This paper describes the mechanical strength of the cobaltless sintered WC which is suitable for the substrate of diamond-coated tool. Cobaltless WC is sintered under different sintering conditions by Spark Sintering. Then, its mechanical characters are evaluated by Rockwell hardness on the A scale and the bending strength. As a result, by selecting the proper sintering condition, the particle size is 1.0-1.4 μm, sintering temperature is 1800-1900°C, sintering pressure is 50 MPa and sintering time is 600 s, the hardness of the cobaltless sintered WC is improved to 98 (HRA), and the bending strength is improved to 1.3 GPa.
