摘要
六价铬钝化因其具有自我修复、优异的抗腐蚀性能是最常用的钝化工艺。通过对德国汉高六价铬钝化液的解析,研究了钝化液中各组分对钝化工艺的影响:耐盐雾时间72 h腐蚀率为零,96h腐蚀面积小于5%,满足工业生产的要求。
The hexavalent chromium passivation process is the most common, because of its self-healing, excellent corro-sion resistance. Based on the analysis of Henkel hexavalent chromium passivation solution, studied the influence of differ-ent components in passivation solution passivation process. The results showed that the salt spray time is 72 h, the corro- sion rate is zero, and the corrosion area of 96h is less than 5%, which meets the requirements of industrial production.
