1: Structure: Generally speaking, the high-temperature strength of ionic bond wear resistant ceramic tiles is lower than that of covalent bond ceramics. At high temperatures, the impurity glass phase of the green body will undergo greater plastic deformation, resulting in a sharp decrease in strength. For poly crystalline ceramics, to a large extent It depends on the high temperature properties of the grain boundaries.
2. Stomatal: An increase in pores will inevitably lead to a decrease in high-temperature strength. At high temperatures, due to passivation of crack tips and other reasons, ceramic materials are less susceptible to cracks and micro-defects, which is mainly reflected in the impact on fracture toughness.
3. Grain: If the diameter of the grain is small, the particles will move easily, the deformation speed will be high, and the high-temperature strength will drop sharply. The influence of the grain shape is not yet conclusive. Generally speaking, sintered bodies composed of grains with obvious anisotropy have high strength. .
4. Temperature: Different materials have different strength changes with temperature. Its fracture mechanism changes from brittle fracture at low temperature to ductile fracture at high temperature, so it has a certain brittle-ductile transition temperature.
5. Conditions of use: The atmosphere that oxidizes non-oxides, and the surface of oxides is rough or cracked will reduce the strength.
The factors that affect the wear-resistant ceramic tiles are not only the temperature range, the erosion intensity of the particles, the force conditions, but also the characteristics of the corrosive medium, the size of the impact angle of the hard particles and other factors. In short, the wear-resistant ceramic tiles Performance is affected by these factors, and only when these factors are least affected can wear-resistant ceramic sheets exert their maximum performance characteristics.
Wear resistant ceramics tiles are designed in different shapes and sizes according to different usage environments. The thicker the thickness, the longer the ceramic will last. Chemshun Ceramics will provide you with wear-resistant ceramic consultation, design and other services.
