镀锌钢板表面新型环保钝化膜的抗腐蚀性能研究
|
摘要
对采用不同表面处理的镀锌钢板进行微观组织、化学成分、电化学性能和腐蚀性能测试,分析了不同钢板的耐腐蚀机理。结果表明,镀锌钢板表面新型环保钝化膜表现出优异的耐腐蚀性能,其中所加入的封孔剂弥补了三价铬钝化不足的缺陷,提高了其耐腐蚀性能。
The microstructure,chemical composition,electrochemical property and corrosion property of the galvanized steel with different surface treatments were studied,and the corrosion mechanism was analyzed. The results show that the galvanized steel with novel environmentally film shows excellent corrosion property. The corrosion resistance is improved by the sealer in the passivation film which make up the lack of trivalent chromium.
