Widely used for sealing surfaces or rings, it has the characteristics of wear resistance, high strength, high thermal conductivity, and small thermal expansion coefficient. Among all hard surface materials, it is the best material to resist thermal shock. Grinding and polishing are important processes for mechanical sealing surfaces and sealing rings. The mechanical seal end face and sealing ring come into contact with the grinding wheel in a moving manner. By removing the extremely thin surface of the mechanical seal end face and sealing ring, high precision can be achieved. Grinding and polishing improved the organization of the mechanical seal end face, forming a friction resistant sealing end face. Grinding and polishing reduce the friction of the sealing surface, increase the surface energy of the sealing surface, and enhance the corrosion resistance and polishing performance of the sealing surface.
