摘　　要：本文介绍了超音速电弧喷涂技术制备锌铝合金涂层的过程和工艺,对涂层进行了电化学测试。结果表明合金涂层可以起到牺牲阳极的作用,同时浸泡一段时间之后合金涂层表面可以生成钝化膜。锌铝涂层可以保护钢铁基体不被腐蚀。This paper introduces the process and technology of preparing Zn-Al alloy coating by supersonic velocity arc spraying. The coating was tested by electrochemical methods. The results show Zn-Al coating play a sacrificial anode role in corrosion process, and there is passive film in the surface of Zn-Al coating after immersing. So the base alloys are effectively protected.
