Metallographic cross section through the laser gas nitride zone
TEM phase analysis of laser gas nitride Ti-6AL-4V
- Successful and reproducible laser gas nitriding generation of thick wear resistant surface zones on different titanium alloys (Ti-6Al-4V, cp-Ti, SP700)
- Understanding structural details, which determine their properties, allows the further development of processes to manufacture crack-free surface zones
- Reducing or avoiding the formation of titanium nitride opens up the possibility to achieve high long-term fatigue resistance, which makes the process applicable to cyclically highly loaded parts
