摘要
采用中性盐雾腐蚀试验，对乙醇—苯骈三氮唑钝化工艺进行了改进，研制出ＷＰ─１型镀铜焊丝钝化剂。电镀和化学镀铜焊丝经钝化后抗蚀性能均有明显提高。
Through corrosion experiment of neutral salt spray(NSS),the new technology of adding a kind of passive accelerator to the passive system of ethyl alcohol-benzotrial-chloride-zole has been studied.A new WP-1 type passivation-promotor was selected.After passive treatment,the rustproof ability of kinds of coppered welding wires has been improved obviously.
