| Abstract: | WC Particie reinforced high chromium cast iron matrix surface-layer composites have been prepared successfully of lining Plates of eject orifice. The three-body abrasive resistance of composites and effect of practical application have been investigated respectively.The resuts show that: the best volume fraction of particle is 52%,and interface is compact ,there are no defect such as inclusion?crack and so on.The three-body abrasive resistance of composites is 5.1 times higher than that of high chromium cast iron,the service life of lining plates is 3.5 times more than ones. |
