中文摘要:
      采用简化预处理辅助化学沉积方法制备了WC-Ni复合粉体,结合压制烧结方法获得了不同Ni成分的WC-Ni复合材料。通过FESEM. EDS 和XRD检测手段研究分析了原始WC粉、WC-Ni复合粉体和WC-Ni复合材料的表面形貌和断口特征。研究了不同Ni含量对WC-Ni复合材料组织性能的影响规律。实验结果表明,Ni颗粒均匀包覆在WC粉体表面,WC-Ni复合材料具有细小均匀的晶粒分布;随着Ni含量的增加,WC-Ni复合材料的抗弯强度增加,硬度基本保持不变,断口形貌表现出穿晶断裂特征。

英文摘要:
      WC–Ni composite powders have been prepared by electroless plating with a simplified chemical method. The original WC powders, pretreated WC powders, WC–Ni powders and surface of WC–Ni composites, as well as their fracture cross-sections, were analyzed by FESEM. EDS and XRD were performed to identify the composition. Different contents of Ni doping WC composites were investigated. The relative density and properties of the WC–Ni composite were also discussed. Results show the WC powders were uniformly covered by Ni coatings. After powder metallurgy, the fabricated composites performed a well-dispersed surface morphology. And the increasing Ni content enhanced bending strength without reducing excessive hardness, which involved the uniformity of Ni phase in the crystal boundary of WC. Trans-granular fractures were observed on the surface of the WC–Ni composite because of the uniformity of binder phase (Ni).
