摘要:: 针对被广泛应用于制造仪器仪表、轴承套圈、柱塞的GCr15钢材料，目前存在宽载荷范围下易摩擦磨损问题。本文创新性的制备了一种新型富含固体润滑剂MoS2的GCr15球形粉末，再通过放电等离子烧结技术将球形粉末烧制成GCr15基自润滑复合材料，对其摩擦学特性进行研究。研究结果表明：MoS2稳定存在于GCr15粉末中，且与GCr15基体结合状态良好；MoS2的添加对降低GCr15钢的摩擦系数及磨损率具有显著效果(降低30%以上)，这主要归功于在摩擦过程中固体润滑剂MoS2富集于摩擦表面形成的减摩耐磨层。研究结果可为新型复合润滑剂设计及金属基滑动部件摩擦性能提升研究提供指导。

Abstract:: GCr15 steel material, which is widely used in the manufacturing of instruments, bearing rings, and plungers, currently has the problem of easy friction and wear under a wide load range. This article innovatively prepares a new type of GCr15 spherical powder rich in solid lubricant MoS2, and then uses discharge plasma sintering technology to sinter the spherical powder into GCr15 based self-lubricating composite material, and studies its frictional properties. The research results indicate that MoS2 is stably present in GCr15 powder and has a good bonding state with the GCr15 matrix; The addition of MoS 2 has a significant effect on reducing the friction coefficient and wear rate of GCr15 steel (by more than 30%), mainly due to the accumulation of solid lubricant MoS 2 on the friction surface during the friction process, forming a friction reducing and wear-resistant layer. The research results can provide guidance for the design of new composite lubricants and the study of improving the friction performance of metal based sliding components
