Abstract Taking ER8 wheel steel rim material as research object, it was nitrocarburized at 570℃, and then 4 kinds of untreated samples and nitrocarburized samples were tested by MMU-5G high temperature friction and wear tester. Friction and wear experiments in different temperature ranges (25℃, 300℃, 400℃, 500℃). The thickness of the layer was characterized by the microhardness of the section. The structure, composition and morphology of the co-infiltrated layer were observed and analyzed by laser confocal microscopy (VK-9710) and XRD. The wear properties and roughness of the two samples were observed. The degree and wear scar morphology were recorded and analyzed. The results showed that the surface microhardness of the sample increases significantly after nitrocarburizing; the nitrocarburizing significantly enhances the wear performance of the material when the ambient temperature is lower than 400℃, and the nitrocarburizing at 400℃ and above the wear reduction effect of ER8 wheel steel material is very limited; the wear form is mainly abrasive wear, adhesive wear and oxidative wear, and the untreated sample has abrasive wear in various temperature ranges between 25℃ and 500℃. Abrasive wear of infiltrated samples mainly exists at 25℃ and 500℃, while oxidative wear and adhesive wear of both are mainly present in high temperature environment (300—500℃),where the adhesive wear increases with the temperature rise to 500℃.
