| Abstract: | A new preparing process of cast tungsten carbide particle/medium manganese steel surface composites is developed in this study. The infiltration process dynamics that metal melt entered particle layer is analyzed. The results show that sound surface composites can be obtained by using Cr Fe particles and rare earth alloy to improve infiltration property of the melting metal, common clay dry mould or CO 2 hardening mould. The physical model of infiltration depth of melting metal to particle layer agrees with the experimental results. |
