WC particle reinforced cast iron matrix composites are manufactured by the vacuum infiltration technique.Their microstructures of the composites layers were analyzed.The erosive resistance of the composites layers were measured.The results show that WC particle reinforced cast iron matrix composites have good erosive resistance properties.Comparing with the high chromium cast iron,the erosive resistance of composites is 3～4 times beyond that of the high chromium cast iron.
