Surface Finish Processing of Zirconia Ceramics

Zirconia ceramics have high melting and boiling points, high hardness, insulators at room temperature, and electrical conductivity at high temperatures.

Zirconia ceramics have high melting and boiling points, high hardness, insulators at room temperature, and electrical conductivity at high temperatures.

Zirconia ceramics are widely used, and zirconia ceramics must be processed to get a smooth surface. This article will introduce the surface finish processing technology of zirconia ceramics.

Surface finishing processing refers to a processing technology that greatly improves the surface finish of the processed ceramic parts while achieving accuracy stability, and can even improve the processing accuracy level. It is the last process in the processing of most ceramic parts.

The main functions of ceramic parts finish processing:

1. Reduce the surface roughness of parts, remove surface defects such as scratches and micro-cracks, and improve and improve the surface quality of parts.

2. Improve the physical and mechanical properties of the surface of the parts, improve the surface stress distribution of the parts, and improve the performance and life of the parts.

3. Improve the gloss and brightness of the surface of the parts, and improve the cleanliness of the surface of the parts.

4. Remove burrs, rounding, chamfering, etc., to ensure a smooth transition between surfaces, and improve the assembly efficiency and fit of parts.

Surface finish processing technology can be divided into two categories according to the historical evolution and the processing mechanism used:

One type is a simple mechanical finishing method based on the cutting process principle, which is collectively referred to as traditional finishing technology, includes mirror grinding, honing, superfinishing, grinding, and polishing.

The other is a finishing method that combines chemical or electrochemical dissolution processing, high-energy processing, and multiple processing principles. It is called non-traditional finishing technology, which mainly includes chemical light, electrochemical polishing, and pulses electrochemical finishing. , Electrochemical mechanical finishing and ultrasonic processing, etc.

The above is the introduction of the surface finish processing technology of zirconia ceramics introduced by Mingrui Ceramics. I hope this article can help you.
