陶瓷和金属相比。具有硬度大、摩擦系数低、耐磨性好而成型与加工容易的特性。目前,由于从原料的制造、精选直到加工和制造的全过程都实现了科学管理。从而,更加提高了陶瓷的物理和机械性能。陶瓷轴承材料的研究也在各国得到发展。 Compared to ceramics and metals. With a large hardness, low coefficient of friction, wear resistance and easy molding and processing characteristics. At present, due to the scientific management from the manufacture of raw materials, selection until the entire process of manufacturing and manufacturing. Thus, the physical and mechanical properties of the ceramic are further enhanced. Research on ceramic bearing materials has also been developed in various countries.
