CORROSION BEHAVIOUR OF A 2219 ALUMINIUM ALLOY TREATED WITH A CHROMATE CONVERSION COATING EXPOSED TO A 3.5 % NaCl SOLUTION
This study investigates the formation of a chromate conversion coating at Al-Cu-Fe-Mn intermetallic sites of an Al2219 alloy and the corrosion initiation at these sites in a 3.5 % NaCl solution, using SEM, AES and EDX. Changes in the surface chemistry were monitored after progressive exposures to the solution up to 42 hours. The coating was found to be thinner and more defective on the intermet...
متن کاملA New Polymeric Nanocomposite Coating for Corrosion Protection of Carbon Steel in HCl Solution
In the present work, four polymeric nanocomposite PNC coatings were prepared with different concentrations of yttrium aluminum garnet nanoparticles YAG-NPs in polyvinyl butyral PVB matrix. The corrosion protection of the PNC coatings applied on the carbon steel surface was investigated in 1.0 M HCl solution by electrochemical impedance spectroscopy EIS. The YAG-NPs were synthesized by pulse ele...
متن کاملTrivalent Chromium Conversion Coating for Corrosion Protection of Aluminum Surface
Corrosion is the degradation or deterioration of metal components due to a reaction with the environment. Chromate conversion coating is applied to passivate metallic surface to slow down (and prevent to some extent) corrosion process. Chromate conversion process uses chromium compounds including hexavalent chromium, which is toxic, carcinogenic and hazardous to human health and environment. He...
متن کاملPerformance of Tannin/Glycerol-Chromate Hybrid Conversion Coating on Aluminium
A smart hybrid conversion coating has been developed. Modifications of coating solutions with poly-hydroxyl organic materials to reduce the usual mud cracking pattern characteristics of chromate conversion coatings (CCCs) and improve its ability to release inhibitors to corroding sites have been achieved. The smart functionalised chromate conversion coating (SFCCC), developed on aluminium subst...
متن کاملEnhancement of Adhesion Properties, Corrosion Resistance and Cathodic Disbonding of Mild Steel-Epoxy Coating Systems By Vanadium Conversion Coating
In this study, vanadium conversion coating(VCC) was deposited on the surface of soft-cast steel (St-37). A thermoset coating was enforced on the VCC and blank substrates. The surface was characterized by field emission scanning electron microscope (FE-SEM), elemental mapping of energy dispersive X-ray (EDX) and atomic force microscopy (AFM). The adhesion strength...
