How to improve the wear resistance of alumina ceramics linings?

As manufacturer and exporter of wear resistant alumina ceramic linings,  Chemshun Ceramics keep studying and improving the ceramics property , surely we went far away in improving wear resistance of alumina ceramics , The following methods can be taken:

 

1. Influence of raw material powder: the use of high-purity, fine-grained alumina powder is an important prerequisite for the preparation of alumina wear-resistant ceramics with excellent performance. The quality and particle size of the raw material powder has a significant impact on the wear resistance of ceramics. Only if the raw material is fine enough, the final fired product is likely to form a microcrystalline structure, thus improving wear resistance.

2. Doping of rare earth oxides: Studies have shown that the doping of appropriate amounts of rare earth oxides (such as La2O3, Sm2O3, etc.) can improve the wear resistance of alumina ceramics. Rare earth oxides can generate intergranular compounds with alumina to strengthen the strength of grain boundary bonding, thus improving the wear resistance of ceramics.

 

3. Surface strengthening treatment: By strengthening the surface of alumina ceramics, such as coating, infiltration, ion implantation, etc., its wear resistance can be further improved. These surface strengthening treatments can form a layer of higher hardness and better wear resistance on the surface of the ceramics, thus extending the service life of the ceramics.

 

4. Control of the preparation process: the preparation process also has a great influence on the wear resistance of alumina ceramics. Through the optimization of molding, sintering and other process parameters, you can get high density, grain uniformity, compact structure of the ceramic material, thus improving its wear resistance.

 

5. Composite enhancement: alumina ceramics and other high-performance materials (such as silicon carbide, silicon nitride, etc.) for composite, can further improve its wear resistance. This composite enhancement method can enhance its wear resistance by improving the hardness, strength and toughness of the material.

 

In summary, the wear resistance of alumina ceramic lining tile can be further enhanced by optimizing raw materials, doping rare earth oxides, surface strengthening treatment, controlling the preparation process, and composite enhancement. These methods can be selected and combined according to specific application scenarios and needs.
