Nano-SiCp Modified Tungsten Carbide Cutting Tools

Application of nano powder composite can improve hardness, toughness and other comprehensive performance of tungsten carbide cutting tools which is an important research direction of tungsten carbide cutting tools.

Mechanical properties hardness and relative density of nano-SiCp modified tungsten carbide cutting tools are better than tungsten carbide cutting tools free of SiCp. This is due to nano SiCp in nano-SiCp modified tungsten carbide cutting tools are mainly in the hard phase WC particles at grain boundaries, and play a role in pinning grain boundaries and the grain refinement. Intensity of tungsten carbide cutting tools is related to relative density.the higher the intensity, the presence tends to diffuse spheroidal form, the anti-chipping performance also increases. Flank wear area of Nano-SiCp modified tungsten carbide cutting tools will not fall off, showing a more stable abrasive wear.
