【Abstract】 Ceramics are increasingly considered to produce cutting tools,wear parts and structurla components because of their thermomechanical properties,low density and excellent corrosion compared with metals.However,the intrinsic brittleness of ceramics has limited their use in critical load bearing structural components.A variety of method for improving toughness of high reliable structural ceramics was reviewed.Finally,future directions were discussed更多还原
