloy matrix.

AB  - Corrosion behavior of metalized layers, obtained by Plasma Transferred Arc (PTA) process and by High-Velocity Oxygen Fuel (HVOF) process with the purpose to improve the wear resistance of vital parts of ventilation mill in a thermal power plant, has been tested. The test is performed using three electrochemical techniques, in a solution containing chloride and sulfate ions. It is shown that the steel surface (base metal) dissolves uniformly, without pitting or other forms of local dissolution. Morphology of metalized layers surface indicates that dissolution is non-uniform, but it still can be considered as general corrosion. The corrosion rate of base metal and metalized layer obtained by PTA process is rather low, while the corrosion rate of the metalized layer obtained by HVOF process is much higher. Also, the difference in corrosion potentials between the base metal and the HVOF layer is pretty high but slightly less than maximum allowed difference (prescribed by the standard), to avoid excessive galvanic corrosion. The values of corrosion rate obtained by different electrochemical techniques are in excellent agreement.

AB  - The effect of welding current on the pitting corrosion resistance in the welded joint of austenitic stainless steel X5CrNi18-10 was tested. Welding was carried out using three different current intensity (110 A, 130 A and 150 A). Testing of pitting corrosion resistance was performed by electrochemical potentiodynamic method on the base metal, in the heat affected zone (HAZ) and in the weld metal. Values of pitting corrosion resistance indicators for the base metal are similar to values of the indicators for the weld metal, regardless of the applied welding current. The values of indicators for pitting corrosion resistance in the HAZ are less than the values of these indicators for the base metal and for the weld metal. This is caused by the precipitation of chromium carbides at grain boundaries and by partial formation of chromium depleted areas along the grain boundaries in the HAZ. HAZ that was formed at welding current of 150 A shows the smallest pitting corrosion resistance. This can be explained by the largest depletion in chromium of grain boundary areas at welding current of 150 A. The sensitization degree in the HAZ to intergranular corrosion is also the greatest, in this case. With increase of the sensitization degree to intergranular corrosion the value of metastable pitting potential linearly decreases, which means that pitting corrosion resistance in the HAZ is reduced.

Zavarivanje austenitnog nerđajućeg čelika je izvršeno primenom tri različite jačine struje (110 A, 130 A i 150 A). Ispitivanja otpornosti prema piting koroziji su izvršena elektrohemijskom potenciodinamičkom metodom na osnovnom metalu, u zoni uticaja toplote (ZUT) i u metalu šava zavarenog spoja. Vrednosti pokazatelja piting korozije za osnovni metal su bliske vrednostima odgovarajućih pokazatelja za metal šava, nezavisno od primenjene jačine struje pri zavarivanju. Vrednosti pokazatelja piting korozije u ZUT-u su manje od vrednosti odgovarajućih pokazatelja za osnovni metal i metal šava. To je posledica delimičnog izdvajanja hrom-karbida po granicama zrna i obrazovanja hromom osiromašenih oblasti uz granicu zrna u ZUT-u. ZUT formiran pri jačini struje zavarivanja od 150 A pokazuje najmanju otpornost prema piting koroziji, što se može objasniti najvećim osiromašenjem prigraničnih oblasti zrna hromom pri ovoj jačini struje zavarivanja. Tada je i sklonost ZUT-a prema interkristalnoj koroziji najveća. Povećanjem stepena senzibilizacije ZUT-a prema interkristalnoj koroziji vrednost potencijala metastabilnog pitinga se linearno smanjuje, što znači da se smanjuje otpornost ZUT-a prema piting koroziji.

AB  - Susceptibility to intergranular corrosion in welded joints of austenitic stainless steel X5Cr-Ni18-10 was tested. The welding was performed with different intensity of welding current (110 A, 130 A and 150 A). The tests were performed using electrochemical potentiokinetic reactivation method with double loop (DL EPR method) on the base metal and in the heat affected zone. The results obtained by the DL EPR method show that the heat affected zone formed by welding with 150 A has the highest susceptibility to intergranular corrosion. The susceptibility to intergranular corrosion is considerably lower when applying smaller welding current. The base metal is resistant to intergranular corrosion. The indicator of susceptibility to intergranular corrosion (Qr/Qp)GBA is ~ 6 times higher for the heat affected zone (at 150 A welding current intensity) than for the base metal. Obtained testing results show that the welding current intensity greatly influences the susceptibility to intergranular corrosion in welded joints of stainless steel X5Cr-Ni18-10.

