项目摘要

The percussive duration and detached duration of coating film of the coating materials used under triborogical condition are investigated system atically. The way to get the coating film or thin film layers and materials were PVD method such as sputtering, ion plating, ionplanting, CVD method sucb as thermal CVD, Plasma CVD, diffusion like chromaizing and splay coating.It has been crarified that the percussive duration are much affected and depended on the base materials chose for coating materials and film thickness as well.From above results, it is dear that the ways to make the coating film to be adapted as practical performance. Furthermore, adhesive condition in the interface of both materials is so important that the binding strength between a coating material and base metal were invertigateed through the scratch tester. The some results that the friction became larger with small diameter of indenter under low load and with the added relatively large load because the penetrative break of coating film and the direct contact of the indenter edge to base metal as well were obtained through scratch testIt was crarified that in case of the easy break down of a coating film the materials reaches to critical failure owing to rising up friction.On TiNC coating film and TiN coating film the coating material is easily followed to base metal deformation. From the above result PVD method is much superior than the other methods on the point of a strength of film adhesion But in general the detachment of film is not remarkable.

系统地研究了摩擦条件下涂层材料的冲击时间和涂层脱落时间。获得涂层或薄膜层和材料的方法有PVD法如溅射、离子镀、离子种植、CVD法如热CVD、等离子CVD、扩散法如镀铬和展开涂层。研究表明，冲击时间的长短与涂层材料的基材选择和膜层厚度有关。根据以上结果，提出了使涂膜适应实际性能的方法。此外，两种材料界面的粘合状况非常重要，因此通过划痕试验研究了涂层材料与母材之间的结合强度。通过划痕试验得出了在低载荷下，由于涂层的穿透性断裂和压头边缘与母材的直接接触，压头直径越小，载荷越大，摩擦也越大的一些结果，说明在涂层容易破裂的情况下，材料由于摩擦上升而达到临界失效。在TiNC涂布膜和TiN涂布膜上，涂布材料很容易引起母材变形。从以上结果来看，PVD法在膜的粘附强度上明显优于其他方法，但总体上膜的剥离效果并不显著。
