There are several types of technical ceramics, such as zirconia ceramics and alumina ceramics. Their mechanical properties are particularly superior, so they can be processed into auto parts. This article will give you a detailed introduction to the application of technical ceramics in the automotive industry.
1. Application of sensitive ceramics in automotive sensors
The requirement for automotive sensors is that they can be used in the harsh environment (high temperature, low temperature, vibration, acceleration, humidity, noise, exhaust gas) unique to the car for a long time, and should be small and lightweight, reusable, and have a wide output range.
Ceramic heat resistance, corrosion resistance, wear resistance, and its potential excellent electromagnetic and optical functions have been fully utilized in recent years with the advancement of manufacturing technology. Sensors made of sensitive ceramic materials can fully meet the above requirements.
2. The application of ceramics in automobile brakes
Ceramic brakes are manufactured on the basis of carbon fiber brakes. A carbon fiber brake disc is originally composed of carbon fiber and resin. It is pressed into shape by a machine, and then it is made into a ceramic brake through several processes such as heating, carbonization, heating, and cooling.
The hardness of the carbon-silicon compound surface of the ceramic brake is close to the diamond, and the carbon fiber structure in the disc makes it strong and resistant to impact and corrosion, making the disc extremely wear-resistant. At present, this kind of technology is not only applied in F1 racing cars, but also involved in super civilian sports cars, such as Mercedes-Benz CL55 AMG.
3. Application of technical ceramics in automotive shock absorbers
The damping device of a luxury car is an intelligent damping device that is successfully developed by using the positive piezoelectric effect, inverse piezoelectric effect, and electrostrictive effect of sensitive ceramics.
Due to the use of high-sensitivity ceramic components, this type of shock absorber has the function of identifying the road surface and self-adjusting, which can minimize the vibration caused by the rough road surface of the car.
4. Application of ceramic materials in automobile engines
In recent years, technical ceramics, which are widely used in aerospace, have begun to be used in automobile engines. The advantages of this kind of ceramic are good heat insulation effect, ability to withstand high temperature and high pressure, mature technology, and stable quality.
In order to achieve the goal of reducing engine thermal damage, ceramic materials are used to manufacture engine combustion chamber components, such as piston top injection, cylinder liners, and so on. The engine after this treatment can reduce the heat loss, reduce the quality of the engine itself, reduce the size of the engine, and reduce fuel consumption.
