摘要
微弧氧化处理后的钛合金,表面形成的多微孔氧化膜可使其摩擦因数降低且耐磨性得到提高,但这还不能满足某些使用要求。在微弧氧化的基础上再利用脉冲偏压式磁控溅射技术在钛合金表面沉积氮化钛涂层。球盘磨损试验表明,与微弧氧化相比,其摩擦因数进一步降低且耐磨性进一步提高,这主要是沉积富钛氮化钛使氧化膜的微孔得到了部分或全封闭的覆盖。
Titanium alloy was duplicate treated by means of micro-arc oxidation and magnetron sputtering. The effect of the duplicate surface treatment on the wear resistance of the Ti alloy was investigated. It was found that a porous oxide film was formed on the surface of the Ti alloy after micro-arc oxidation, which contributed to decreasing the friction coefficient and increasing the wear resistance of the Ti alloy to some extent. The friction coefficient could be further decreased, while the wear resistance further increased when a titanium nitride coating was introduced onto the micro-arc oxidation layer of the Ti alloy making use of magnetron sputtering. This was because the pores in the micro arc oxide layer were partly or completely closed after the magnetron sputtering.
