| 摘 要： | 采用Ｍｏ，Ｗ，Ｃｕ合金铸渗灰铁件，可以提高其表面的硬度和耐磨性。研究表明，灰铁经过铸渗钼、钨铜合金后，在表面形成厚度为１．５ｍｍ的铸渗层，再经过短时间的高温加春扩散层厚度可达６ｍｍ，表面硬度明显提高，耐磨性是未经铸渗处理的２００％。

| Abstract: | The surface hardness and wearability of grey cast iron can be improved by casting integrated with surface alloying with Mo, W and Cu. Testing results show that after the process, a 1 5 mm thick alloyed surface can be obtained . After heating under a high temperature for a short time, the alloyed layer can be thickened to 6 mm. The surface hardness of the material is higher and its wearability is about twice of the original. |
