摘要
综述了锌及锌合金镀层无铬钝化的研究进展情况;介绍了几种无机、有机钝化工艺。展望了无铬钝化技术的发展趋势,同时指出:硅酸盐钝化膜是无毒、环保型保护膜,耐蚀性较高,钝化成本较低;因此,硅酸盐钝化将成为替代铬酸盐钝化工艺的主要研究方向之一。
Progress of chromate-free passivation of zinc or zinc alloy galvanized steel is summarized, focusing on several chromate-free passivation processes of zinc plated steel by inorganic and organic agents, The developing tendency of chromate-free passivation techniques is overcasted. It is also pointed that silicate passivation film will be one of the main researching objects, which will replace current traditional chromate passivation because it is non-toxic and environment-friendly, highly corrosion resistant and lower in cost.
