| Abstract: | The microstmcture,hardness and wear resistance of the ion-nitrided TiAI Based Alloy at high tempareture were studied. The result shows that the formed nitrogen scale consists of the Ti2AI,TiN and AITi3 compound layer and the transition layer. The study also indicates that the surface hardness and wear resistance of the samples are evidently improved by various nitriding processes. |
