Study on VC Reinforced Iron Matrix Surface Composite Camshafts Fabricated by Cast-sintering

摘要: 利用铸造、粉末冶金方法制备了表面复合材料凸轮轴,并应用X射线衍射仪(XRD)、扫描电镜(SEM)、微区成分分析(EDS)对该表面复合材料的微观结构进行了分析,结果表明该表面复合材料复合层是VC颗粒增强铁基复合材料,并与基体实现了冶金结合。对凸轮轴表面复合层的性能进行了测试,测试表明该复合材料具有良好的耐磨性能及高温抗氧化性能。

Abstract: surface composite camshaft was prepared by casting and powder metallurgy,and the microstructure of this surface composite material was analyzed by XRD,SEM and EDS. The results show that the surface composite layer is VC particle reinforced iron matrix composite,and the composite has a good metallurgical bonding with the matrix. The properties of the camshaft surface composite layer were tested,and the results show that the composite material has good wear resistance and high-temperature oxidation resistance.
