Abstract

The effect of silicon content (~2–6 wt%) on the wear behavior of a series of stainless steels is investigated using ball-on-disc wear test. The fractions of different phases and their deformation behavior considerably influence the wear behavior. The enhanced wear resistance of the steels with increased Si content is attributed to the improved hardness, increased fraction of ferrite phase, better strain hardening response, and grain refinement. Moreover, lenticular deformation of the austenite in the subsurface of worn-out zone parallel to the motion of the counter body (Si3N4 ball) serves cushioning effect by filling the cracks and preventing its growth during wear. This mainly attributes to the highest wear resistance in ~6 wt% Si-containing stainless steel.
