摘要
应用 SEM和 XRD研究了铸造烧结过程中 V8C7- Fe基表面复合材料组织结构的变化 ,用 MM2 0 0磨损实验机研究了 V含量对 V8C7- Fe基表面复合材料耐磨性能的影响。结果表明 ,随着含 V量的提高 ,表面复合材料的硬度越高 ,耐磨性能越好。
The variations of structure and composition of V 8C 7-Fe surface composites was studied with the help of MM200.The result showed that with the increase of the content of V,the hardness and the wear resistance of the surface composites all increased.
