Anti-Wear Property of Self-Repairing Mineral Particles as Grease Lubricant Additives on the Metal Friction Pairs

Wen Gang Chen, Yu Gao, Hui Chen Zhang, Ze Fei Tan

Abstract

The characteristics of the 1045 steel pairs using serpentine particles as grease lubricant additive were investigated by an AMSLER friction and wear tester. The surface topographies and composition of the worn surface of 1045 steel rings were identified by SEM and XPS. The results show that the additives can form a self-repairing film on the worn metal surface. It can reduce the abrasion of the friction pairs significantly. The main elemental compositions of the film are Fe, O, Si, C and Mg, which indicates that the additives directly take part in the formation of the self-repairing film.
