Special ceramics are different from traditional ceramics in chemical composition, internal structure, performance and use efficiency, and it has a variety of excellent and unique properties. Researchers engaged in automotive materials, after years of development, development, testing and industrial applications have proved that many parts and components of automobiles have been converted to ceramic materials, and their mechanical properties are far better than those made of metal materials or other materials. It is precisely because of the excellent performance of special ceramics that it has positive significance for reducing the weight of the vehicle itself, improving the thermal efficiency of the engine, reducing fuel consumption, reducing exhaust pollution, improving the life of wearing parts, and improving the intelligent function of the car.

Engine components

1. Cylinder liner and piston ring

Ceramic materials can overcome the wear of metal materials, thermal expansion coefficient difference and other problems. It has excellent wear resistance, high temperature strength and low thermal expansion coefficient. Ceramic liner can reduce the heat loss of automotive engines and increase fuel efficiency.

2. Valve

The main body of alumina ceramic valve chip is alumina ceramic and metal substrate, its strength and wear resistance are much better than ordinary cast iron and steel valve.

Brake system

Brake force is large, the use of high frequency, ceramic material hardness, thermal stability and corrosion resistance are in line with the use of automotive brake system requirements. At present, the main components of the brake system are as follows:

1. Brake pads

Brake pads made of ceramic composite materials not only have a longer service life, but also do not produce a lot of dust and noise when braking.

2. Brake disc

The brake disc made of ceramic is lighter than the ordinary metal brake disc, the coefficient of thermal expansion is lower, the service life is longer, and the braking performance is better.

The horn

The high-frequency characteristics of ceramic materials are very favorable for the manufacture of horns, and the high-frequency horns made of ceramic materials are not easy to be deformed, which can ensure the stability and high quality of the sound.

Turbocharger

Turbocharger is an important device to improve the power performance of automobiles. The application of ceramic materials can effectively reduce the heat loss and inertia loss, and improve the efficiency of turbocharger.

Sensor

The sensor is an important part of the automotive electronic control system, and ceramic materials are widely used in vehicle sensors because of their excellent physical properties, such as oxygen sensors, pressure sensors, temperature sensors, etc.

Ceramic materials are widely used in the automotive industry. Ceramic materials can not only improve the performance and life of the car, but also improve the appearance and safety of the car.
