摘    要:湿热大气环境对MoS2润滑薄膜的摩擦学性能有严重的劣化作用。采用非平衡磁控溅射技术成功制备了WS2掺杂MoS2复合薄膜,研究发现,MoS2基体中掺入少量WS2可以诱导MoS2沿(002)晶面择优生长,薄膜结构变得更加致密,显著抑制腐蚀介质的渗透和扩散,使MoS2/WS2复合薄膜展现出高盐雾耐蚀性、小摩擦因数和低磨损率。成分优化的MoS2-1.6%WS2(原子分数)复合薄膜在经历4天的盐雾试验后仅表层被氧化,仍能保持0.16的小摩擦因数和3.80 × 10-6 mm3/(N·m)的低磨损率。

关 键 词:MoS2/WS2复合薄膜  盐雾环境  耐腐蚀性  摩擦学性能

Abstract:The hot and humid atmosphere had a serious deteriorating effect on the tribological properties of the MoS2 lubricating films. Unbalanced magnetron sputtering technology was successfully used to prepare WS2 doped MoS2 composite films, and the addition of a small amount of WS2 in the MoS2 matrix might induce the preferential growth of MoS2 along the(002) crystal planes, the film structure became denser, the penetration and diffusion of corrosive media were significantly inhibited, and the MoS2/WS2 composite film exhibited high salt spray corrosion resistance, low friction coefficient and wear rate. The composition-optimized MoS2-1.6at.%WS2 composite film was only oxidized on the surface layers after 4 days of salt spray, and still maintained a low friction coefficient of 0.16 and a low wear rate of 3.80×10-6 mm3/(N·m). 
Keywords:   MoS2/WS2 composite film  salt spray environment  corrosion resistance  tribological property
