Alumina piezo ceramics in the automotive applications

                                        Alumina piezo ceramics in the automotive applications

 First, the application of automotive ultrasonic transducer

The electronic ceramic sensor for automotive can be applied to the harsh environment , such as low temperature, high temperature, vibration, moisture acceleration, exhaust gas and so on, and should have good re-usability, small size, wide output range and so on. Piezo tube ceramics have resistance corrosion , heat resistance, optical function, wear and excellent electromagnetic, with the manufacturing technology developing in recent years. and can make full use of it ,sensors are made of piezo fully ,it can meet the requirements.

Second, technology applications of automotive spray

In recent years, aerospace technology is widely used ceramic film spraying technology ,it began to apply to the car. This technical advantages can withstand high temperature and high pressure, good thermal effect, mature technology, stable quality. In order to achieve low heat dissipation target, the engine combustion chamber components can be ceramic spray, such as cylinder liner spray zirconia, piston top spray zirconia. After this processing engine ,it can reduce the engine's own weight, reduce heat loss, reduce fuel consumption, reduce the engine size.

Third, the application of vehicle shock absorber by piezo ceramics

The use of high-sensitivity piezo cylinder ceramic components, the vehicle shock absorber with a recognition of the road and the use of high-sensitivity ceramic resonator, the use of shock absorber can have self-regulation function, the car can cause vibration to a minimum because of rough road.
