摘　　要：介绍了ZECCOAT无铬钝化工艺。该工艺采用了高科技纳米技术,钝化液无毒,钝化膜薄且具有自修复性,钝化产品的耐蚀性高。生产实践表明:ZECCOAT无铬钝化的成本与传统三价铬钝化加封闭工艺的大体相同。中性盐雾试验结果表明:采用三价铬钝化+ZECCOAT无铬钝化与直接采用ZECCOAT无铬钝化相比较,产品的耐蚀性得到了明显的提高。The ZECCOAT chromium-free passivation process is presented. The process features high-tech nanotechnology, non-toxic passivation solution, thin and self-reparative passivation film as well as high corrosion resistance of passivated products. The production practice shows that ZECCOAT chromium-free passivation process is about the same with traditional trivalent chromium passivation ＋ sealing process in cost. Neutral salt spray test results show that compared with directly using ZECCOAT chromium passivation, the use of trivalent chromium passivation -- ZECCOAT chromium passivation can significantly improve the corrosion resistance of products.
