摘　　要：牙用钛合金 TC4 ,使用渗氮表面技术处理。对强化层进行人工唾液润滑工况下往复式滑动摩擦磨损的动态试验。采用显微硬度、轮廓深度、XPS、显微镜观察等研究磨损机理。结果表明 ,钛合金 TC4表面氮化处理后 ,摩擦学性能、耐磨性得以提高。其磨损机理表现为粘着磨损。Titanium alloy material (TC4) samples were treated with nitriding technique. The dynamic friction and wear behavior of the modified layer were examined on a reciprocating sliding rig in artificial saliva. Microhardness, depth profile and wear mechanisms were investigated by means of MVK H12, TALYSURF6, XPS and microscopy. The results demonstrate that after being treated with nitriding technique the titanium alloy material(TC4) has better tribological behavior and up graded wear resistance.The wear mechanism involves adhesion.
