Article Preview

Cemented carbide tools are widely used in machining industry due to their superior properties. WC-Co composite cemented carbide tool materials reinforced with Ni and SiC nano particles were fabricated by using powder metallurgy followed by hot extrusion. Different modified mechanism (nano-SiCp modified,binder(Co, Ni) modified and Co electoless plating coated WC ) of WC-based cemented carbide tool materials were fabricated by using powder metallurgy followed by hot extrusion. Microstructure,mechanical and cutting properties were studied. The results show that the heat-resistance, as well as high-temperature behaviors (hardness, wear-resistance and obdurability ) ,can be improved by adding nano-SiCp on WC-based cemented carbide. Ni-Ti replaced Ni as binder can improve hardness and red-hardness of tool. Mechanical properties are enhanced due to Co as binder having more wettability on WC surface than Ni .
