摘要：

Epoxy, Ultra High Molecular Weight Polyethylene (UHMWPE), Molybdenum disulphide (MoS2) composite was coated onto a bearing steel. Frictional and wear properties were investigated under a normal load of 10.5 N and sliding speed of 1m/s against a bearing steel ball. The optimized coating composition shows improved tribological properties compared to pure epoxy and other epoxy-based composites. There is 71% reduction in the coefficient of friction under dry condition (mu reduces from 0.2 to 0.05) and 80% reduction with grease. Hardness, and Young's modulus show an increment of 86%, and 43% respectively with respect to pure epoxy. The present composite will have applications as coating and bulk material in several types of bearings.
