Zirconia ceramics play an important role in artificial joints, and their main functions are reflected in the following aspects:

Biocompatibility: Zirconia ceramics have good biocompatibility and will not cause allergies or rejection reactions when in contact with human tissues, so they can be safely used for artificial joint implantation.

Wear resistance: Zirconia ceramics have excellent hardness and wear resistance, which can withstand the friction and pressure generated by human joint movements and maintain long-term stable performance.

Wear resistance: In artificial joints, zirconia ceramics can reduce friction and wear with other materials (such as metals), reduce the degree of wear of artificial joints, and extend their service life.

Low friction coefficient: The low friction coefficient on the surface of zirconia ceramics enables smooth joint movement in artificial joints, reducing the heat and wear generated by friction.

High strength: Zirconia ceramics have high strength and toughness, which can withstand various forces and pressures during human joint movements, ensuring the stability and reliability of artificial joints
