The role of vacuum sintering of tungsten carbide mold mainly has the following aspects:
1. Improve hardness and toughness: Vacuum sintering is a method of sintering tungsten carbide powder into cemented carbide by using high temperature and high pressure. Through vacuum sintering, tungsten carbide powder can be fully sintered, thereby improving the hardness and toughness of cemented carbide. 2. Improve corrosion resistance: Sintering in a vacuum environment can reduce the residue of harmful substances such as impurities and oxides, thereby improving the corrosion resistance of cemented carbide. 3. Improve density and density: Through vacuum sintering, cemented carbide materials can be made to have higher density and density, thereby improving their mechanical properties and prolonging their service life.
4. Improve surface quality and processing performance: Vacuum sintering can eliminate residual stress and deformation, thereby improving the surface quality and processing performance of cemented carbide materials, and increasing the yield.
