AB  - This paper evaluated the inhibitory effect of Ce‐chloride and Na‐lactate
mixture on the AA2024 aluminum alloy in 0.1M NaCl solution. Electrochemical
impedance spectroscopy (EIS) was applied for testing the general
corrosion resistance, while potentiodynamic polarization measurement was
applied for determining the alloy pitting corrosion resistance in NaCl and
inhibitive solutions. The presence of cerium on the cathodic intermetallic
particles was confirmed by scanning electron microscope/energy‐dispersive
X‐ray spectroscopy analysis. The mixture of Ce‐chloride and Na‐lactate was a
more effective corrosion inhibitor than Ce‐chloride alone. The inhibitors
mixture is a mixed‐type corrosion inhibitor with a higher influence on slowing
down the cathodic reaction of oxygen reduction. The adsorption of the
inhibitor, the presence of cerium in different oxidation states (Ce3+ and Ce4+),
and lactate anion (C–C/C–H, C–OH, C═O, and O–C═O group) were confirmed
by X‐ray photoelectron spectroscopy analysis. A mechanism of inhibitor
adsorption on the surface of AA2024 alloy in NaCl solution was proposed.

AB  - This paper examined the degree of sensitization (DOS) to intergranular corrosion (IGC) and the level of electrical conductivity of the welded and non-welded AISI 304 stainless steel to obtain a suitable correlation. The DOS was determined by the double loop electrochemical potentiokinetic reactivation method (DL EPR), while the level of electrical conductivity was measured using a commercial device (non-destructive method). After electrochemical etching in oxalic acid, the microstructure of the specimen surface was analyzed by scanning electron microscopy (SEM). At DOS greater than ~ 0.5%, a clear linear dependence between the electrical conductivity and the value of the DOS was obtained, while there was a higher deviation from linearity for lower DOS values. The mentioned correlations were discussed in the sense of the precipitation kinetics of the Cr-carbide and the formation of Cr-depleted areas of different levels near the grain boundaries. Cr-depleted areas during anodic polarization measurements show lower resistance to pit formation. The presence of Cr-depleted areas in the vicinity of grain boundaries and the reduction of carbon content in the austenite crystal lattice increases the electrical conductivity of the stainless steel.

AB  - In this work, a tetrafunctional epoxy resin entitled 2,3,4,5-tetraglycidyloxy pentanal (TGP) was tested and investigated as a potential corrosion inhibitor for mild steel (MS) in 0.5 M H2SO4 solution. The corrosion inhibition process for mild steel was employed alongside various techniques, such as potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), temperature effect (TE), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and theoretical approaches (DFT, MC, RDF and MD). Further, the corrosion efficacies obtained at the optimum concentration (10−3 M of the TGP) were 85.5% (EIS) and 88.6% (PDP), respectively. The PDP results indicated that the TGP tetrafunctional epoxy resin acted the same as an anodic inhibitor type in 0.5 M H2SO4 solution. SEM and EDS analyses found that the protective layer formed on the MS electrode surface in the presence of TGP could prevent the attack of the sulfur ions. The DFT calculation provided more information regarding the reactivity, geometric properties and the active centers of the corrosion inhibitory efficiency of the tested epoxy resin. RDF, MC and MD simulations showed that the investigated inhibitory resin have a maximum inhibition efficiency in 0.5 M H2SO4 solution.

AB  - The synergistic effect of neodymium chloride and cysteine in NaCl solution was investigated. The concentration ratio of these two inhibitors was 1:3 (neodymium: cysteine). The corrosion resistance of AA7075 alloy was tested electrochemically using electrochemical impedance spectroscopy (EIS). Significantly higher polarization resistance in inhibitor-containing solution, along with phase angle peak shift to more negative values, indicate good corrosion inhibition by Nd-cysteine. The morphology, analyzed by scanning electron microscopy (SEM/EDS), showed that the surface of the AA7075 alloy was wholly protected from corrosion after 24h in NaCl solution.

