Wear behaviors of 3Cr2W8V and GH4169 with H70, including surface property, wear performance and friction work, were investigated. 3Cr2W8V and H70 friction pair suffered severer wear and surface damage than GH4169 and H70 friction pair. The wear process had an impact on GH4169 subsurface hardening, but no effect on 3Cr2W8V. Heat energy was a proportion of the total friction work, and 3Cr2W8V consumed...
