Abstract
The results of immersion tests in fuel ethanol performed using several types of metallic and inorganic coatings are presented. The following coatings applied on carbon steel were tested: aluminum; chromatized cadmium; lead; hard chromium; Dacromet® (a special zinc coating); phosphate coating, nickel; zinc; chromatized zinc. Anodized aluminum was also studied. Among the tested coatings, the hard chromium and the nickel coatings presented the best performance. The Dacromet® coating and the anodized aluminum also presented satisfactory performance. The zinc, lead and the phosphate coatings did not present a good performance.