AB  - The aim of this study was to investigate environmentally-friendly corrosion inhibitors based on the cerium-cysteine and their effect on 7xxx series aluminum alloy. The cysteine and cerium-cysteine complex structures were analyzed by Fourier-Transform Infrared spectroscopy (FTIR). The structure of cerium-cysteine was additionally determined using Nuclear Magnetic Resonance (NMR) and Elemental Analysis. Inhibitors efficiency was analyzed with Electrochemical Impedance Spectroscopy (EIS) and Potentiodynamic polarization techniques in 0.1M NaCl at room temperature, while Scanning Electron Microscopy analyzed the surface appearance and microstructure of the tested aluminum alloy with Energy Dispersive Spectroscopy (SEM / EDS) and Optical Microscope (OM). Different amounts of cysteine were examined in order to find an optimal concentration of inhibitor. The adsorption of the inhibitors followed the Langmuir isotherm, and based on the EIS results and calculated thermodynamic potential (Gibbs free energy), cysteine and cerium-cysteine proved to be good inhibitors for tested aluminum alloy. The optimal cysteine concentration of 0.06 mM as a corrosion inhibitor of 7xxx series aluminum alloy was determined. EIS diagrams confirmed that cysteine showed better inhibition than Ce-Cys complex.

AB  - The inhibitory effect of cysteine in the presence of selected lanthanide chlorides (LaCl3, NdCl3, and CeCl3) in a neutral 0.1M NaCl solution was analyzed. The cysteine concentration of 0.3mMwas determined as an optimal one. The resistance to general and pitting corrosion of AA7075‐T6 alloy in inhibitive solutions was determined using electrochemical impedance spectroscopy and potentiodynamic polarization measurements. The surface appearance of the aluminum alloy was determined before and after corrosion tests using scanning electron microscopy/energy dispersive spectroscopy, while the presence of an inhibitory layer on the alloy surface was confirmed by X‐ray photoelectron spectroscopy analysis and atomic force microscopy. The inhibitory effect of cysteine was significantly higher in the presence of all tested lanthanide chlorides, especially to pitting corrosion. The protective ability of cysteine was increased by lanthanides in the following sequence: Ln<Nd <Ce ions. The inhibitory effect of cysteine in the presence of cerium ions was examined in more detail as cerium ions provided the highest inhibitory effect, both to general and pitting corrosion.

AB  - In this work new green corrosion inhibitors based on the synthesized cerium-cysteine complex on AA7049 aluminum alloy were analyzed and compared to the mixture of CeCl3 and cysteine in 0.1 M NaCl. The complex structures were confirmed by FTIR, NMR and Elemental Analysis. It was shown that cerium was present in two oxidation states, CeIII and CeIV, when the mixture was analyzed, while there was only a CeIV oxidation state in the cerium-cysteine complex. The mechanisms of inhibitory action of the joint effect of CeCl3 and cysteine vs. their complex were proposed and analyzed in more detail.

AB  - The aim of this study is development and characterization of the novel Zn-Mn/Al2O3 composite coatings. The coatings 
were electrodeposited with constant current density on steel, from chloride solution, without any commercial additives. The 
Zn−Mn alloy coatings that show high corrosion resistance, may be used in future as an alternative to cadmium coatings. 
However, the pure Zn and Zn alloy coatings are characterized with poor mechanical properties. Therefore, in this work the 
alumina particles were incorporated into the Zn-Mn matrix, and the hardness and corrosion resistance of the obtained 
composite coatings were tested. The mechanical and ultrasound agitation were used to achieve good dispersion of plating 
solution and homogeneous co-deposition of second phase. The goal was to examine the effect of the agitation type in bath, 
on the attributes of the deposited composite coatings. The incorporation of Al2O3 particles was enhanced when the 
mechanical agitation of the solution was applied. However, in case that this agitation method was used, the agglomeration of 
the alumina particles occurred. In contrast, when an ultrasonic agitation of the plating solution was applied, the uniform 
distribution of the alumina particles could be achieved. The presence of particles in the matrix, along with applied 
ultrasound, resulted in grain refinement and homogeneous microstructure. The Al2O3 nanoparticles incorporated in Zn-Mn 
alloy matrix, resulted in a significant increment in the indentation hardness and a modest increase in the coating corrosion 
resistance. However, the coating hardness increased with alumina addition, only in case when an ultrasonic agitation of the 
electrodeposition solution was used.

