英文摘要	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 more energy than GH4169 during temperature rise. From the numerical calculations, 3Cr2W8V had a more concentrated heat distribution and produced more wear than GH4169. Ultimate tensile strength (sigma(UTS)) and uniform elongation (epsilon(UE)) were considered to evaluate the wear resistance of two materials, and GH4169 had a higher sigma(UTS) X epsilon(U)(E) value and lower wear degree. In conclusion, the wear mechanism of GH4169 is adhesive wear, and 3Cr2W8V is a combination of abrasive and adhesive wear. Cooling can reduce the wear volume for GH4169 due to good thermal conductivity. The results show that GH4169 is more reliable for the tool material, with a better wear resistance under dry rolling condition.
