摘要:
采用纳米电刷镀技术在淬火后45钢表面制备Zn涂层，对其进行低温离子渗硫处理得到复合Zn/ZnS层。考察了该复合涂层在大气和真空环境下的减摩润滑性能。结果表明，高真空环境下，刷镀层孔隙有增多、变大现象。大气环境的摩擦试验过程中，暴露的新鲜涂层与大气中的氧作用形成氧化膜，导致磨损严重，润滑性能降低，摩擦因数在0.23左右。真空中的减磨润滑效果较好，摩擦因数相对较低，在0.18左右。

Abstract:
Nano electro–brush plating was used to prepare Zn coating on the surface of quenched 1045 steel, and then the Zn coating was sulfurized to obtain Zn/ZnS composite layer. The tribological properties of the compound Zn/ZnS layer were investigated in air and vacuum atmosphere respectively. The results show that the pores of electro-brush plating layer became more and larger in high vacuum atmosphere. During the wear process in air, the exposed fresh coating acted with the oxygen in the atmosphere to generate an oxide film, resulting in the decline of lubricating property in the atmosphere. The friction coefficient in air was 0.23. In contrast, the lubricating effect in vacuum was superior, and the friction coefficient in vacuum was 0.18.
Key words:  nano-electro-brush plating  low temperature ion sulfurizing  vacuum  tribological properties
