Film Formation Property of Mineral Particles as Grease Lubricant Additives at Different Friction States

The characteristics of the 1045 steel pairs using superfine mineral powder as grease lubricant additive were investigated by an AMSLER friction and wear tester at different wear states. The surface topographies and composition of the worn surface of 1045 steel rings were identified by SEM and EDAX. The surface roughness of the samples was investigated by a profilometer. The results show that the additives can form a self-repairing film on the worn metal surface at Sliding state and there no film formed on the worn metal surface at Rolling-Sliding state. The reason is that the friction heat and friction energy produced by Sliding friction higher than the friction heat and friction energy produced by Rolling-Sliding friction.

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

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.
