Description
Technical Field
The invention relates to the technical field of ceramic materials, in particular to a preparation method of anti-aging yellow zirconium ceramic.
Background
Zirconia ceramics have high strength, high toughness, corrosion resistance, wear resistance and good biocompatibility, and are widely applied to the fields of materials, chemical industry, metallurgy, medical treatment and the like. Zirconia has three crystal forms of monoclinic phase, tetragonal phase and cubic phase, wherein the tetragonal phase changes into martensitic phase, and the process can generate 8% of shear strain and 3% -5% of volume increment, so that the application of the zirconia is limited. In order to avoid the volume effect caused by the phase change, a stabilization treatment is generally performed by doping a stabilizer. Currently common oxide stabilizers are alkaline earth metal oxides (e.g., caO, mgO, etc.) and rare earth metal oxides (e.g., Y2O3, la2O3, etc.). The addition of the stabilizer can cause low-temperature aging problem to the zirconia ceramics, and the zirconia ceramics can fail due to surface cracks in a humid environment at 100-400 ℃. This is because the stabilizer forms a solid solution with ZrO2 and generates a proportion of valence-compensated oxygen vacancies due to the different cation valence states. Taking Y-TZP as an example, in a humid environment, moisture is adsorbed on the surface of the Y-TZP and ionized to form OH < - >, permeates into oxygen vacancies of the surface layer of the Y-TZP and compensates electricity price, so that Y < 3+ > is deviated to a place with high concentration of the oxygen vacancies, the surface of the OH < - > -permeated layer cannot stabilize t-ZrO2 because of the reduced concentration of Y < 3+ >, so that t- > m phase transformation occurs, the volume is increased to generate microcracks, and zirconia ceramics are destroyed to fail after the microcracks develop into macroscopic cracks. The problem of low temperature aging of zirconia ceramics has been of great concern because of its direct impact on its useful life.
The main ways of improving the ageing resistance of the zirconia ceramics are adding a stabilizer, refining grains, increasing compactness and the like, and the latter two ways are influenced by the sintering process, the type of the stabilizer and the content of the stabilizer, so that the ageing resistance of the zirconia ceramics is improved mainly by changing the type of the stabilizer and the content of the stabilizer under the same sintering process. Among them, zirconia ceramics added with various stabilizers are more excellent in aging resistance. At present, the common anti-aging zirconia ceramics are prepared by adding two to three stabilizers, and the ageing resistance is optimized, but the service life is still insufficient and still needs to be improved.
