Alumina ceramic is a kind of widely used ceramic. Because of its superior performance, it has been used more and more widely in modern society, meeting the needs of daily use and special performance. Alumina ceramic is a kind of ceramic material with alumina (Al2O3) as the main body, which is used in thick film integrated circuit. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance.1. External force: one of the main factors that alumina ceramics are worn 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 the external environment: the general environmental factors include the influence of the medium in the environment, the influence of the wind force, the influence of the temperature, etc., sometimes the abrasion of the alumina ceramics will be caused by the long-term wind erosion; sometimes the slight melting and damage of the alumina ceramics will be caused by the high temperature; or the influence of the 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. Long service life: 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.