AB  - After sterilization of meat cans in a factory of meat and meat products in Serbia, occurence of corrosion on the can lids was observed. Sterilization of cans is usually performed in the presence of corrosion inhibitors. The protective ability of commercial corrosion inhibitor P3 and corrosion inhibitor benzotriazole (BTA) in a solution of NaCl was examined in this work, using electrochemical impedance spectroscopy and recording the polarization curves. It is shown that in the presence of the above corrosion inhibitors, resistance of the electrolyte in the pores of an organic coating, which was applied to a can lid, increases several times, which indicates an improvement in barrier properties of the organic coating. In the presence of corrosion inhibitor P3, the corrosion rate of a metal in pores of the applied organic coating is about ten times lower, while in the presence of corrosion inhibitor BTA the corrosion rate is three to four times lower. Corrosion inhibitor P3 slows down anodic reaction in the corrosion process, more than cathodic reaction, unlike corrosion inhibitor BTA, which slows down cathodic reaction. Based on tests performed in this work, application of corrosion inhibitor P3 (in concentrations 0.6 to 1.0 g dm-3) is recommended during sterilization of meat cans in industry of meat and meat products.
AB  - Posle sterilizacije konzervi u jednoj fabrici mesa i mesnih prerađevina u Srbiji, uočena je pojava korozije na poklopcima konzervi. Sterilizacija konzervi se obično izvodi u prisustvu inhibitora korozije. U ovom radu ispitana je zaštitna sposobnost komercijalnog inhibitora korozije P3 i inhibitora korozije benzotriazola (BTA) u rastvoru NaCl, primenom elektrohemijske impedansne spektroskopije i snimanjem polarizacionih krivih. Pokazano je da se u prisustvu navedenih inhibitora korozije otpor elektrolita u porama organske prevlake, koja je nanešena na poklopac konzervi, povećava nekoliko puta, što ukazuje da je došlo do poboljšanja barijernih osobina organske prevlake. U prisustvu inhibitora korozije P3 brzina korozije metala u porama organske prevlake manja je približno deset puta, dok je u prisustvu inhibitora korozije BTA brzina korozije manja tri do četiri puta. Inhibitor korozije P3 više usporava anodnu reakciju procesa korozije nego katodnu reakciju, za razliku od inhibitora korozije BTA koji više usporava katodnu reakciju. Na osnovu izvršenih ispitivanja u radu, može se preporučiti da se tokom sterilizacije konzervi u industriji mesa i mesnih prerađevina koristi inhibitor korozije P3, koncentracije od 0,6 do 1,0 g dm-3.

AB  - This paper briefly describes the relationship between corrosion potential and different corrosion forms of metals and their welded joints. The nature of corrosion potential and the method of its measurement is also described. It is shown in a simple way how the tendency of welded joints to galvanic corrosion can be determined on the basis of the meausred corrosion potential value. It is also shown that different metallurgical and corrosion states of aluminim alloys can be evaluated using the measured value of corrosion potential. The tendency to intergranular corrosion in the welded joints of stainless steels can be predicted on the basis of corrosion potential. Due to a large number of corrosion potential measurement applications this work is divided into two parts (part I and part II).
AB  - U ovom radu opisana je veza između korozionog potencijala i različitih vidova korozije metala i njihovih zavarenih spojeva. Pored toga, opisana je priroda korozionog potencijala i postupak njegovog merenja.Na jednostavan način pokazano je kako se na osnovu vrednosti korozionog potencijala može odrediti sklonost zavarenih spojeva aluminijumskih legura i zavarenih spojeva ugljeničnih čelika prema galvanskoj koroziji. Takođe je pokazano kako sena osnovu merenja korozionog potencijala mogu odrediti različita metalurška i koroziona stanja aluminijumskih legura, kao i sklonost zavarenih spojeva nerđajućih čelika prema interkristalnoj koroziji. Zbog velikog broja primena merenja korozionog potencijala, rad je podeljen na dva dela (deo I i deo II).

AB  - Corrosion behaviour of steel Sa 387 Gr. 91 is tested in solutions containing chloride and sulphate anions. These solutions simulate the conditions of marine and industrial atmosphere. The tests are carried out in a slightly acidic and moderately acidic environment. It is shown that the steel corrodes uniformly without pitting or other forms of local dissolution. Corrosion current density is determined by three independent electrochemical techniques (linear polarization resistance, electrochemical impedance spectroscopy and linear sweep voltammetry). Values of corrosion rate are calculated based on values of corrosion current density. Values of corrosion rate obtained by different electrochemical techniques are in a very good agreement. An estimation of the working life of a pressure vessel made of steel Sa 387 Gr. 91 is given from the standpoint of general (uniform) corrosion.
