摘要(Abstract)：

分别采用Metco 130粉末及纳米结构Al2O3-13%TiO2可喷涂粉末通过等离子喷涂技术在Ti-6Al-4V(TC4)钛合金表面制备了喷涂态涂层,并利用CO2激光器对涂层进行了激光重熔。采用光学金相显微镜(OM)和扫描电镜(SEM)等分析手段研究了激光重熔前后涂层的微观组织,并采用压痕法和划痕试验研究了涂层的结合状态和划痕破坏失效行为。在界面附近进行破坏性压痕试验表明,两种喷涂态涂层与基体的界面处都产生了裂纹,而激光重熔涂层与基体的界面可保持完好。划痕试验表明,重熔涂层的破坏程度明显低于喷涂态涂层,喷涂态涂层的划痕破坏形式表现为较严重的脆性断裂和剥层破坏,而重熔涂层主要为局部脆性断裂。

关键词(KeyWords)： 钛合金;纳米涂层;等离子喷涂;激光重熔;划痕法
