Zirocnia Ceramics:
The commonly used fracture toughness measurement methods for Zirconia Ceramics are double-layer cantilever beam test, three-point bending or four-point bending test, indentation test, etc. Oian improves the stretching method, and evaluates the coating matrix by measuring the critical strain energy release rate. The three-point bending method for measuring the elastic modulus of the boundary theory is used in the method of measuring the elastic modulus of the coating. The three-point bending test is commonly used, and both the double-coated sample and the single-sided coated sample can be used.
The Si atom in the Si3N4 molecule is covalently bonded with the surrounding four N atoms to form a [Si-N4] tetrahedral structural unit. All tetrahedrons share the apex angle to form a three-dimensional space network, forming Si3N4, and having two phase structures, α phase. And β, zirconia ceramics are high temperature insoluble compounds, no melting point, strong resistance to high temperature creep, and binder-free reaction sintering Silicon Nitride load softening point above 1800 ° C, ion implantation technology is to expose the surface to ions Under the particle beam, a high-energy particle beam is injected into the surface of the substrate to form a solid solution on the surface, and the performance of the substrate does not change. The corrosion of si3N4 in 1000e molten Na2CO3 in the presence of oxygen can be divided into three stages. The rapid weight loss is mainly due to the decomposition of the first 5m Na2CO3 and the formation of Na2 SiO3.
