Wear behaviour of SAE 4340 steel in comparison with single test specimen

Abstract

This study addresses the progressive damage of a surface/specimen/component caused by another substance in relative motion. This could cause the change in geometry, dimensions of the part which loses the practical functionality. So, an attempt was made to study the wear behavior of SAE 4340 steel using a pin-on-disc wear test machine at different loading, test speed, and time. Two cases viz. (1) single steel specimen, (2) multiple specimens were considered for the wear test and the obtained wear (µm), and frictional force (N) was compared.
