Wear Characteristics of AISI 310 Grade Stainless Steel Material by Carbonitriding Process

Abstract

The investigation on the microstructure and mechanical behaviour of steel AISI 310 has been carried out during a Carbonitriding process aiming to improve the wear performance. The comparison study was made to treated specimens with untreated sample. Carbonitriding is a viable technique to enhance the wear resistance of the stainless steel material. The present study focused in the direction of investigating the effect of microstructure, hardness and wear resistance of AISI 310 stainless steel material. In carbonitriding process the case depth was found to be from 13, 16.5 and 19 Microns which is treated 2 hrs, 4hrs and 6 hrs respectively. The combination action of strong adhesion, abrasion and severe plastic deformation are the primary reasons for the continuous material loss in the untreated specimens during testing. The Optical microscope, SEM analysis and wear test are conducted to find out the various results.
