摘　　要：为了寻求一种良好的真空轴承润滑方式,将六方氮化硼(h-BN)纳米颗粒作为全氟聚醚(PFPE)基润滑脂添加剂,制备PFPE/h-BN纳米颗粒复合润滑脂,对比测试国内外三种真空润滑脂的滴点、腐蚀和蒸发量等性能参数,通过表面织构技术对轴承材料表面进行处理,并利用摩擦磨损实验,综合考察了PFPE/h-BN纳米颗粒复合润滑脂在不同织构表面的润滑性能。结果表明,PFPE/h-BN纳米颗粒复合润滑脂有利于提高真空轴承的润滑性能,轴承材料表面织构处理后,提高了复合润滑脂摩擦磨损实验的稳定性,且降低了摩擦系数。In order to find a good way to improve the lubrication performance of vacuum bearing,hexagonal boron nitride(h-BN) nanoparticles were used as perfluorinated polyether(PFPE)-based grease additives to prepare composite greases,and tested and compared the drop point,corrosivity and evaporation capacity of the grease.The bearing material was processed by the surface texture technology,and the lubricating performance of the composite grease on different textured surfaces was comprehensively investigated through the friction and wear test.The results shown that PFPE/h-BN nanoparticles composite grease shown good lubrication performance.After the surface texture treatment,the stability of the composite grease friction and wear test was improved,and the friction coefficient was lower than that without any treatment.
