摘要： 以菜子油为基础油,在四球摩擦磨损实验机上分别考察了硫系添加剂T321与T307以及磷系添加剂P120对菜子油的耐磨性和极压性能的影响·结果表明,在菜子油中分别加入T321、P120和T307能够降低磨损、提高润滑油膜的承载能力和极压载荷·对钢球表面的能谱分析结果表明,在摩擦磨损过程中,含上述添加剂的菜子油在摩擦过程中发生了摩擦化学变化,生成了由菜子油三甘油酯和添加剂化学产物组成的边界润滑膜,从而改善抗磨性能并提高承载能力·

Abstract: Taking rapeseed oil as base constituent, the three lubricant additives, ie. sulfur-system T321 and T307 and phosphorus-system P120, were investigated separately on a 4-ball friction-wear tester with the intention of how they improve the wearability and extreme pressure characteristics of rapeseed oil. The results showed that they all are beneficial to reduce wear-out and improve the load capacity and resistance to extreme pressure of lubrication film. The SEDX (Spectral Energy Distribution X-ray) analysis of steel ball surfaces revealed that there are tribochemical reactions of the rapeseed oil containing any of the three additives during friction/wear process, thus forming a boundary lubrication film composed of triglyceride and others produced from the reacted additive to improve the wearability and load capacity.
