Abstract
Wear and fatigue are the serious concerns for engineering structures and components like turbine blades, crank shaft, thermal power plant, gears etc. An investigation on wear behavior of nitrided 13/4 martensitic stainless steel resulting from low temperature salt bath nitriding is presented in this work. 13/4 martensitic stainless steel was nitrided in salt bath at 500 °C. The nitrided layer thickness, hardness and erosion wear behavior of the treated material is studied. Results show that low temperature treatment produced a hard layer without forming chromium nitride precipitates, which is the greatest challenge during nitriding of stainless steels, thus kee** stainless properties of the steels intact. The slurry erosion behavior of nitrided steels shows that 4 hour nitriding resulted in minimum erosion.
