Silicon carbide-diamond multiphase ceramic grinding ring material and preparation method thereof
The invention discloses a silicon carbide-diamond multiphase ceramic grinding ring material and a preparation method thereof. The preparation method comprises the following steps: respectively preparing silicon carbide, carbon and boron carbide or silicon carbide, yttrium oxide, aluminum oxide and diamond into slurry; mixing the two kinds of slurry with diamond slurry respectively to form multi-phase composite slurry of silicon carbide, carbon, boron carbide and diamond or silicon carbide, yttrium oxide, aluminum oxide and diamond; drying the multi-phase composite slurry to obtain silicon carbide-diamond multiphase composite powder; preparing the composite powder into a silicon carbide-diamond ceramic sealing ring biscuit; and making the silicon carbide-diamond multiphase ceramic sealing ring biscuit prepared into a ceramic sealing ring blank through a pressureless sintering method, and then, making the ceramic sealing ring blank ground into the pressureless sintered silicon carbide-diamond multiphase ceramic mechanical sealing grinding ring according to requirements. The performance of the prepared silicon carbide-diamond sealing grinding ring is greatly improved, and particularly the heat conductivity coefficient, the hardness, the bending strength and the reliability performance are improved.
