摘　　要：提出了一种以锌钙系磷化液为主体的铅-3%锑合金电化学磷化新工艺。电化学测试结果表明:合金经过磷化后,表面形成的磷化膜能有效阻止其在3%NaCl溶液中的腐蚀,使合金的稳定性得到提高。该工艺所用试剂不含有害促进剂,磷化过程无污染,技术环保,具有工业推广价值。A kind of electrochemical phosphating method was employed to lead-3%antimony alloy in the phosphating solution of calcium-zinc series. The electrochemical tests indicated that the phosphating film could prevent the corrosion of the alloy in 3%NaCl aqueous solution, and the stability of the alloy was improved after phosphating. This phosphating process has advantages such as no harmful accelerant, free from pollution, environmental friendly and wide application value in industry expansion.
