Tungsten carbide particles reinforced iron-based surface composites were obtained by vacuum negative pressure process. The microstructure of the composite layer was analyzed. The erosion-wear resistance of the composite layer was also investigated under the actual conditions. The results show that tungsten carbide particles reinforced iron-based surface composites have good microstructure and excellent erosion and abrasion resistance. Compared with high-chromium cast iron, the corrosion resistance is 3 to 4 times that of high-chromium cast iron
