Titanium alloys are applied in oil and gas development and transportation to improve conditions because of their high specific strength and corrosion resistance. However, the disadvantage of poor wear resistance has become an obstacle to developing titanium alloys. The friction and wear properties of pure titanium TA3 and titanium alloy TA10 were tested under different loads and different friction forms using a reciprocating friction and wear tester. Moreover, the erosion resistance of pure titanium TA3 and titanium alloy TA10 was studied using a gas-solid erosion tester. The results show that the wear rate of TA3 and titanium alloy TA10 increases with increasing friction load. Under a load of 50 N, the mass losses of TA3 under dry friction and wet friction were 0.0013 g and 0.0045 g, respectively, while the mass losses of TA10 were 0.0033 g and 0.0046 g, respectively. While the load increased to 70 N, the mass loss of TA3 was even greater, reaching 0.0065 g, and the mass loss of TA10 was 0.0058 g. The wear forms of TA3 and TA10 include abrasive wear, adhesive wear and oxidation wear. The joint action of various friction forms leads to the loss of materials. Under the simulated working conditions, the erosion rates of TA3 and TA10 were 1.01 × 10 g/s and 0.94 × 10 g/s. The erosion mechanism is the same, including plowing, indentation and cracking.
钛合金因其高比强度和耐腐蚀性而被应用于石油和天然气开发及运输领域，以改善工况。然而，耐磨性差这一缺点已成为钛合金发展的障碍。使用往复式摩擦磨损试验机，在不同载荷和不同摩擦形式下测试了纯钛TA3和钛合金TA10的摩擦磨损性能。此外，使用气固冲蚀试验机研究了纯钛TA3和钛合金TA10的耐冲蚀性。结果表明，TA3和钛合金TA10的磨损率均随摩擦载荷的增加而增大。在50 N载荷下，TA3在干摩擦和湿摩擦条件下的质量损失分别为0.0013 g和0.0045 g，而TA10的质量损失分别为0.0033 g和0.0046 g。当载荷增加到70 N时，TA3的质量损失更大，达到0.0065 g，TA10的质量损失为0.0058 g。TA3和TA10的磨损形式包括磨粒磨损、粘着磨损和氧化磨损。各种摩擦形式的共同作用导致材料损失。在模拟工作条件下，TA3和TA10的冲蚀率分别为1.01×10 g/s和0.94×10 g/s。冲蚀机制相同，包括犁削、压痕和开裂。