AB  - Electrodeposition and characterization of novel ceria-doped Zn-Co composite coatings was
the main goal of this research. Electrodeposited composite coatings were compared to pure Zn-Co
coatings obtained under the same conditions. The effect of two ceria sources, powder and home-made sol, on the morphology and corrosion resistance of the composite coatings was determined. During the electrodeposition process the plating solution was successfully agitated in an ultrasound bath. The source of the particles was found to influence the stability and dispersity of plating solutions. The application of ceria sol resulted in an increase of the ceria content in the resulting coating and favored the refinement from cauliflower-like morphology (Zn-Co) to uniform and compact corallike structure (Zn-Co-CeO2 sol). The corrosion resistance of the composite coatings was enhanced compared to bare Zn-Co as evidenced by electrochemical impedance spectroscopy and scanning Kelvin probe results. Zn-Co doped with ceria particles originating from ceria sol exhibited superior corrosion resistance compared to Zn-Co-CeO2 (powder) coatings. The self-healing rate of artificial defect was calculated based on measured Volta potential difference for which Zn-Co-CeO2 (sol) coatings exhibited a self-healing rate of 73.28% in a chloride-rich environment.

AB  - Cerium-based conversion coatings have emerged as promising green alternatives to the harmful chromium-based ones, but the mechanism of corrosive protection still remains a subject of academic and industrial research. This study focuses at small scale phenomena of corrosion inhibition imparted by ceria (CeO2) to AA7075. Ceria nanoparticles were deposited from diluted and concentrated CeO2 sols by immersion. A multi-Analytical approach, combining Atomic Force microscopy (AFM), Scanning Kelvin Probe Force Microscopy, Glow Discharge Optical Emission Spectroscopy, open circuit potential and electrochemical impedance spectroscopy was employed. Deposition of ceria films led to deactivation of cathodic sites, i.e. decreased Volta potential difference, resulting in increased corrosion inhibition. In situ AFM real-Time monitoring revealed that during exposure to NaCl electrolyte, the changes in size of deposited ceria aggregates occurred: nanoparticles disintegrated/desorbed and re-deposited at the coating surface. The process was found to be dynamic in nature. Small particles size and inherent reactivity are believed to accelerate this phenomenon. Due to the greater CeO2 reservoir, this phenomenon was more pronounced with a thicker film, imparting longer term protection.

The formal decision of hosting the 71st ISE Annual Meeting was made by ISE Executive Committee in 2015, upon our proposal in 2013. The main theme of the meeting was "Electrochemistry towards Excellence" and it was planned to be held from Monday 31 August to Friday 4 September 2020. The Sava Centar was chosen as the Venue point, 22 different symposia have been proposed and defined within the meeting, covering quite a broad number of topics, 6 plenary lecturers accepted our invitations, 2 tutorials and one workshop were determined. An opening ceremony comprising the choir and folk dances was agreed on, more than 10 excursions planned, banquet dinner as well. Due to the Covid-19 pandemic and global circumstances in 2020 the 71st ISE Annual Meeting took place as a virtual one, called “Belgrade Online”, being the first ever ISE online meeting.

AB  - In this work an attempt was made to produce epoxy coating doped with ceria (CeO2) and/or zirconia (ZrO2) nanoparticles, in single step electrophoretric deposition process. Deposition was carried out on AA6060 cataforetically from epoxy resin suspension containing synthesized stable aqueous colloidal dispersions (sols) of CeO2 and ZrO2. The influence of ceria and zirconia nanoparticles on the physicochemical characteristics of epoxy coatings was evaluated by energy dispersive X-ray fluorescence spectroscopy, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy, Fourier-transform infrared spectroscopy, thermogravimetric analysis and adhesion measurements, while their corrosion stability during immersion in 0.5 M NaCl solution was monitored by electrochemical impedance spectroscopy. All ceria and/or zirconia containing coatings showed better corrosion stability and adhesion than pure epoxy coating, while between doped epoxy coatings one with CeO2/ZrO2 exhhibited the greatest values of charge-transfer resistance due to synergetic effect of both types of added nanoparticles.

AB  - Well adhered, homogenous coatings were obtained from deep eutectic solvents (DES) based on choline chloride and urea, at current densities up to 20 mA cm-2. The coatings' morphology was analyzed by atomic force microscopy, determining the agglomerates size and distribution. The corrosion stability of these deposits was analyzed in 3 wt. % NaCl solution by electrochemical impedance spectroscopy and polarization measurements, and compared with coatings deposited from a conventional water-based electrolyte. The influence of deposition current density and surface morphology, as well as of DES type, on the corrosion resistance was analyzed. It was shown that electrodeposition from DES enables incorporation of greater Mn amounts, that induced a pseudo-passivation effect, which, in turn, resulted in superior corrosion resistance.

