Abstract
Austenitic stainless steel is limited to utilize directly in numerous industries on account of its low surface hardness. Hence, in this work, an effort has taken to enhance the surface hardness of austenitic stainless steel type AISI 316LN Stainless Steel (316LN SS) by Gas Nitride (GN) technique. The GN was done on 316LN SS at 520°C for 42 hours. The GN was done in two phases to limit the white nitride layer. The GN treatment enhances the surface hardness from 210 HV25g (untreated 316LN SS sample) to 1230 HV25g (GN treated sample). The GN treatment produces a thick and uniform nitride layer on the 316LN SS. The tribolgical test conclude that the GN layer on 316LN SS eliminates adhesion bonds at the contact points and show smooth surface even after 1000m sliding distance. Consequently, the GN treatment was not just reduce the friction and also formed an excellent wear resistance GN layer on the 316LN SS substrate.
