EFFECTS OF HEATING CHROMATE CONVERSION COATINGS

reportActive / Technical Report | Accession Number: AD0685089 | Open PDF

Abstract:

Chemical chromate conversion coated zinc, cadmium, aluminum and magnesium were oven heated at temperatures from 50 to 200C and subsequently tested for salt spray corrosion resistance. Chromated zinc and aluminum were adversely affected in corrosion resistance after exposure to air temperatures above 100C. Exposure to elevated temperatures resulted in insolubilization of hexavalent chromium and cracking of the chromate coating.
