为了提高钛合金的耐磨性，采用熔铸法制备了（TiC + TiB）体积分数分别为0、2、4、6、8和10%的原位钛基复合材料（TMCs）。结果表明，（TiC + TiB）增强体的弥散分布提高了TMCs的摩擦学性能，改善了TMCs抵抗表面剪切应力的能力。磨损过程中形成的稳定转移层降低了摩擦副界面的剪切强度，限制了摩擦副界面的直接相互作用，有效地提高了表面硬度和耐磨性。随着增强体含量的增加，磨损机制由严重的粘着磨损和氧化磨损逐渐过渡到轻微的粘着磨损、磨粒磨损和氧化磨损。
To enhance wear properties of titanium alloys,in situtitanium matrix composites (TMCs) were synthesized by a melting cast method with (TiC + TiB) volume fractions of 0, 2, 4, 6, 8, and 10%. The results indicated that tribological properties of TMCs were increased owing to the dispersed distribution of (TiC + TiB) reinforcements, which improved the ability to resist the surface shear stress. Moreover, the stable transfer layer formed during wear reduced the shear strength and limited the direct interaction at tribo-pair interfaces to enhance surface hardness and wear resistance effectively. Consequently, the wear mechanism appeared to transitioned from the severe adhesive and oxidative wear gradually to the slight adhesion, abrasive, and oxidative wear along with reinforcements content increased.