AB  - Electrochemical impedance characteristics of bare Al and Al with CeO2 coating prepared sol-gel procedure from the ceria sol are investigated. The corrosion behavior is monitored during the exposure to 3 wt. % NaCl aqueous solution. Experimental data are fitted to various equivalent electrical circuits with special attention to inductive features. Equivalent electrical circuits involving inductivity represent impedance response equally well as the ones without inductivity, although the parameter values gained from the former correspond better to the proposed model of physicochemical changes during corrosion of investigated samples.

AB  - In this study, corrosion protection efficiency of undoped epoxy and epoxy coating doped with cerium on aluminum alloy AA6060 is evaluated over prolonged exposure to 3wt% NaCl solution by electrochemical impedance spectroscopy (EIS). Different amounts of Ce(NO3)(3) are added into the epoxy suspension used for the cataphoretic deposition. Suspension stability is characterized by zeta potential and particle size values. Water content and thermal stability of the coatings were determined by thermogravimetric analysis. Insufficient corrosion stability, very close to that of undoped epoxy, is revealed for the coating with 1mM Ce. Higher cerium doping contributes to a significant increase in corrosion stability (2-3 orders of magnitude greater charge-transfer resistance). Epoxy coating doped with 5mM Ce displays a pronounced self-healing ability and the best corrosion protection and adhesion, owing to evenly distributed cerium precipitates on the aluminum surface. In the case of 10mM Ce-doped coating, the formation of Ce clusters and higher porosity causes a certain lowering of the protective ability. EIS measurements on epoxy coating with artificial defect confirm these findings.

AB  - Ceria coating is formed on Al from the ceria sol prepared exclusively by forced hydrolysis of Ce(NO3)(4), in order to test their ability to protect Al from corrosion. The characterization of sol-gel-processed ceria coating and coating/Al assembly brings new issues on Al corrosion and protection caused by unique properties of the sol-gel coating. The corrosion behaviour of bare Al and Al/CeO2 is investigated by the electrochemical impedance spectroscopy (EIS) during the exposure to NaCl aqueous solution. The morphology and composition of the samples are examined by scanning electron microscopy and energy dispersive spectroscopy. EIS data showed greater corrosion resistance of CeO2-coated aluminium in comparison to bare Al at long exposure times. CeO2 coating does not hinder completely the corrosion processes on Al. The Al beneath CeO2 coating is subjected to intrinsic formation of a uniform protective coating/Al interphase, cross-linked by AlO(OH) fibre-like structures. They appear created by corrosive medium from the coating reversely gelled by NaCl solution. As the fibre network is created during exposure, Al becomes better protected than by spontaneous formation of porous passive layer of Al(OH)(3) on bare aluminium. Sol-gel ceria coatings thus improve corrosion resistance of aluminium during prolonged exposure to corrosive medium.

The composites with different contents of SiC micro-particles were synthesized via compo casting. Microstructural studies by means of optical microscopy (OM) and scanning electron microscopy (SEM) showed that corrosion occurred in the composite matrices, preferentially in regions of the η phase, rich in zinc. The corrosion processes did not affect the silicon carbide particles incorporated in the matrix alloy. According to the results of electrochemical polarization measurements, an increase in the content of SiC particles in the composite matrice has led to the lower corrosion resistance in the composites.

AB  - Ce-based conversion coatings (CeCCs) are a promising alternative to toxic chromate coatings on the metal substrates. In this work the CeCCs were electrodeposited on aluminium alloy AA6060 from aqueous solution of Ce(NO3)(3) at different potentials (-0.95 V, -1.2 V and -1.4V). Effect of deposition potential and post-treatment in the phosphate solution on morphology and protective properties of CeCCs with top cataphoretic epoxy coating was studied. To assess the differences between the protective systems, originating from the different CeCCs pre-treatments, electrochemical impedance spectroscopy (EIS), polarization measurements, AFM and SEM/EDS analysis were used. The EIS study was undertaken to follow the evolution of corrosion behaviour of epoxy coating/CeCCs protective systems over prolonged time of exposure to the chloride environment (3 wt.% NaCl). Results suggest significantly improved corrosion stability of epoxy coating on AA6060 with as-deposited CeCCs sub-layers with respect to the same epoxy coatings with phosphate post-treated CeCCs. The far best protective properties, i.e., the greatest value of pore resistance and the lowest value of corrosion current density were provided by the epoxy coating/CeCC protective system with CeCC deposited at -1.2V and without post-treatment.

