Abstract
High-performance powder metallurgy high-chromium iron-based alloy reinforced by nano-WC particles were prepared by high-energy ball milling combined with hot-press sintering. The effects of different temperatures of hot-press sintering and contents of WC reinforced phase on the friction and wear properties of the materials were studied by using the M-2000 Friction and Wear Tester under dry condition. The results show that the wear property of the material increases first, and then decreases with the growth of temperature of sintering and contents of reinforced phase. The alloy has the best wear property sintered at 1050 °C with 5wt.% WC reinforced phase. By comparing with NbC reinforced phase with similar mass fraction at 5%, finding that WC particles have more significant effect on reinforcing the wear
