Tungsten Carbide Cutting Tools Nanocomposite Reinforced

Tungsten carbide cutting tools nanocomposite reinforced refers to that join nanoparticles in fine grain carbide matrix, reinforced tungsten carbide cutting tools nanocomposite reinforced can improve the material properties of tungsten carbide cutting tools.

Mechanisms of tungsten carbide cutting tools nanocomposite reinforced are as follows: nanoparticles dispersed in a matrix material of tungsten carbide cutting tools having dispersed toughening effect. When the addition of nanoparticles in a matrix material particles in the matrix material by stretching the tissue transverse cross-section contraction effect, but to achieve the same substrate transverse shrinkage, you have to increase the longitudinal tensile stress, so you can make more material consumption more energy, play a toughening effect.

In addition, the dispersed cemented carbide substrate material carbide nanoparticles can inhibit grain growth during the sintering process, integrated to improve the mechanical properties of tungsten carbide cutting tools.