AB  - Electrochemically deposited Zn-Ni-Co alloys under various deposition conditions were investigated using atomic absorption spectroscopy for the determination of the chemical composition, atomic force microscopy for surface morphology analysis, and electrochemical impedance spectroscopy for determination of corrosion properties. The influence of the ratio of the alloying elements, [Co2+]/[Ni2+], in a chloride deposition solution, as well as the deposition current density, on the chemical content, morphology and corrosion properties of the ternary alloys was studied. The plating solutions used were with the same overall metal concentration, free of additives and the deposition was realized at room temperature. It was shown that the deposition of the ternary alloy coatings was of anomalous type and that the ratio of nickel to cobalt ions in the plating solution, as well as the deposition current density, had a significant influence on the chemical composition and corrosion stability of these coatings. The presence of both Ni and Co was beneficial for their corrosion stability. It was shown that morphology and porosity were important factors in the corrosion stability of these coatings. The coating deposited from the solution with higher [Co2+]/[Ni2+] ratio at 8 A dm(-2) was made up of the smallest crystalline aggregates, had a small surface roughness and porosity, and was with quite uniform distribution of agglomerates and it exhibited the best corrosion stability.

AB  - Protective coatings should provide good barrier to ingress of corrosive species, sufficient adhesion to the substrate as well as good compatibility with additional top coats. The presence of pigments and/or functional agents in the coating composition could be beneficial in the corrosion protection. The doping with rare earth elements, like cerium, has shown to enhance the corrosion stability of organic coatings due to their self-healing properties. In this work cerium doped nanometric epoxy primers were deposited cataphoretically with different amounts of cerium nitrate (1, 5 and 10 mM) with the aim of optimizing the cerium content in the epoxy emulsion with respect to adhesion and corrosion stability of deposited primer coating. Cerium-free epoxy coating was also analyzed as a reference. The long term protection was evaluated in the chloride environment (3 wt.%NaCl) using electrochemical impedance spectroscopy (EIS) and polarization measurements. Coatings were also analyzed by scanning electron microscopy (SEM) coupled with EDX, Fourier transform infrared spectroscopy and thermogravimetric measurements. Size and zeta potential of epoxy emulsion were measured by dynamic light scattering and Laser Doppler velocimetry. Adhesion was determined both by a standardized pull-off method and by swelling in N-methyl pyrrolidone. The ceria content, as well as its distribution in the epoxy coating, was determined by SEM cross-sectional analysis. The homogeneity of epoxy coatings was evaluated and related to corrosion stability. The results showed that cerium-doping can promote the formation of compact epoxy coatings with enhanced protectiveness in the early stage of immersion in the corrosive media. Increased barrier properties of epoxy primers suggest good compatibility of ceria particles with polymeric epoxy layer. However, zeta potential measurements indicated that higher amounts than 10 mM Ce(NO3)3 added into the epoxy emulsion resulted in unstable emulsion. The water content in the epoxy coatings and their thermal stability were also determined. In addition, a detailed EIS study was undertaken to follow the evolution of corrosion stability of all samples with time of exposure to corrosive media. It was shown that all examined ceria containing epoxy emulsions resulted with the enhanced adhesion and corrosion stability of epoxy primers. However, the smallest loading of 1 mM showed only improvement during the initial exposure to NaCl solution. EIS and polarization measurements confirmed that higher ceria loadings also provide long term protection in chloride solution.The optimal ceria content in the epoxy emulsion, with respect to adhesion strength, thermal stability and long-term corrosion stability of protective systems was 10 mM.

AB  - Among potential replacements for chromates, cerium-based conversion coatings (CeCCs) have been identified as leading candidates, showing a good promise as environmentally compliant corrosion inhibitors on Al alloys. In this work, CeCCs were synthesized on M6060 by electrolytic deposition (ELD), a well-suited method for the fabrication of films with controllable properties, at low processing temperature and cost. The CeCCs were deposited at room temperature from Ce(NO3)(3) solution, applying different cathodic potentials (-1.1, -1.4 and -1.6 V vs. SCE) for different deposition times between 5 and 20 min. Structural, morphological and compositional properties of the films were characterized by X-ray diffraction, Raman spectroscopy and scanning electron microscopy coupled with energy dispersive spectroscopy. Ceria films were nanostructured, exhibiting a cubic fluorite structure. From corrosion perspective, the quality of CeCCs was evaluated in 0.5 M NaCI solution via electrochemical impedance spectroscopy and linear sweep voltammetry. As shown, the coating corrosion quality is the interplay between deposition potential and deposition time. The highest potential led to highly cracked films of poor adherence, even at the shortest deposition time, which disqualified them from any corrosion protection application. The lowest potential (-1.1 V) produced crack-free coatings, but longer times (>= 10 min) were needed to provide the protective layer formation. The best corrosion protection offered CeCCs prepared at -1.4 V. The highest R-p (582 k Omega cm(2)) and the smallest CPE (12.6 . 10(-6) s(n) Omega(-1) cm) were obtained at 20 min deposition time. However, from economical point of view, 10 min deposition is a promising choice. These CeCCs also improved pitting corrosion resistance owing to homogeneous microstructure and sufficient thickness.

