Ceramic processing parts are now applied in many fields. Zirconia ceramics have high melting point and boiling point, high hardness, insulator at room temperature, and conductivity at high temperature. In order to make zirconia ceramics have beautiful appearance, surface treatment of zirconia ceramics is needed. What are the common surface treatment processes of zirconia ceramics? Here's an introduction for you.

1. PVDPVD refers to the method of forming metal or compound coatings with special functions on the surface of workpiece by physical or chemical reaction process. At present, evaporation and sputtering are the main plating methods, such as logo or color film on the ceramic cover .

2. AF ProcessingAF treatment, also known as anti-fingerprint coating treatment, uses evaporation method to coat the ceramic surface with a layer of coating, which makes the ceramic surface not easy to produce fingerprints, good wear resistance. In addition to fingerprint protection, this process can also prevent scratches, add wear resistance and touch, and will not change the original structure. However, the life of this coating is often not long, and it will lose its efficacy after a period of time. 

3. Wire drawingWire drawing is a process of rubbing marks on the surface of products by means of mechanical processing. There are several kinds of wire drawing, such as straight thread, screw thread, ripple, and solar ripple.

4.glaze burningGlaze is a thin layer of colorless or colored glass covering the surface of ceramic products. It is made of mineral materials (feldspar, quartz, talc, kaolin, etc.) by grinding, applying to the surface of the body and calcining at high temperature. It can add mechanical strength,thermal stability and dielectric strength of products. It also has the characteristics of beautifying parts, being easy to clean and not being corroded by dust. Firing glaze belongs to theapplication of traditional ceramic technology combined with industrial ceramics. 

5. Laser SculptureThe principle of laser engraving is to use high-intensity laser beams emitted by lasers to make evaporation of surface materials expose deep-seated materials, or to cause chemical changes of surface materials to form the desired pattern through light energy.
