对铸铁经硼砂盐浴渗钒后的渗层组织、耐磨性及经不同方式冷却后的冲击韧性进行了研究。结果表明：铸铁的碳化钒层整齐、均匀、连续，具有较高的硬度和耐磨性，其空冷组织具有最好的强韧性
The infiltration layer structure, wear resistance and impact toughness after different ways of cooling were studied on cast iron infiltrated by borax salt bath. The results show that the vanadium carbide layer of cast iron is neat, uniform and continuous with high hardness and wear resistance. The air-cooled microstructure has the best toughness
