First, the application of ceramics in automotive engines
The new ceramics are sintered by inorganic non-metals such as silicon carbide and silicon nitride. Compared with the solidified alumina ceramics used in the past, its strength is more than three times, and it can withstand high temperatures of more than 1000 degrees Celsius. New materials have promoted the development of new applications in automobiles. For example: to reduce the fuel consumption of diesel engines by more than 30%, it can be said that new ceramics are indispensable materials. Now in gasoline engines, about 78% of the combustion energy is lost in thermal energy and heat transfer. The diesel engine has a thermal efficiency of 33%, which is very superior to gasoline, but still more than 60% of the thermal energy is lost. Therefore, in order to reduce this part of the loss, the combustion chamber is surrounded by a ceramic material with good thermal insulation properties for heat insulation, and then exhaust gas turbochargers and power turbines are used to recover exhaust energy. Tests have proved that this can improve thermal efficiency to 48%. At the same time, due to the new ceramic turbocharger, it has better heat resistance than today's super heat-resistant alloys, while the specific gravity is only about one third of that of metal turbines. Therefore, new ceramic turbines can compensate for the shortcomings of low dynamic response of metal turbines. Other ongoing researches include the use of new ceramic piston pins and moving parts such as piston rings. Due to the reduced weight, engine efficiency is expected to improve.
Application of special sensitive ceramics in automotive sensors
The requirements for automotive sensors are long-term adaptation to the harsh environment of the car (high temperature, low temperature, vibration, acceleration, humidity, noise, exhaust gas), and should be small and lightweight, good reusability, and wide output range. Ceramics are heat-resistant, corrosion-resistant, wear-resistant, and their potential excellent electromagnetic and optical skills. In recent years, with the advancement of manufacturing technology, ceramics have been fully utilized. Sensors made of sensitive ceramic materials can fully meet the above requirements.
Application of ceramics in automobile brakes
Ceramic brakes are manufactured on the basis of carbon fiber brakes. A carbon fiber brake disc is initially composed of carbon fiber and resin. It is pressed by a machine and then made into a ceramic brake through several processes such as heating, talking, heating, and cooling. The hardness of the surface of the carbon silicon compound of the ceramic brake is close to that of a diamond. The carbon fiber structure in the disc makes it strong and impact-resistant and corrosion-resistant, making the disc extremely wear-resistant. At present, such technologies are not only used in F1 cars, but also in civilian sports cars, such as Mercedes-Benz CL5MG.
Fourth, the application of ceramics in automobile shock absorbers
The shock absorber of a high-level car is a smart shock absorber successfully developed by comprehensively utilizing the sensitive ceramic positive piezoelectric effect, reverse piezoelectric effect, and electrostrictive effect. Due to the use of high-sensitivity ceramic elements, this shock absorber has the function of identifying the road surface and making self-adjusting. Can reduce the vibration caused by the rough halogen surface of the car to a minimum.
V. Application of ceramic materials in automotive spraying technology
In recent years, ceramic thin film spraying technology widely used in aerospace technology has begun to be applied to automobiles. The advantages of this technology are good thermal insulation, high temperature and pressure resistance, mature technology, and stable quality. To achieve the goal of low heat dissipation. Ceramic spraying of engine combustion chamber components is possible. Such as zirconia sprayed from the top of the piston. Liner sprayed zirconia. After this treatment, the engine can reduce heat loss, reduce engine mass, reduce engine size, and reduce fuel consumption.
Application of intelligent ceramic materials in automobiles
Intelligent ceramic materials classified as special ceramic products, including materials used in automobile manufacturing that are sensitive to the environment and capable of responding to environmental changes, have now become the focus of research in the field of materials science and engineering.
