Ceramic structural objects There are many types, when it comes toThermal insulationZirconium oxide ceramic structural parts It is outstanding that such products are widely used in our lives. The mechanical properties of zirconia ceramic structural parts are indeed very good, but their use in special environments may significantly reduce the mechanical properties. What should I do?
Zirconium oxide structural ceramic parts It has special optical properties and high reflectivity for ultraviolet, medium wave and infrared rays. Therefore, after the coating dries, the nanoparticles densely fill the gaps between the coatings to form a complete The air insulation layer forms the coating. Zirconium oxide ceramic structure not only has good thermal insulation function, but also shows high strength and high destructive performance , wear resistance and other excellent mechanical properties, but after long-term use of 100 to 400, especially in humid environments, the so-called low-temperature aging phenomenon is prone to occur. Zirconia ceramic structureIn this case, according to the factors affecting the formation and aging of zirconia ceramics and the application of the material, different solutions should be adopted for the zirconia ceramic structure, which can be roughly divided into overall methods and surface methods. The overall method is to control the crystal particle size of the zirconium oxide ceramic structure and the content of the stabilizer yttrium oxide. Add high elastic modulus second phase dispersed particles into the product material.
Zirconium oxide ceramic structural parts Low-temperature deterioration starts from the surface and can be solved with the surface method, which essentially treats the surface of the product material to prevent the deterioration phenomenon from spreading to the interior. A large number of studies have shown that the grain size and stabilizer content in zirconia ceramic structural materials largely determine the stability of the tetragonal phase of the material and affect the low-temperature anti-aging performance of the material.
