Although the special nano-zirconia ceramic material for structural ceramic toughening has many superior properties, such as high temperature mechanical properties, chemical corrosion resistance, electrical insulation, high hardness and wear resistance, etc. However, due to its structure, ceramic materials lack the ability to slip and cause plastic deformation under stress like metals. They are prone to defects, cracks, and high stress concentrations, which determines the brittle nature of ceramic materials.
Therefore, improving the brittleness of ceramic materials is a long-term concern of ceramic scientists. In recent years, fiber reinforcement and zirconia phase change toughening have been proven in practice to be two effective ways to improve the brittleness of ceramics and strengthen ceramics
Structural ceramics are ceramics sintered with nano-yttrium stabilized zirconia powder. Due to its good performance in phase change toughening, it has become one of the main structural ceramics. In the research of nanocomposites, structural ceramics are strengthened and toughened with nano-yttrium-stabilized zirconia as a dispersed relative matrix, and remarkable results have been achieved.
