Abstract—

Tribotechnical characteristics of Ti6Al4V titanium alloy–ultra-high-molecular-weight polyethylene (UHMWPE) under high loads have been investigated depending on friction conditions. Friction pairs consisting of blocks made of polyethylene with constant machined surface parameters used as the samples and rollers made of titanium alloy having different surface roughness used as the rollers have been studied under dry processing or under processing with emulsion under cooling. Distilled water and counter-bodies Simulated Body Fluid (SBF)) have been used as lubricants. Based on the results of the measurement performed for momentary friction coefficients, friction temperature, and wear rate, as well as on the analysis of worn surface topography for blocks and rollers, it has been found that the best tribotechnical characteristics can be achieved using rollers with a high surface roughness and SBF as the lubricant.

Ti6Al4V钛合金-超高分子量聚乙烯摩擦副的摩擦学特性

摘要—

根据摩擦条件，研究了Ti6Al4V钛合金-超高分子量聚乙烯（UHMWPE）在高载荷下的摩擦学特性。在干法加工或在冷却条件下用乳液加工的条件下，对由摩擦系数对组成的摩擦副进行了研究，摩擦副由具有恒定加工表面参数的聚乙烯制成的块用作样品，由具有不同表面粗糙度的钛合金制成的滚子用作辊。蒸馏水和人体模拟体液（SBF）已用作润滑剂。根据瞬时摩擦系数，摩擦温度和磨损率的测量结果，以及对滑块和滚子的磨损表面形貌的分析，
