利用优化的涂覆铸造工艺，在灰铸铁表面复合WC增强相／高铬铸铁耐磨材料的基础上，对复合材料的磨粒磨损特性进行了试验研究。结果表明，与淬火态65Mn钢和45钢相比，复合材料的耐磨性提高幅度较大；但复合材料中的增强相含量有一最佳值，因只有增强相与高强度基体结合牢固，才能充分发挥出增强相抵抗磨粒犁削的潜力。
Based on the optimized cast coating process, the abrasive wear characteristics of the composites were studied on the basis of WC reinforced phase / high chromium cast iron wear-resistant materials on the surface of gray cast iron. The results show that compared with quenched 65Mn steel and 45 steel, the wear resistance of the composites increases greatly; however, the content of the reinforcing phase in the composite material has an optimum value. Only when the reinforcing phase and the high strength matrix are firm, Give full play to enhance the phase resistance abrasive grain plowing potential.
