摘 要: 利用双层辉光离子渗金属技术在钛合金Ti6Al4V表面进行合金化,形成均匀、 致密、 厚度为9.4μm的钛钼合金渗层。 表面硬度提高3倍左右, 达到1050Hk。 采用球盘磨损试验机考察了钛合金Ti6Al4V表面渗钼层和Ti6Al4V钛合金的摩擦性能, 得出该合金表面渗Mo后虽然摩擦因数略微增大, 但耐磨性提高100余倍; 通过对磨损形貌的分析可知, 表面渗Mo合金层磨损机制主要表现为粘着及少量微切削。

Abstract:Ti-Mo alloyed layers, whose friction and wear behavior against GCr15 was investigated under dry sliding by comparing with that of Ti6Al4V alloy against the same counterpart under the same testing condition, can be produced on the surfaces of Ti6Al4V alloy by Xu-Tec process. The worn surfaces of the tested samples were observed with optical microscope, as an effort to analyze the wear mechanisms. It has been found that the Ti-Mo film has good wear-resistant behavior in sliding and its wear rate is 100 times less than that of Ti6Al4V.
