采用激光熔覆工艺，通过原位置换结晶反应在Ｔｉ６Ａｌ４Ｖ基材上制备出碳化物颗粒增强复合材料熔覆层，发现复合材料由均匀弥散分布的ＴｉＣ颗粒及β－Ｔｉ基体构成，且与基材呈冶金结合．干摩擦下其磨痕及磨屑扫描电镜分析表明，激光熔覆层具有较高的耐磨性的原因是复合材料中均匀弥散分布的ＴｉＣ粒子具有良好的抗磨作用 The laser cladding process was used to prepare the carbide clad composite cladding layer by in-situ displacement reaction on Ti6Al4V substrate. The composite was composed of uniformly dispersed TiC particles and β-Ti matrix, Metallurgical combination. The results of scanning electron microscopy (SEM) and scanning electron microscopy (SEM) of wear scar under dry friction show that the reason why laser cladding layer has high wear resistance is that TiC particles dispersed uniformly in the composite have good anti-wear effect
