Application of precision ceramics in automobile
Ceramics are essential products for a wide range of applications. Advanced ceramic materials (precision ceramics) are currently used in telecommunications, transportation, space exploration, defense, manufacturing, and even the automotive industry. Zirconia, silicon carbide, alumina and several other ceramic materials have been used in most of these applications.
In fact, precision ceramics have many unique applications in the automotive industry.
Application of precision ceramics in automobile
The automotive industry includes elements of electronic, mechanical, electrical, software, and safety engineering for the manufacture of motorcycles, automobiles, aircraft, ships, and any other components of automotive systems. Here are some interesting applications of ceramic materials in the automotive industry:
Automotive sensor
Ceramic materials are used to develop advanced monitoring systems. For example, a ceramic tire pressure monitoring system notifies the driver and occupants of a car of any sudden loss of tire pressure or that one of the tires does not have enough pressure.
An important requirement for automotive sensors is that they must be suitable for harsh environments, such as high temperature, low temperature, vibration, humidity, noise, or other environments where the vehicle is used for a long time. Ideally, it should also be small, lightweight, reusable, and have a wide output range. Similarly, ceramic sensors are widely used in heat resistance, corrosion resistance, wear resistance and other aspects.
Heat shield
Heat shields in cars are a common thermal management option. Due to its low price and decoration, it is the first choice. It has always been made of rigid steel, but has recently been made of flexible aluminum. Recently, advances in technology have led to the use of ceramic thermal barrier coatings on flexible aluminum. This allows for improved thermal insulation.
Silicon nitride ceramic positioning block
Ceramic materials are used to make brake components. The carbon fiber brake, originally composed of carbon fiber and resin, is pressed by a machine. It is then converted into a ceramic brake after other processes such as heating, carbonization and cooling.
Ceramic brake pads consist of a very hard carbon-silicon composite ceramic surface and a brake disc with a carbon fiber structure. These characteristics make ceramic brakes strong and highly susceptible to wear and corrosion. The technology is currently used in Formula 1 racing cars and other powerful cars.
Ceramic materials in automotive engines
Precision ceramics are widely used in aerospace and, more recently, in automotive engines. Engine components are the parts of the car that experience the highest stress, including several other factors such as temperature fluctuations, water splashes, and shocks. These are the perfect prerequisites for materials and system technologies to provide optimal performance. They provide excellent insulation and wear protection. They can usually withstand high temperatures and pressures and are usually stable.
Since ceramic materials are mostly lightweight and have very high heat, wear and corrosion resistance, they are well suited for such applications. They are a reliable source when conventional materials fail. Precision structural ceramics are used by today's design engineers due to their light weight and suitability for engine production.
Ceramic materials are used in engine manufacturing to minimize the chance of thermal damage. They are used to manufacture engine combustion chamber components such as cylinder liner, piston top jet, etc. With this treatment, the engine can reduce heat loss and reduce fuel consumption.
Ceramic valve disc
In the demand of harsh working conditions such as high wear and strong corrosion, the traditional metal valve plate is mainly reflected in the situation of easy leakage, large torque, and non-corrosion resistance of the sealing surface. Traditional metal valve plates need to be completely reformed in terms of material, design and processing technology. The application of ceramic materials to industrial valves is a bold and beneficial innovation.
Ceramic valve plate using high-performance structural ceramics, it has good self-cleaning, super wear-resistant, strong corrosion, strong self-lubrication, long service life, wide use environment, especially suitable for automotive fuel delivery.
Sum up
Precision ceramics have a very important contribution in the automotive industry. The most commonly used advanced ceramic materials for such applications include zirconia ceramics and alumina ceramics. They have particularly superior mechanical properties, which is why they can be machined into car parts.
