| Research Abstract |
We examined low-temperature plasma nitriding in plasma sprayed SUS 316L coating to enhance wear resistance by forming an expanded austenite (known as S-phase) as supersaturated nitride. The S-phase on the sprayed coatings had almost same thickness as the one on bulk stainless steels when plasnla spraying Parameters, powder size and electrical power of the plasma torch, were optimized. In the result, the wear resistance of the nitrided SUS 316L coatings improved considerably. And more, low-temperature plasma carburizing and combined treatment of carburizing and nitriding were also examined to confirme thickning S-phase and improving distribution hardness.
