Wear Behavior of Carbon Steels

Abstract

The present work is concerned with study the wear behavior of 1020, 1060, and 1095 steels under different wear conditions, rotating contact speeds (500,850, and 1200 rpm) and normal contact loads (50,100,150 and 200 N) using pin on wheel wear testing machine. The prepared specimens were normalized to make sure that all types of steels are in the same structure. Wear testing results were recorded by measuring weight loss at different contact times (10, 20, 30, 60 and 90 min). The aim of this paper was to study the effect of normal loads and rotating speeds and their interactions on wear behavior of steels under various continuous sliding contact times. The presented relations between the volume loss and working conditions showed that low carbon steel had wear loss higher than other carbon content. In addition, results for all types showed that lower rotating speed had higher effect than other speeds and high normal load had higher effect than other loads. The highest volume loss was observed at high normal load and low rotating speed. And the relation between wear coefficient and working conditions was also observed that wear coefficient decreases as both normal load and rotating speed increase.
