针对钛合金耐磨性差的问题,利用WC颗粒与TA15钛合金粉末混合采用激光表面合金化技术在TA15钛合金表面成功制得以溶入W元素的β-Ti为基体、初生及共晶TiC/(TiW)C为增强相的表面改性层。结果表明,改性层由于钨元素与碳元素的添加,显微硬度得到提高,耐磨性能提高了2～3倍。TiC/(TiW)C硬质增强相为提高改性层的耐磨损性发挥了重要作用。 In order to solve the problem of poor wear resistance of titanium alloy, the microstructure of TA15 / Ti15 / Ti alloy was studied by using laser surface alloying (TA15) TiW) C is the surface modification layer of the reinforcing phase. The results show that the modified layer due to the addition of tungsten and carbon elements, microhardness is improved, wear resistance increased by 2 to 3 times. TiC / (TiW) C hard reinforcement phase to improve the wear resistance of the modified layer has played an important role.
