采用射频磁控溅射技术在钢基体上沉积TiN、Ti（B，N）和TiB 2硬质涂层。溅射测定了涂层的结构、附着力、硬度、内应力和化学成分等基本性能。涂层已经测试了它们的摩擦学行为，通过无润滑销-盘模型磨损试验在环境大气下，以及在真空条件下。球轴承钢和高速钢制成的球已被用作销材料。据发现，占主导地位的类型的膜内的化学键合是一个重要的涂层性能方面的磨损行为在销盘测试条件下。结果表明，TiB 2薄膜在与钢的滑动接触中的益处有限。Ti（B，N）和众所周知的TiN是更有前途的涂层材料。
TiN, Ti(B,N) and TiB2hard coatings have been deposited on steel substrates by means of r.f. sputtering. The fundamental coating properties, such as the structure, adhesion, hardness, internal stresses and chemical composition, have been determined. The coatings have been tested with regard to their tribological behaviour by means of unlubricated pin-on-disc model wear tests under an ambient atmosphere as well as under vacuum conditions. Balls made of ball bearing steel and high speed steel have been used as pin materials. It was found that the dominant type of chemical bonding within the film is an important coating property with regard to the wear behaviour under pin-on-disc test conditions. It is shown that TiB2films are of limited benefit in a sliding contact against steel. Ti(B,N) and the well-known TiN are much more promising coating materials.
