This study investigated the fabrication method of single crystal diamond∕cemented carbide composite cutter for rock drilling. By adopting just right amount of phosphorus and nickel as sintering aid, the consolidation of diamond∕WC-Co composite was achieved by hot pressing the blended powder in vacuum at 1060°C for 5 min with a pressure of around 20MPa. The sintering temperature was relatively low so that the serious degradation of diamond grit was avoided. The hardness, wear ratio and impact strength of the composite were tested and the results indicated that the composite can meet the demand for rock drilling. The indoor drilling experiments...
