摘　　要：对耐磨材料的性能要求有硬度高,耐磨性好;冲击韧性好,不易损坏。钢铁中不同类型的碳化物,以MC型碳化物的硬度最高。获得大量均匀、弥散分布的MC型碳化物是新型高钒耐磨合金设计的目的,其耐磨性是高铬铸铁的3~7倍,并有良好的冲击韧性,在水泥、轧钢等行业得到了广泛应用。The performance requirements of wear-resisting material is high hardness and good abrasion resistance, good impact toughness and not easy to damage. MC type carbide in the different types of carbides in steel has the highest hardness. The purpose of the new type of high vanadium alloy composition design is to obtain a large number of uniform distribution and the dispersion of MC type carbide. The wear resistance of the material is 3-7 times higher than that of the high chromium cast iron, which has good fracture toughness, and is widely used in cement and steel rolling industries.
