ABRASIVE WEAR BEHAVIOR OF NITRIDED TEXTURED TITANIUM
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.
