摘要
机械镀Zn-25%Sn合金镀层因其良好的耐盐水和含盐蒸气腐蚀性能,适宜在海洋性腐蚀环境中服役,已被澳大利亚等临海国家广泛应用并列入其工业标准。本试验分别采用还原沉积和携带沉积两种方法在钢铁制品表面上获得了平均锡含量达25%以上的机械镀Zn-Sn合金镀层。针对样品的镀层结构和形层规律进行的分析比较结果表明:在不同的沉积条件下,还原沉积Zn-25%Sn镀层的形成以还原沉积和机械碰撞镶嵌形层为主,吸附沉积为辅;携带沉积Zn-25%Sn镀层的形成以吸附沉积和机械碰撞镶嵌形层为主,还原沉积为辅。
Mechanically deposited zinc-tin(25%) alloy coating,due to its excellent performance in brine,vapor,and marine exposure environment,had been widely used and listed in industrial standard of costal country like Australia.In our experiment,mechanically deposited zinc-tin(25%) alloy coating was prepared using tin reduction deposit and zinc-tin adventitious deposit method respectively.Results of structure and forming process analysis for the above mentioned coating samples show that under different deposit circumstances,zinc-tin reduction deposition and particle collision and inlay are predominant in the forming process of zinc-tin(25%) alloy coating using tin reduction deposit method,accompanied with zinc and tin powder adsorption deposition;by contrast,zinc and tin powder adsorption deposition and particle collision and inlay,which are accompanied by tin reduction deposition,are in leading position in the forming process of zinc-tin(25%) alloy coating using zinc-tin adventitious deposit method.
