aluminaCeramics are widely usedceramicsBecause of its superior performance, it has been widely used in modern society, meeting the needs of daily use and special performance. Alumina ceramic is a kind of alumina (Al2O3) based ceramicceramic materialFor thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance。

1. External force：氧化铝陶瓷One of the main factors of wear is the strong external force. Generally, it is caused by the impact force and pressure in the operation process, and it is worn or broken due to the strong external force, which is not good for alumina ceramics. We should try to avoid the collision between it and the object in the operation process and minimize the damage.

2. Influence of external environment: the general environmental factors include the influence of medium, wind force and temperature in the environment. Sometimes, due to long-term wind erosion, alumina ceramics are worn; sometimes, due to the slight melting and damage of alumina ceramics caused by too high temperature; or the influence of impurities in the environment. No matter what factors in the environment lead to the wear of alumina ceramics, we need to timely repair and replace parts to ensure normal operation.

3. Too long use time: another reason for the wear of alumina ceramics is the wear after a long time of use, which is caused by the factor of time. Generally, we regard it as a normal factor and only need to replace it after it is excessively worn。
