AB  - Aim of this work was to determine influence of current density on the roughness of the
electrodeposited zinc coatings. Electrodeposition carried out from two same solutions containing
different brightening additives. Furfural (in solution I) and dextrin (in solution II) were used as
additives. Influences of the thickness of the coatings on the surface roughness depending of the
current density and time of deposition and effect of the added additives on the structure of the coatings
were also studied.
Electrodeposition of the zinc coatings was done galvanostatically at current densities of 1, 2 and 4 A
dm-2. Times of electrodeposition were 10, 20 and 30 minutes. Pure zinc was used as anode, and steel
with unknown composition was used as cathode. All experiments were done at room temperature,
baths volume were 500 cm3.
Obtained results show that zinc coatings obtained from solution II have lower roughness than those
deposited from solution I. Current density and thickness of the coatings does not have large influence
on the roughness. The roughness values are from 0.41 μm to 1.219 μm (solution I) and from 0.316
μm to 0.812 μm (solution II). Current efficiency in solution I is 92.98-94.55% and in solution II 91.5-
96.91%. Coatings from solution II have better structure compared to coatings obtained from solution
I, so it can be concluded that dextrin is better brightening additive than furfural in used sulphate
baths.

AB  - This article is concerned with synthesis and characterization of electroconductive composite materials prepared by hot molding of mixtures of PMMA and electrochemically deposited copper powder and investigation of the influence of particle morphology on conductivity and percolation threshold of obtained composites and thermal characteristics. Electrodeposited copper powder content was varied from 0.5-8.8 vol%. Analysis of the most significant properties of individual components and prepared composites AFM and TGA analysis. The significant increase of the electrical conductivity can be observed as the copper powder content reaches the percolation threshold at 2.98 vol%. In the investigated range of electrodeposited copper powder concentrations the increase of the electrical conductivity of composites is as much as sixteen orders of magnitude.

Zapreminski udeli metalnog punioca su varirani u opsegu od 0.5-29.8% (v/v), a uzorci su pripremljeni hladnim presovanjem i izlivanjem u kalup. Karakterizacija je uključivala ispitivanje uticaja veličine čestica i morfologije na provodnost i perkolacioni prag kompozita koristeći različite tehnike ispitivanja: SEM, TGA, AFM. Termalna analiza pripremljenih kompozita je pokazala poboljšanje termičkih svojstava kompozita u odnosu na čiste polimere. Ovo poboljšanje se javlja usled prisustva metalnog punioca, koji je jako dobar termički provodnik, te se toplota emitovana tokom TGA merenja prvenstveno akumulira u puniocu, pa tek onda u polimernoj matrici, bila ona LC ili PMMA. Prisustvo trodimenzionalnih provodnih puteva je takođe potvrđeno.

Volume fractions of metal fillers in composite materials and tested samples were varied in the range of 0.5-29.8% (v/v), and the samples were prepared by compression and molding. Characterization included examination of the conductivity and percolation threshold of the composites using a variety of testing techniques: SEM, TGA, AFM. Thermal analysis of the prepared composites showed the improvement of the thermal characteristics of the composites. This was due to the presence of the metallic fillers, which are very good thermal conductors, hence accumulating the heat emitted during TGA measurements primary to matrix, whether it was lignocellulosic or PMMA. presence of three dimensional conductive pathways was confirmed.

Merenja su izvedena gravimetrijskom metodom i elektrohemijskim metodama (Tafelovom metodom ekstrapolacije i spektroskopijom elektrohemijske impedanse). Najveće dostignute vrednosti zaštitnog faktora ekstrakta žalfije su 60,04% u rastvoru 3%NaCl + 1 g/dm3 i 53% u rastvoru 3%NaCl + 1,5 g/dm3 u vremenskom intervalu od 6 sati. Međutim, isti rastvori u vremenskom intervalu od 4 i 24 h deluju katalitički na proces korozije bakra, te se ekstrakt žalfije ne može preporučiti kao inhibitor korozije bakra u 3%NaCl. Rezultati dobijeni spektroskopijom elektrohemijske impedanse i rezultati dobijeni sa snimljenih Tafelovih polarizacionih dijagrama potvrđuju rezultate dobijene gravimetrijskom metodom, te se mogu preporučiti kao vrlo pouzdane metode za brza koroziona ispitivanja.

In this paper, research on copper protection by processing corrosive environment while applying different concentrations of sage extract of 0.5g/dm3,1 g/dm3 i 1.5g/dm3 as green inhibitor in 3% NaCl solution was performed. Measurements were carried out by gravimetric method and electrochemical methods (Tafel extrapolation method and electrochemical impedance spectroscopy). The greatest protective values of sage extract of 60,04% were reached in 3%NaCl + 1 g/dm3 solution and 53% 3%NaCl + 1,5 g/dm3 solution in 6 hours interval. However, the same solutions act catalytically on copper corrosion process during time interval from 4 to 24 hours, that is why sage extract can not be recommended as inhibitor of copper corrosion in 3%NaCl. The results obtained by electrochemical impedance spectroscopy and recorded Tafel polarization diagrams, confirm results attained by gravimetric method, thus can be recommended as very reliable methods for quick corrosion tests.

AB  - The potentiostatic method and the theory of 'topochemical reactions' in the kinetics of the active dissolution and passivation process of AISI 420 stainless steel were studied. It was found that, to a great extent, the number of conversion steps is depended on the imposed potential. The experimentally obtained results were partially explained using Okamoto's theory of passivation.
AB  - Ispitivana je potenciostatska metoda i teorija 'topohemijskih reakcija' u kinetici aktivnih procesa rastvaranja i pasivacije AISI 420 nerđajućeg čelika. Pokazano je da, u velikoj meri, broj stepena konverzije zavisi od primenjenog potencijala. Eksperimentalno dobijeni rezultati su delimično objašnjeni Okamotovom teorijom pasivacije.

AB  - The inhibitive behaviour of Vitamin C, as a type of green inhibitor, on the corrosive behaviour of stainless-steel (SS) X4Cr13 within an aqueous solution of hydrochloric acid (HCl) was studied at concentration of c= (0.01, 0.1 and 1.0) mol L-1. Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS), was used for the measurements at 25 degrees C. To observe the morphology and microstructures of sample surfaces, after the electrochemical measurements a Scanning electron microscopy (SEM) was used. On the basis of the EDAX analysis within the solution of hydrochloric acid (0.01 mol L-1) with addition of Vitamin-C (0.005 mol L-1) the presence of the feri-chelates on the metal surface could be confirmed. The polarization curves revealed that the studied mixtures of the chosen inhibitor represented mixed-type of the inhibitor. The results show that the inhibition efficiency increases with the increase of the inhibitor concentration. This valid especially in the case of the lowest concentration of HCl (c= 0.01 mol L-1). In addition to this at higher HCl concentration (c= 1.0 mol L-1) the immersion time has a noticeable influence on the inhibitive response. Furthermore, the results obtained in this study showed that the inhibitory effect of Vitamin-C to a great extent on electrode potential.
