1、 Application of Special Sensitive Ceramic Automotive Sensors

It is required that the electronic ceramic sensors for automobiles can be applied to the specific harsh environment of automobiles for a long time (high temperature, low temperature, vibration, acceleration, humidity, sound, exhaust gas), and should have the characteristics of small size, light weight, good reusability, wide output range, etc. Ceramic is heat-resistant, corrosion-resistant, wear-resistant and has potential excellent electromagnetic and optical functions. In recent years, with the progress of manufacturing technology, it has been fully utilized. Sensors made of sensitive ceramic materials can fully meet the above requirements.

2、 Application of Ceramic Material in Automobile Spraying Technology

In recent years, aerospace technology has been widely applied to ceramic film spraying technology, which has been applied to automobiles. This technology has the advantages of good thermal effect, high temperature and pressure resistance, mature process and stable quality. In order to achieve the goal of low heat dissipation, ceramic coating can be applied to the engine combustion chamber components, such as zirconia sprayed on the piston top and zirconia sprayed on the cylinder liner. After this treatment, the engine can reduce heat loss, reduce the engine’s own mass, reduce the engine size, and reduce fuel consumption.

3、 Application of alumina ceramic shock absorber in automobile

The smart shock absorber for premium cars has been successfully developed by comprehensively utilizing the positive piezoelectric effect of sensitive ceramics and the electrostriction effect of the reverse piezoelectric effect of alumina ceramics. Due to the use of highly sensitive ceramic components, this kind of shock absorber has the function of road surface identification and self adjustment, which can minimize the vibration caused by the rough road surface of the car.
