Improvement of wear resistance of UHMWPE by adding solid lubricating fillers

Abstract

For estimating effectiveness of adding solid fillers for composites with ultra-high molecular weight polyethylene matrix tribotechnical characteristics of UHMWPE mixture with graphite, molybdenum disulfide and polytetrafluoroethylene were investigated under dry friction, boundary lubrication and abrasion. The optimum filler weight fraction was determined in terms of increasing wear resistance. Permolecular structure and surface topography of wear tracks for UHMWPE composites with different weight fraction of the fillers was studied. The mechanisms of wear of polymeric composites "UHMWPE-graphite", "UHMWPE-PTFE" and "UHMWPE-MoS₂" under dry sliding friction and abrasive wear are discussed.
