Effect of microstructural evolution during dry sliding on the corrosion behaviour of martensitic stainless steel

In this study, the effects of cycle dependent wear on the consecutive corrosion behaviour of AISI 420 in 0.15 M NaCl solution were investigated to determine the influence of the tribological microstructure alteration on the electrochemical behaviour. The results revealed adhesion dominated wear at l...

Summary:In this study, the effects of cycle dependent wear on the consecutive corrosion behaviour of AISI 420 in 0.15 M NaCl solution were investigated to determine the influence of the tribological microstructure alteration on the electrochemical behaviour. The results revealed adhesion dominated wear at low cycle counts that led to the formation of a lamellar microstructure with delamination and enlarged Cr-depleted areas, resulting in a significant decline in pitting corrosion resistance. As the number of cycles increased, a transition of the wear mechanisms towards abrasion was observed. The progressive deformation allowed strong grain refinement and homogenization of the microstructure, which led to a significant increase in the pitting corrosion potential.
