The machining performance of zirconia ceramics


2021-05-19


Zirconia ceramic accessory materials usually need to go through the blank cutting, grinding, grinding and polishing processes to make the required parts. This process requires machining. The machining performance of zirconia ceramics includes cutting, grinding, grinding and polishing.

1 Zirconia ceramic cutting, grinding, grinding and polishing
There are three commonly used methods for zirconia ceramic cutting: fixed abrasive cutting, free abrasive cutting and single-edge cutting. The application development of high-performance industrial ceramics is based on the three-phase composite ceramic material ZTA as the raw material, the ceramic drawing mold and ceramic tower wheel and its industrial application products are developed and produced.

2 Plastic deformation of zirconia ceramics
Zirconia ceramics has no plastic deformation at room temperature, and its compressive strength is large, but its tensile, flexural and impact resistance are small, and it is easy to brittle fracture. According to the ratio of materials, the theoretical strength of zirconia ceramics is very high, but its actual strength is only about 1% of the theoretical strength.

3 Strengthening of zirconia ceramics
At present, the more mature strengthening technologies include composite strengthening, porcelain crystallization, porcelain densification, and pre-stress strengthening. The application and development of high-performance structural industrial ceramics is based on the three-phase composite ceramic material ZTA as the raw material, and the ceramic drawing mold and ceramic tower wheel and industrial application products are developed and produced.
