Aluminium gets attacked by different media and several surface treatments are used for effectively reducing corrosion. Of these, the versatile method is anodising the aluminium surface, the others being chromating and phosphating. However, these treatments give only short-term protection. The application of protective paint coatings over the surface gives long term corrosion protection. The bond strength of paint coatings over bare aluminium is found to be far from satisfactory and hence conversion coatings are first given over which paints are applied. This papers deals with a study of the comparative performance of coatings with different conversion coatings applied over aluminium. The performance of the coatings has been assessed by adhesion tests, salt-spray tests and electrochemical impedance tests. SEM (scanning electron microscopy) studies are also carried out to examine the surface morphology to the pretreated surfaces of aluminium
