Evaluation of corrosion resistance of metallic coatings in hydrated ethanol fuel (EAHC). Part I – laboratory testing

Abstract:

The results of immersion corrosion tests with different metallic coatings in ethanol fuel are presented. The following coatings on steel were tested:aluminium, cadmium, chromate finished cadmium, lead, hard chromium, Dacromet (a type of zinc coating), phosphate, nickel, zinc, chromate finished zinc and zinc/aluminium. Anodized aluminium was also tested. The corrosion resistance of cadmium, hard chromium, nickel, Dacromet and anodized aluminium was adequate, while that of zinc, lead and phosphate was not. The influence of Cl- and SO4- – ions on corrosion resistance of more resistant coatings was also investigated.
