Problems solved by technology

[0002] Ceramic materials have the advantages of high melting point, high hardness, high wear resistance, high chemical stability, etc., but brittleness is its fatal shortcoming, which limits the application range of ceramic materials. Therefore, the strengthening and toughening of ceramic materials has always been an important issue for material scientists long term concern
[0003] In addition, for traditional structural ceramics, the increase in strength is often accompanied by a decrease in the fracture toughness of the material. The contradiction between the hardness and toughness of ceramic materials is also a major problem for ceramic materials, which limits its popularization and application.
