| 摘 要： | 通过表面铬钛渗层改性处理，可提高钢的表面硬度和耐磨性，从而提高工件的表面性能。对钢的铬钛共渗及其耐磨性进行分析研究，并与铬和钛的单渗层进行性能对比。结果表明，铬钛共渗层由混合铬碳化合物和TiC构成，这使得铬钛共渗层具有比铬和钛的单渗层更好的耐磨性。

| Abstract: | The microstructure of Cr-Ti coating was examined by electron probe scope, optical microscope and hardness meter. The room-temperature wear behavior of Cr-Ti coating was analyzed and compared with that of Cr coating, Ti coating and basis carbon steel. The results show that the Cr-Ti coating has better wear resistance than those of the Cr coating, Ti coating and the substrate. The wear resistance of Cr-Ti coating is mainly effected by the structure of the coating. The coating consists of complex compounds containing chromium carbides and TiC where Cr carbide exist mainly outside the coating and TiC exists mainly inside the coating. The complex compounds cause the coating have both advantages of Cr coating and Ti coating resulting in good wear resistance of Cr-Ti coating at room temperature. |
