摘要/Abstract

摘要： 研究了一种磷氮型极压抗磨剂在锂基润滑脂中的摩擦学性能，通过四球试验、SRV试验和振荡摩擦磨损试验比较了基础脂和含有添加剂润滑脂的极压抗磨减摩性能，并通过三维形貌仪进行了形貌分析，验证试验结果。结果表明：磷氮型极压抗磨剂添加质量分数为3.0%时具有突出的抗磨和减摩性能及较好的极压性能，极压减摩抗磨机理是磷氮型添加剂在摩擦副表面形成含氮富磷的边界润滑膜。

Abstract: The tribological properties of a nitrogen phosphorus type extreme pressure anti-wear agent in lithium base grease were studied. Four ball test, SRV test and oscillating friction and wear test were carried out to compare the extreme pressure anti-wear and friction reduction properties of base grease and grease containing additives under extreme pressure. The results showed that P-N extreme pressure anti-wear additive with a mass fraction of 3.0% had outstanding anti-wear and antifriction properties and better extreme pressure properties. The anti-friction and anti-wear mechanism of extreme pressure was the formation of nitrogen and phosphorus-rich boundary lubrication film on the surface of the friction pair.

Key words: extreme pressure additive, friction test, three-dimensional topography, action mechanism
