Study of the Physical and Mechanical Properties of Sintered Nitrided Austenitic Stainless Steel Powder

This project presents the work on high temperature gas nitriding of austenitic stainless steel powder. Nitriding is one of the methods used in surface engineering to increase the hardness and wear resistance of austenitic stainless steel. Normally nitriding is done at bulk of steel but for this project different technique is chosen where nitriding is done on the powder of the austenitic stainless steel. The problem is when nitriding bulk austenitic stainless steel; the solid state diffusion will take place only at low case depth. However by nitriding the powder of austenitic stainless steel, the nitrogen content will be extended to the core of the steel.
