The main aim of our project is to increase the lifetime of bearing materials particularly EN31 steel which is used in manufacturing of Ball bearings, Spinning tools, Beading Rolls, Punches and dies. EN31 is a quality high carbon alloy steel. Increase in the lifetime of a material is done either by alloying with appropriate materials before its producing. This project makes an attempt to enhance the lifetime of EN31 steel by modifying the surface through heat treatment and coating process. Wear tests were performed on untreated and treated material with the help of pin on disc equipment. The Coefficient of Friction, the wear rate and wear coefficient were determined on pins.

Nitriding, Pin on Disc, Wear rate.
