摘　　要：综述了国内外替代镀锌 (合金 )钢板铬酸盐钝化工艺的多种无 /低铬钝化技术及当前研究状况 .Chromate conversion coatings produce a good corrosion resistance on zinc.However,because of the toxicity of chromate,the pressure to move away from passivation processes based on chromate is becoming ever more intense.Selection of alternatives to hexavalent chromium is of prime importance.The chromate-free passivation technique and its development on zinc or zinc alloy galvanized-steel is reviewed.