AB  - Zn - Mn alloy electrodeposition on steel electrode, in electrolytes containing chloride or sulfate anions, was investigated by chronopotentiometry. Galvanostatically obtained electrodeposits were characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), and atomic absorption spectrophotometry (AAS). It was found that Zn2+ and Mn2+ ion reduction occurred at higher overpotentials in sulfate bath, leading to a higher Mn content in the deposit and smaller crystallites as compared to the chloride electrolyte. AFM images of deposits revealed that with the increase in deposition current density, bigger agglomerates formed in both electrolytes, leading to higher roughness and heterogeneity of the samples. In relation to this observation, the Zn - Mn coatings were deposited at current densities of up to 80 mA cm(-2) because at higher current densities the samples from sulfate electrolyte were non adherent and dendritic. Depending on the deposition current density, the XRD patterns of the Zn - Mn deposits produced from chloride electrolyte indicated that the coatings were formed of either eta- or epsilon-Zn-Mn phase, while the coatings obtained from sulfate bath consisted of epsilon-Zn - Mn phase. The linear polarization method showed that Zn - Mn alloys deposited from sulfate electrolyte exhibited higher corrosion resistance in NaCl corrosive media.

AB  - Dip-immersion is a simple and cost-effective method for the preparation of Ce-based conversion coatings (CeCCs), a promising alternative to toxic chromate coatings, on metal substrates. In this work, CeCCs were prepared on Al-alloy AA6060 from an aqueous solution of cerium chloride at room temperature. The effect of immersion time and post-treatment in phosphate solution on the microstructure and corrosion properties of the coatings was studied. The longer the immersion time was, the thicker but more nonhomogeneous and cracked were the CeCCs. The post-treatment contributed to a sealing of the cracks, as proven by an increase in the corrosion resistance compared with the as-deposited coatings. The CeCCs prepared at longer deposition times and post-treated showed much better corrosion protection than those prepared at shorter deposition times. A detailed electrochemical impedance spectroscopy (EIS) study was undertaken to follow the evolution of the corrosion behaviour of the CeCCs with time of exposure to an aggressive chloride environment (3.5 % NaCl). For the sake of comparison, the EIS properties of bare AA6060 were also investigated. Linear voltammetry was performed to complete the study. The results confirmed the formation of protective CeCCs on the surface of AA6060. However, even CeCCs prepared at longer deposition times and post-treated provided short term protection in the aggressive environment, due to the small thickness of the coating.

AB  - Cerium-based conversion coatings (CeCCs) are one of the most prospective alternatives to the widely used chromate conversion coatings (CCCs) due to their anticorrosion efficiency, environmentally friendly nature and low cost. In this work, the CeCCs on AA6060 were prepared by immersion into aqueous cerium salt solutions at room temperature, and subsequently post-treated in heated phosphate solution. The effect of counter ion (nitrate and chloride) on the coating properties was studied testing CeCCs as sole or conversion layers for the top polyester coating. Since the 60 mu m thick polyester coating was applied, an artificial defect of 0.8 mm hole was introduced to faster assess the differences between pretreatments. The system with CCC pretreatment was used as reference. Corrosion properties were investigated in 0.5 M NaCl solution by electrochemical impedance spectroscopy while the adhesion strength was measured by NMPR (N-methyl-2-pyrrolidone) and pull-off tests. As shown, the post-treated chloride-based CeCC offered better protection than crack-free thin nitrate-based CeCC, when used as sole coatings. On the other hand, it was brought to evidence that in combination with top powder polyester coating, the CeCC deposited from nitrate solution exhibited better protection compared to protective system pretreated with chloride-based one. Excellent polyester coating adhesion was found independently on aluminium surface pretreatment.
