The effect of wear and corrosion on internal crystalline texture of carbon steel and stainless steel

Abstract

Wear and corrosion wear involve mechanical and chemical mechanisms and the combination of these mechanisms often results in significant mutual effects. In this research, wear performances, and texture changes of carbon steel AISI 1045 and stainless steel AISI 304 under simultaneous wear and corrosion were investigated and the results were compared with those obtained from dry wear tests. 3.5 wt.% NaCl solution was used as the corrosion agent and a pin-on-disk tribometer was employed to perform wear and corrosion wear tests. Wear tests of carbon steel and stainless steel samples have shown smaller weight losses and lower friction coefficients in the presence of corrosive environment. Texture investigations of the worn samples have shown texture changes after wear and corrosive wear tests. In worn carbon steel samples after dry wear test 〈0 1 1) 〈1 0 0〉 Goss texture and {1 1 1} gamma fiber component were developed in initially random oriented samples, whereas under corrosive wear conditions, {1 1 1} 〈 0 1 1 〉 fiber texture and {0 0 1} 〈 1 1 0 〉 cube texture were obtained. In stainless steel samples, {1 1 2} 〈 1 1 0 〉 texture component were observed under both dry and corrosive wear conditions, in initially random samples.
