Silicon Carbide Ceramics In Automobile And Other Special Application And Progress
Rapid degeneration of silicon nitride a good temperature resistance
, high hardness, the hardness is second only to diamond, boron nitride and other materials, with silicon nitride Ceramics Manufacture of engines, due to operating temperature up to 1370 degrees Celsius, the engine can increase the efficiency of 30%. At the same time due to temperature increase, can fuel combustion, exhaust emissions components decreased significantly, not only reduce energy consumption and reduce environmental pollution.Other special ceramic materials, types are also very many, they have their own characteristics, can be made into a variety of functional elements. Lithium oxide ceramic materials for high temperature, high-frequency steatite ceramics Insulation , Thorium oxide ceramic dielectric materials, optical materials, barium titanate ceramics, boride, nitride, silicide, metal ceramics for ultra-high temperature materials. Ferrite ceramic magnets, memory magnet, magnetic heads and other materials, rare earth cobalt ceramic materials for the memory, the semiconductor ceramic components for the Yamin, solar cells and other materials. Many species can be used Car Parts or testing device. Currently, the application of special ceramic materials, Automobile important progress has been made. They are mainly the following aspects.
1, the application of ceramic automobile engine New ceramic silicon carbide nitride, etc.
inorganic sintered. Compared with the previous use of alumina, the intensity of its more than three times, the ability of a high temperature above 1000 degrees Celsius, new materials, new uses for advanced vehicle development. For example: To reduce the diesel fuel cost more than 30%, can be indispensable for the new ceramic material. Is gasoline, burning about 78% of heat energy lost as heat transfer, engine thermal efficiency was 33%, compared with the gasoline engine has been very favorable, but there are still more than 60% lost as heat energy. Therefore, in order to reduce this loss, with the thermal performance of good ceramic material surrounding the combustion chamber to conduct heat, and then use the power turbocharger exhaust turbine to recover energy, there are tests proved that the thermal efficiency can be increased to 48% . the same time, new ceramic use, quick start diesel engine will become possible moment. Using new ceramic turbochargers, than today's superalloys with superior thermal stability, while the proportion was only about one third of the metal turbine. Therefore, the new ceramic turbine can compensate for the dynamic response of low metal turbine shortcomings. Other studies are being undertaken are: using the new ceramic piston pin piston rings and other moving parts. As the weight, engine efficiency is expected to be improved.
2, Special Sensitive Ceramic automotive sensor applications
Requirements on automotive sensors can be applied to car-specific long-term adverse environment (heat, cold, vibration, acceleration, humidity,. Sound, exhaust), and should have a small light weight, good re-use, the output characteristics of a wide range of . Ceramic heat-resistant, corrosion resistance, wear resistance and excellent potential electromagnetic, optical function, as manufacturing technology advances in recent years, the full use of sensitive sensors made of ceramic materials can satisfy those requirements.
Third, the application of ceramic brakes
Demands on automotive sensors can be applied to car-specific long-term adverse environment (heat, cold, vibration, acceleration, humidity,. Sound, exhaust), and should have a small light weight, good re-use, the output characteristics of a wide range of . Ceramic heat-resistant, corrosion resistance, wear resistance and excellent potential electromagnetic, optical function, as manufacturing technology advances in recent years, the full use of sensitive sensor made of ceramic materials can satisfy those requirements.
4, the application of ceramic Absorber
Limousine damping device utilization is sensitive ceramic piezoelectric effect, converse piezoelectric effect of electrostrictive effect of the successful development of smart damper. As a result of the high sensitivity of ceramic components, this shock absorber has identified the road and do self-adjustment function can be caused by car because of rough road vibration to a minimum.
