Anti-friction material based on ultrahigh molecular weight polyethylene, filled with solid lubricating fillers
For comparative evaluation of effectiveness of the solid lubricating fillers for composites based on ultrahigh molecular weight polyethylene investigated tribological characteristics of UHMWPE compositions with graphite and molybdenum disulfide in the dry friction condition. It is shown that the wear rate of UHMWPE-graphite and UHMWPE-MoS <sub>2 </sub>polymeric compositions under dry sliding friction is reduced by half compared to pure UHMWPE. Thus mechanical properties vary slightly. The optimum content of fillers in terms of wear resistance improving was determined. Investigated supermolecular structure and topography of wear surface of UHMWPE compositions with different content of fillers.
