| 摘 要： | 采用等离子表面渗氮技术对TD3合金进行渗氮处理,并对渗氮层显微组织、相组成及硬度进行检测。对渗氮前后TD3合金分别进行常温(25 ℃)及600 ℃的摩擦磨损试验,分析摩擦温度对其摩擦因数、磨痕形貌及磨损率的影响;结果表明,离子渗氮处理后TD3合金表面形成一定厚度的氮化物层,氮化物层在降低摩擦因数的同时,显著降低了TD3合金的磨损率,温度由25 ℃升至600 ℃时,磨痕形貌变化较大,摩擦因数及磨损率也有一定幅度的增加。

| Abstract: | TD3 titanium alloy was nitrided by plasma surface nitriding technology, and microstructure, phase composition and hardness of the nitrided layer were tested. The friction and wear experiments of the TD3 alloy before and after nitriding were carried out at room temperature (25 ℃) and 600 ℃ respectively, and the effect of friction temperature on the friction coefficient, wear scar morphology and wear rate of which were analyzed. The results show that after plasma nitriding, a certain thickness of nitrided layer is formed on the surface of the TD3 alloy. While reducing the friction coefficient, the nitrided layer significantly reduces the wear rate of the TD3 alloy. When the temperature rises from 25 ℃ to 600 ℃, the wear scar morphology changes greatly, and the friction coefficient and wear rate also increase to a certain extent. |
