Auto parts are generally made of different materials, including plastic, steel or ceramics. Zirconium oxide ceramic The advantages of the material are fully demonstrated in automobiles, because many parts of automobiles are made of this material. It is involved in important devices such as engines, sensors, brakes, and shock absorbers. Let’s watch the new energy vehicles together with the editor of Mingrui Ceramics What are theceramic parts?
What are the ceramic parts of new energy vehicles - Introduction
Learn more about the qualities of special ceramics that attract users. This kind of zirconia ceramic is sintered with inorganic non-metals such as zirconia and yttria. Therefore, compared with the alumina ceramics used in the past, its strength and high temperature resistance are significantly improved, further improving its Application effects in the automotive field.
Automobile engines made of traditional materials have serious heat loss problems. In order to reduce this loss, it is necessary to use zirconia ceramic materials with good thermal insulation properties to surround the combustion chamber for heat insulation, and then use exhaust gas turbochargers and power turbines to recycle the heat. Exhaust energy, thereby effectively improving the thermal efficiency of the automobile engine.
The basic requirements for automotive sensors are that they must be able to be used in the harsh environments unique to automobiles for a long time, and they must also be small and lightweight, have good reusability, and have a wide output range. Sensors made of zirconia ceramics just meet the above requirements, because ceramics are heat-resistant, corrosion-resistant, wear-resistant and have potentially excellent electromagnetic and optical properties.
There are also Zirconium oxide ceramic brakes which are also made on the basis of carbon fiber brakes. They have undergone many processes such as pressing, heating, carbonization, heating and cooling. Since the hardness of the carbon silicon compound surface of this type of brake is close to diamond, its impact resistance and corrosion resistance are very outstanding.
In recent years, zirconia ceramic materials have also been widely used in automobile spraying technology. Engines treated in this way can reduce heat dissipation loss, reduce the weight of the engine itself, reduce engine size, and reduce fuel consumption. In addition, smart ceramic materials, as a type of zirconia ceramics, have also become the focus of attention.Point, the smart material system or structure that combines functional materials, drive systems and feedback systems on cars is made of this material.
What are the ceramic parts of new energy vehicles? How to process ceramic parts?
For processing ceramic parts, the best tool is a toothless diamond grinding wheel, which contacts the workpiece at the highest speed and the slowest contact speed. Coolant must be supplied before contacting the workpiece. Ceramic materials have extremely high hardness andIt has good wear resistance and corrosion resistance and other characteristics. It is a difficult-to-machine material and cannot be effectively machined using usual metal cutting methods.
The current research on ceramic processing technology can be summarized into two aspects:
A Conduct in-depth research on existing ceramic processing technology, develop special ceramic processing machine tools, optimize process parameters, improve processing quality and processing efficiency, and reduce production costs to expand its application scope.
B Develop and promote new technologies for ceramic processing. The development trend is to combine two or several processing methods to form a new processing method. This can not only greatly improve processing efficiency, and can improve the processing quality of engineering ceramic parts.
What are the ceramic parts of new energy vehicles - types
(1) NormalHybrid vehicles refer to models that use traditional fuel and are equipped with an electric motor/engine to improve low-speed power output and fuel consumption.
(2) Plug-in hybrid electric vehicles can obtain electrical energy from non-vehicle devices under normal use to meet the vehicle's requirementsPure electric driving range .
(3) Pure electric vehicles are mainly used Electrically powered cars. There is a vehicle-mounted rechargeable battery or other energy storage device that provides electrical energy.
(4) Gas vehicles refer to vehicles that use compressed natural gas, liquefied petroleum gas and liquefied natural gas as fuel.
(5) Hydrogen-powered vehicles are truly zero-emission vehicles that emit pure water. It has the advantages of no pollution, zero emissions and abundant reserves.
(6) Bioethanol vehicles refer to using ethanol instead of petroleum fuel, also called alcohol vehicles. The use of ethanol can increase the octane number of the fuel, increase the oxygen content, and make the combustion in the automobile steel more complete, which can reduce the harmful emissions of the exhaust gas. Of course, the significance of new energy vehicles for environmental protection is that it changes the dependence of automobiles on fossil fuels, has the opportunity to alleviate the oil crisis, and will also change the energy structure of society. That is to say, when the proportion of thermal power decreases and wind power, hydropower, nuclear power and solar power become more popular and promoted, new energy vehicles will have the opportunity to becomeTo be truly environmentally friendly.
If the parts are made of ceramic material, there are many benefits. New energy vehicles have always been the focus of discussion in the global energy community. The number of electric vehicles will grow rapidly in the next period, which will inevitably have a great impact on the power grid. In 2030, the number of electric vehicles in the world will reach 125 million. China, the United States, Europe, etc. are undoubtedly the countries or regions with the highest concentration of electric vehicle sales in the world. I hope that the relevant information shared by the editor of Mingrui Ceramics about What are the ceramic parts of new energy vehicles can help everyone Better awareness.
