摘　　要：根据机械密封对密封副材料的要求,综述了不同烧结方法制备的碳化硅材料的力学性能、耐腐蚀性能和摩擦学性能,由于碳化硅所具有的优异性能,作为密封材料可广泛应用于高压、高转速、高温、腐蚀介质、干摩擦以及含有固体颗粒的工况下,成为机械密封材料的理想选择。According to the requirements of the mechanical seal on the sealing materials,The properties of silicon carbide in the different sintering,include mechanical properties,corrosion resistance and tribological properties were reviewed. Since the silicon carbide has excellent performance as a sealing material,it can be widely used in high-pressure,high speed,high temperature,corrosive medium,dry friction and containing the solid particles on the operation conditions,and becomes ideal choice of the mechanical seal material.
