Solution treatment and gas source of zirconia ceramics

In the production process of zirconia ceramics, due to the influence of high temperature during rolling, stretching and welding, the microstructure and mechanical properties of the materials will change, which will seriously affect the quality of pipes. These changes mainly include: cold work hardening, that is, one or more rows of atoms in the crystal are regularly staggered, and the lattice is distorted, forming a stress concentration area, which is also called dislocation.

Because of the welding stress caused by high temperature and uneven cooling, ferrite and carbide are produced in the original single austenite structure, in order to improve production efficiency, ensure the bright surface of the coil, eliminate residual stress, obtain a single austenite structure and produce high-quality coil, the online bright solid solution treatment method must be implemented.

Gas source of zirconia ceramics

1, zirconia ceramic feeding system and air in the cavity.

2. Water vapor generated by the evaporation of water contained in zirconia ceramics at high temperature.

3. Gases generated by the decomposition of zirconia ceramic products.

4. Some additives in zirconia ceramics volatilize or chemically reflect the generated gas.

5. Air and moisture mixed in zirconia ceramic feed.
