“…shape of threads (fibers). This result agrees well with the data on tensile tests of the UHMWPE + LLDPE-b PP composite described in [4]. The friction coefficient of the composites was varied not significantly regardless the weight fraction of the polymeric filler ( It is clearly seen that microscratches on the wear track surface are formed in the pure UHMWPE specimens, that indicates microadhesion pattern of their wear (Fig.…”

“…An important technological problem for developing anti-friction composites based on UHMWPEmatrix is finding out compatible polymeric fillers (elasticizing additives) that makes possible both increasing its tribological characteristics [1][2][3] as well as improving extrudability of mixtures. In papers [4][5][6] there were examined the polymer-polymeric composites with UHMWPE matrix mixtured with polyethylene and polypropylene. The interfacial bonding between the polymeric components of the mixture was ensured through using polymeric filler like crosslinked polyethylene (PE-C), linear low density polyethylene in block with PP (PP-b-LLDPE), as well as high density polyethylene in block with EVA (HDPE-b-Ethyl-Vinyl-Acetate).…”

“…Influence of these commercially available processing additives onto technological properties (in particular, extrudability) of (nano-and micro-) composites based on UHMWPE were been studied. In particular, it was shown in [4] that high wear resistance under dry sliding friction of the composition "UHMWPE + n wt. % PP-b-LLDPE" is determined by deformation and wear processes localization in the PP-b-LLDPE particles (with diameter up to 200 µm) being additionally reinforced by small UHMWPE particles (with diameter up to 5 µm) embedded during hot compression that provided effective sliding of steel counterface over the specimen surface.…”

In order to find out optimum filler to increase manufacturability (extrudability) of composites based on ultra-high molecular weight polyethylene (UHMWPE) matrix as well as to develop polymer-polymeric composites with improved tribological characteristics, the structure, mechanical properties and wear resistance of UHMWPE mixtures with elasticizing block-copolymer PA-b-LLDPE (UHMWPE + PA-b-LLDPE) was investigated under dry sliding friction. Applied aspect of the study is related to the selection of commercially available fillers being compatible with UHMWPE for manufacturing anti-frictional extrudable nanocomposites. It is shown that as compared with pure UHMWPE mechanical properties (ultimate strength, value of elongation at failure) do not vary substantially, but the wear rate under dry sliding friction of polymeric composites UHMWPE + n wt.% PA-b-LLDPE is reduced only when block copolymer weight fraction is less than ≤ 5 wt.%. By the polymeric filling an important technological characteristic - specific pressure of extrusion (that is proportional to melt flow index) might be decreased. Permolecular structure and wear track surfaces of polymer-polymer composites UHMWPE + n wt.% PA-b-LLDPE was examined and numerically characterized.

“…In this case fixed abrasive particles cut the matrix and soft polytetrafluoroethylene cannot "protect" the matrix (grooves widths are comparable with that of pure UHMWPE specimens). Apparently, soft polytetrafluoroethylene under abrasive wear only facilitates sliding of abrasive paper along the specimen surface [5].…”

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.

“…Friction and wear are mostly governed by material type and roughness of friction surfaces [15]. Regardless of the combination of materials in the implant tribojoint (metal on metal or metal on polyethylene), abrasive wear prevails in these joints [16][17][18].…”

The article presents results of friction and wear tests of three piece systems of the intervertebral disc implant. The number of work cycles proved to have an effect on the coefficient of friction for polyethyl ene on metal and metal on metal tribojoints. In addition, for polyethylene on metal tribojoints, the effect of compressive force on the coefficient of friction was specified. The influence of working cycles on roughness changes of implant's working surfaces was analyzed. Based on the microscopic examination of the working surface of implants and morphology of the wear products, the wear mechanism was described. Studies were performed at the Laboratory of Surface Engineering and Tribology in the Metal Forming Institute in Poznan using a SBT 03 simulator.
