Kinetics of Stainless Steel Material by Plasma nitriding Process for sustainable applications

Abstract

Implantation of ion at low temperature and nitriding through plasma process at low-temperature prevents the corrosion resistance in stainless steel material. The outcome of nitriding process is to form precipitation of CrN on the surface. For the current research work, plasma nitriding techniques are adopted to nitride AISI 304 at low-temperatures at 5hrs, 10hrs, 15 hrs. The enriched layers are formed with combine nitrogen lead to increase in surface hardness. Austenitic and duplex steels produce expanded austenite on the material surface. Behavior of wear was monitored by pin on disc tester. The case depth were monitored and compared with a sample which is not treated. The morphology of surface were monitored and compared with the electron microscopic images. Finally hardness measurements were carried out with Rockwell hardness tester.
