Zirocnia Ceramics:

Surface strengthening is the toughening of ceramic materials to produce fractures that tend to occur when the surface is subjected to tensile stresses beyond the fracture stress. The surface t-ZrO2 ceramic particles are less constrained, and the particles are easily converted from t-ZrO2 to m-ZrO2, but the t-ZrO2 inside the matrix is still metastable under pressure in different directions. The m-ZrO2 on the surface of the material is much more than the m-ZrO2 inside the material matrix, and the volume effect caused by the phase change accumulates on the surface of the material to form residual compressive stress, which can offset the applied partial tensile stress and thus strengthen the surface toughening. The existing phase transformation toughening mechanism has extremely strong temperature sensitivity, and the toughening effect at high temperature is greatly limited, especially the stress-induced phase transformation toughening is basically failure in the high temperature region. Therefore, how to expand the effective temperature range of the existing mechanism and seek a new phase change toughening mechanism will be the key to solving the problem of high temperature toughening.
3.2 synergistic toughening
In the future, zirconia toughened ceramic materials will be the result of a variety of toughening mechanisms, so the interaction between the phase-change toughening mechanism and other mechanisms, and the conditions for synergistic toughening effects between various mechanisms will also be One of the main research directions of ZrO2 ceramic material toughening technology.
3.3 nanoparticle toughening
Most of the multiphase ceramics studied in the past are micron multiphase ceramics, that is, the grain size of each phase in the material is micron, and the second phase particles are mainly distributed on the grain boundaries. From the existing reports, when the second phase toughened particles are reduced from micron to submicron or nanometer, the properties of the material tend to change significantly. Nanocomposite ceramics came into being. Therefore, the future nano-scale second phase toughening particles will be one of the focuses of research and development of ZrO2 ceramic material toughening technology.
