| Abstract: | The plasma-nitration process of Ti-46.5Al-2.5V-1.0Cr alloys in ammonia has been investigated. Compared to the high temperature gas nitration, this progress is shortened by one fifth and the depth of nitrided case is increased by 2.5 times. It has been found that the specimen handled in 900 ℃×9 h can achieve its hardness to 1 097 HV and its depth of nitrided case can achieve more than 10 microns. Compared to the original alloy, the wear-resisting property is increased by 2.5 times. |
| Keywords: | TiAl based-alloys plasma-nitration micro-hardness layer's thickness |
