Abstract：Using XRD，SEM，ICP and Laser Particle Size Meter to compare the phase，grain size，composition
and particle size of WC and WC-6Co composite powder，the results show that：the phase purity，grain size uniformity
and impurity element content are different，the WC-6Co composite powder grain size is 0.2 μm. While compare
the production process，producing method and properties，the results show that：WC-6Co composite powder
has shorter production process，more simple equipment and more homogenous element distribution. WC-6Co composite
powder has higher hardness and less strength than the WC and Co powder mixture.
