用粉末冶金法制备了Ｎｉ－Ｃｒ－Ｍｏ－Ａｌ－Ｔｉ－Ｂ－ＭｏＳ２系宽温度范围自润滑合金材料，测试了合金机械性能及其在室温至６００ ℃范围内的摩擦磨损性能，同时还探讨了其耐磨机理．研究结果表明，ＭｏＳ２ 质量分数为１０％ 的合金具有较好的机械和摩擦磨损综合性能．该合金主要由Ｎｉ基固溶体、Ｎｉ３Ａｌ、Ｎｉ３（Ａｌ，Ｔｉ）、不定比化合物ＣｒｘＳｙ、ＭｏＳ２ 和Ｍｏ２Ｓ３ 等相组成，在室温至３００ ℃范围内摩擦表面形成含硫化合物复合膜而起润滑作用，高温摩擦时承载表面形成釉质层，次表层形成氧化层，其硬度比合金基体高，这是合金具有良好高温耐磨性的基础．高温下摩擦表面及磨屑中的氧化物及残余硫化物的协同作用使摩擦系数进一步降低．
The Ni-Cr-Mo-Al-Ti-B-MoS2 wide temperature range self-lubricating alloy was prepared by powder metallurgy. The mechanical properties of the alloy and its friction and wear properties at room temperature to 600 ℃ were tested. The wear mechanism. The results show that, MoS2 mass fraction of 10% of the alloy has good mechanical and tribological properties. The alloy is mainly composed of a Ni-based solid solution, Ni3Al, Ni3 (Al, Ti), an indefinite compound CrxSy, MoS2 and Mo2S3 and the like, and forms a sulfur compound compound film on a friction surface at a temperature ranging from room temperature to 300 DEG C to lubricate, Friction bearing surface formation of enamel layer, subsurface oxide layer, the hardness higher than the alloy matrix, which is the alloy with good high temperature wear resistance of the foundation. The friction coefficient is further reduced by the synergistic effect of oxides and residual sulfides in the friction surfaces and wear debris at high temperatures.
