摘　　要：将WC与WC-6Co复合粉末采用XRD、SEM、ICP及激光粒度仪对粉末的物相、晶粒度、成分及粒度进行对比,结果表明:两种粉末的物相纯净,粒度分布均匀,杂质元素含量各有千秋,WC-6Co复合粉晶粒度为0.2μm。然后将制备WC与WC-6Co复合粉末的工艺流程、制备方法进行对比,可以看出:WC-6Co复合粉末的生产工艺流程短、设备简单、组元成分分布均匀。最后将WC与WC-6Co复合粉末制备超细硬质合金的性能进行对比,结果表明:WC-6Co复合粉末制备的超细硬质合金比WC和Co粉混合制备超细硬质合金硬度高,强度低。Using XRD,SEM,ICP and Laser Particle Size Meter to compare the phase,grain size,composition and particle size of WC and WC-6 Co composite powder,the results show that:the phase purity,grain size uniformity and impurity element content are different,the WC-6 Co composite powder grain size is 0.2 μm. While compare the production process,producing method and properties,the results show that:WC-6 Co composite powder has shorter production process,more simple equipment and more homogenous element distribution. WC-6 Co composite powder has higher hardness and less strength than the WC and Co powder mixture.
