Characteristics of oxidative wear and oxidative mildwear

Abstract

Dry sliding tests were performed for 45, 4Cr5MoSiV1 steels and 3Cr3Mo2V cast steel at 200 and 400°C. The wears at 200 and 400°C are of oxidative wear characteristic due to tribo-oxides formed on worn surfaces. However, the wear at 200°C presents different wear behaviors and characteristics from the one at 400°C. The wear at 200°C is a typical oxidative mild wear, but the wear at 400°C is beyond oxidative mild wear, here called oxidative wear. The characteristics of oxidative mild wear and oxidative wear were clarified.
