【摘要】对添加VC的TiB2 基硬质材料进行了研究。通过实验测定了硬度、横向断裂强度、高温强度以及耐磨性等性能 ,通过观察SEM照片研究了VC对TiB2 基硬质材料组织结构的影响。综合各种指标 ,我们确定在TiB2 -Fe-Mo硬质材料中VC的最佳添加量为 0 .5 %。更多还原

【Abstract】 Effects of VC addition on structure and properties of TiB 2 hard materials were investigated by measure-ment of hardness,transverse rupture strength,high temperature strength,wear resistance etc and observation of SEM photos. The results show that the VC optimum content in TiB 2 Fe Mo hard material is 0.5%.更多还原
