Improvement of Wear-resistance of Titanium Nitride Duplex Coating by Control of Crystal Orientation

采用HCD离子镀方法制备了两种不同膜层特性的TiN复合涂层：一种是新开发的(111)强取向TiN薄膜，另一种是(111)和(200)择优取向的普通TiN薄膜。与铝合金的滑动磨损试验表明，氮化膜的磨损模式为只有切屑，没有划痕，从而缩短了膜层的使用寿命。N涂层的膜寿命约为C涂层的两倍。

Two kinds of titanium nitride(TiN) duplex coatings with different film characteristics were prepared by HCD ion plating : a newly developed TiN film with a strong(111) orientation and an ordinary TiN film with(111) and (200) orientations. From the sliding test against an aluminum alloy, it was revealed that the N-coating shows a wear mode with only chipping, with no scratching, which shortens the film life. The film life of N-coating is about twice as long as C-coating.
