Sliding wear tests were performed for H13 steel and a cast steel under atmospheric conditions of 25, 200, and 400°C. XRD results identify that oxidative wear prevailed for the steels during sliding at 200-400°C. However, the oxidative wear at 200°C presented entirely different wear behaviors from the one at 400°C. With an increase of load, the oxidative wear at 200°C exhibited slowly increased and lower wear rates, despite relatively less tribo-oxides. On the contrary, although there were more tribo-oxides, the oxidative wear at 400°C presented rapidly increased and higher wear rates. The former oxidative wear could be classified into mild wear; the latter one fell beyond mild wear. The two types of oxidative wear universally existed; their discrepancies were mainly attributed not to the tribo-oxides, but to the extent of softening and deformation of substrate. Hence, we suggested that the two types of oxidative wear should be distinguished in the coming research, and were termed oxidative mild wear and oxidative wear, respectively.
