Abstract

Abstract

The chemical stability of Zn-Ni alloy coating containing 12%~13% Ni is further improved in this paper by means of a new chromation process and its corrosion resistance is five times higher than unchromation one.The effects of the composition of chromate solution and operation conditions on formed mechanism of conversion coating were investigated,and the protective mechanism of the coating was also discussed.
