摘　　要：烧结式锌铝涂层具有较好的抗腐蚀性,无氢脆,耐高热,整个涂覆过程采用闭路循环涂覆方式,具有全过程无污染、无排放特点,可代替电镀锌工艺。紧卷着的弹簧经涂覆处理后,在拉伸的状态下进行盐雾试验,仍能显示出良好的防锈能力,因此烧结式锌铝涂层适合于高强度弹簧防腐蚀保护。Sintered zinc-aluminium coating has better anticorrosion performance,no hydrogen brittleness and has hot resistance performance.A closed-loop recirculating coating mode is used in paint process,and there is no pollution and emission in whole production process.Sintered zinc-aluminium can be used to replace galvanizing process.From the erode tests in salt-fog,it is shown that the zinc-aluminium coating presents more excellent anticorrosion property than the conventional electroplating zinc coating,even if the springs were outspread after coating.Sintered zinc -aluminium coating is suitable for corrosion protection of high strength spring.
