Advantages of Zirconia ceramics are as follows:

 

1. It has high hardness, toughness, and bending strength, and the density is between 5.95 - 6.05g/cm³. There are three kinds of ceramics produced by Touch-down, including aluminium oxide Al₂O₃, silicon carbide SiC, and zirconium oxide ZrO₂, among which zirconium oxide has the highest toughness, which is above 8MPa • m1/2.

​

2. It has a high-wearing feature and a low friction coefficient, whose abrasive resistance is 15 times that of aluminum oxide ceramics, while the friction coefficient is only 1/2 of aluminum oxide ceramics. After abrasive machining, its surface smoothness becomes even higher and can reach above ▽ 9. It is in mirror shape and extremely smooth, and the friction coefficient is lower.

 

3. It has good insulation and strong corrosion resistance, is static-free, heat-resistant, and has excellent heat-shielding performance, whose a coefficient of thermal expansion close to steel.

 

4. It is self-lubricating and can solve the problem of pollution caused by lubricating medium and the inconveniences added.​

 

 

Processing form of Zirconia Ceramics:
 

1. Processing by Opening the Mould: Dry-type forming machine, CIM injection forming. CIP equalizing processing and plate cutting processing.

 

2. Shape Processing Product: Plane grinding shall be adopted according to customer interface requirements, as well as inner/outer diameter grinding, NC program processing, and grinding and polishing.
