| 摘 要： | 利用铸渗法制备了WC颗粒增强钢基表面复合材料,通过金相、扫描电镜等测试手段,重点研究了预制层中添加Ni粉对WC/钢基表面复合材料组织和界面的影响。结果表明,随着Ni添加量的增加,铸渗层中WC颗粒数目逐渐增多,复合层与基材的过渡趋于平缓,表面质量也趋于完好。同时,随着Ni添加量的增加,过渡层的变化逐渐趋向平缓,基体中马氏体、残余奥氏体及共晶碳化物的数量逐渐增加,并且复合层表层硬度呈现递增的趋势。

| Abstract: | WC particle reinforced steel matrix surface composites were successfully prepared by casting-infiltration method, and effects of nickel powder on microstructure and interface of WC/steel matrix surface composites were observed by OM (optical microscope) and SEM (scanning electron microscope) and EDS (energy dispersive spectrometer). The results reveal that with increasing in nickel powder addition, WC particles in infiltrated layer are increased, which results in the smooth transition between composite laye... |
