摘要
The present invention relates to a method of adding a grain growth inhibitor of WC/Co cemented carbide, which comprises adding a water-soluble salt of V, Ta, or Cr component as a grain growth inhibitor, at the time of mixing water-soluble salts of W and Co during the initial production process of WC/Co cemented carbides. As a result, the present invention leads to the production of powder of homogeneous distribution of grain growth inhibitors, which in turn results in the enhancement of the mechanical properties thereof by effectively controlling the abnormal growth of WC during sintering in the production process of said cemented carbides.
