The wear behaviour of heat-treated Ti-35Nb-7.2Zr-5.7Ta (TNZT) and Ti-35Nb-7.2Zr-5.7Ta-0.5B (TNZTB) alloys (all compositions are in wt%) was investigated in dry condition and in simulated body fluids. It has been found that there is no straightforward relationship between the wear rate and the microstructure. The hardness has no appreciable effect on the wear behaviour of these alloys. The presence of boron in the TNZT alloy deteriorates its wear properties. The wear rate of TNZT and TNZTB alloys in various media increases in the following sequence: dry condition < Hank's solution < bovine serum.
研究了热处理 Ti-35Nb-7.2Zr-5.7Ta（TNZT）和 Ti-35Nb-7.2Zr-5.7Ta-0.5B（TNZTB）合金（所有成分均为重量%）在干燥条件和模拟体液中的磨损行为。研究发现，磨损率与微观结构之间没有直接的关系。硬度对这些合金的磨损行为没有明显的影响。硼的存在会降低 TNZT 合金的磨损性能。在不同介质中，TNZT 和 TNZTB 合金的磨损率按以下顺序增加：干燥条件<Hank's 溶液<牛血清。
