The hardness and fracture toughness of ceramic materials are the key factors affecting the wear rate, and the wear rate of ceramic materials with high hardness and fracture toughness is lower. In view of the goal of improving the hardness and fracture toughness of ceramic materials, compared with ordinary metals or plastics, wear-resistant ceramic rod have the following advantages: high hardness, high strength, good wear resistance, more than 100 times more than manganese steel, high temperature resistance, acid and alkali corrosion resistance, light weight, only half of steel, can greatly reduce the load of equipment.
