Tribological Studies of Epoxy Composites With UHMWPE and MoS2 Fillers Coated on Bearing Steel: Dry Interface and Grease Lubrication

Abstract: Epoxy with ultra-high molecular weight polyethylene (UHMWPE) and MoS2 fillers was coated on a bearing steel (SAE 52100). Frictional and wear properties of the coated samples in sliding contact were investigated on a pin-on-disc tribometer under a normal load of 10 N and a linear sliding speed of 1 m/s against a bearing steel ball. The optimized coating composition (72 wt% Epoxy + 7 wt% hardener + 18 wt% UHMWPE + 3 wt% MoS2) showed highly improved tribological properties compared to pure epoxy and other epoxy-b… Show more

“…Many organic polymers such as ultra-high molecular weight polyethylene (UHMWPE), PTFE, and polyethylene wax (PEW) have excellent self-lubrication such as high wear resistance and low friction. [75][76][77][78][79] By adding polymer powders to the PU matrix, the tribology properties and aging resistance can be enhanced for extending the service life of materials effectively.…”
