Abstract
为了研究Si含量对TiSiN涂层性能的影响,采用多弧离子镀技术在Ti6Al4V表面制备了不同Si含量(质量分数)的TiSiN涂层。利用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、电子能谱仪(EDS)、X射线光电子能谱仪(XPS)纳米压痕仪、摩擦磨损试验机表征其表面形貌、成分,力学性能及摩擦学性能。结果表明:随着靶材中Si含量的增加,涂层硬度从35GPa增加到42GPa。在TiSiN涂层中Si元素主要以Si3N4非晶态存在,形成了非晶Si3N4包裹TiN纳米晶结构。当靶材中Si含量为8%时,涂层在海水中的磨损率约为2.1×10-6 mm3/(N·m),此时涂层的摩擦性能最好
