摘 要: 利用雙層輝光離子滲金屬技術(shù)在鈦合金Ti6Al4V表面進(jìn)行合金化，形成均勻、 致密、 厚度為9.4μm的鈦鉬合金滲層。 表面硬度提高3倍左右， 達(dá)到1050Hk。 采用球盤磨損試驗(yàn)機(jī)考察了鈦合金Ti6Al4V表面滲鉬層和Ti6Al4V鈦合金的摩擦性能, 得出該合金表面滲Mo后雖然摩擦因數(shù)略微增大， 但耐磨性提高100余倍； 通過對磨損形貌的分析可知， 表面滲Mo合金層磨損機(jī)制主要表現(xiàn)為粘著及少量微切削。

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.
