Optimizing the Three-Body Abrasion Wear of Quenched and Tempered Steel

Abstract

The present study investigates the wear behaviour of Quenched and Tempered Steel (Hardox 400) under three-body abrasion wear testing conditions using dry sand rubber wheel testing rig under dry wear conditions at room temperature. Design of experiments approach using face centred design was used to investigate the correlations between resultant wear loss and input parameters (viz. Applied load, speed and flow rate of abrasives) using silicon carbide sand with 100–150 grit size. The results revealed that, among all the parameters studied, the load was found to be the most significant parameter affecting the wear rate followed by abrasive flow rate and the rotational speed of the rotating rubber wheel.
