In order to improve the anti-friction and anti-wear performances of titanium and expand its application in aerospace and aircraft area, a commercially pure titanium grade 2 (TA2) was chosen and treated by compositing surface treatment. Dimple textures were prepared on the titanium surface by laser surface texturing (LST), and then the textured titanium was treated by ion nitriding. Tribological behaviors of the textured titanium and nitrided textured titanium were investigated under abrasive wear on a tribo-tester. The result shows that the anti-friction and anti-wear properties of textured titanium can be greatly improved by 47.1% and 79.3% after nitriding treatment, respectively. In addition, the dimple density has a significant effect on anti-friction and anti-wear behaviors.

氮化织构钛的磨损性能

为提高钛的减摩抗磨性能，扩大其在航空航天领域的应用，选用商业纯钛2级（TA2）进行复合表面处理。通过激光表面织构（LST）在钛表面制备凹坑织构，然后对织构钛进行离子渗氮处理。在摩擦测试仪上研究了织构钛和氮化织构钛在磨损下的摩擦学行为。结果表明，经氮化处理后织构钛的减摩和抗磨性能分别可大幅提高47.1%和79.3%。此外，凹坑密度对减摩和抗磨性能有显着影响。
