MoS₂-Cr₃O₄ composite films were prepared by the combination method of PVD and liquid phase synthesis. The microstructure and tribological properties of films have been investigated. The results indicate that the size of Cr₃O₄ varied from 5 nm to 500 nm and the shape of Cr₃O₄ changed from nanospheres to nanorods by adjusting concentration of CrCl₃. The MoS₂-Cr₃O₄ composite films developed excellent wear resistance and much lower friction coefficient than sputtered MoS₂ both in vacuum and 45%RH air. During friction, the Cr₃O₄@MoS₂ core-shell structure with Cr₃O₄ core of high hardness and soft MoS₂ shells were formed and played the role of nano-bearing, which reduced the friction and wear of the composite film. Besides, better oxidation resistance and tribological property of the MoS₂-Cr₃O₄ composite films in humid air were attributed to the Cr₃O₄ nanoparticles, which occupied the most of dangling bond sites.

通过PVD和液相合成相结合的方法制备了MoS ₂ -Cr ₃ O ₄复合膜。研究了薄膜的微观结构和摩擦学性能。结果表明，Cr的大小₃ ø ₄从5纳米至500纳米和Cr的形状变化₃ ö ₄通过调节的CrCl的浓度从纳米球改变为纳米棒₃。MoS ₂ -Cr ₃ O ₄复合膜在真空和45％RH的空气中比溅射的MoS ₂具有优异的耐磨性和低得多的摩擦系数。摩擦时，Cr形成了具有高硬度的Cr ₃ O ₄核和柔软的MoS ₂壳的₃ O ₄ @MoS ₂核-壳结构，并起到了纳米轴承的作用，从而降低了复合膜的摩擦磨损。此外，MoS ₂ -Cr ₃ O ₄复合膜在潮湿空气中具有更好的抗氧化性和摩擦学性能，这归因于Cr ₃ O ₄纳米颗粒占据了大多数的悬空键位。
