Tungsten carbide button As the grain of the alloy continues to refine, the nanocrystalline cemented carbide gradually enters the field of view of researchers. Due to tungsten carbide button small grain size, large specific surface area and strong surface reactivity, it has some excellent properties while improving the hardness and strength of the alloy. Therefore, refining the cemented carbide grains to the nanometer level to achieve the effect of high hardness and strength has become the daily standard and direction of many researchers. PoratR et al. prepared 84% WC+15Co+1.0VC cemented carbide with three different particle size WC powders respectively. The results show that the nanocrystalline cemented carbide has the best performance. Feng Guolei et al. applied nanomaterials to the sintering formula of cemented carbide ball teeth. The results show that the required sintering temperature is significantly reduced. The hardness, wear resistance, strength and single tooth impact toughness of cemented carbide balls have different degrees. Increased, so tungsten carbide button service life is extended and production costs are reduced.
