Silicon nitride ceramics have various important applications in the automotive industry, mainly reflected in the following aspects:

Engine components: Silicon nitride ceramics have excellent wear resistance and high temperature resistance, so they are often used to manufacture engine components, such as piston rings and pins coated with silicon nitride ceramics. These components can improve the performance and lifespan of the engine, reduce wear and energy consumption.

Lubrication system: Silicon nitride ceramic coating is often used to manufacture friction components in engine lubrication systems, such as piston rings, cylinder liners, etc. These ceramic coatings have excellent wear resistance and low friction coefficient, which can reduce the friction loss of components and improve the fuel efficiency of automotive engines.

Exhaust system: Silicon nitride ceramics are also used to manufacture components in exhaust systems, such as turbocharger blades, exhaust manifolds, etc. These ceramic components have good high temperature resistance and corrosion resistance, can withstand high temperature and high pressure exhaust airflow, and improve engine performance and efficiency.

Brake system: Silicon nitride ceramics are often used as brake disc materials in brake systems. Compared to traditional iron brake discs, silicon nitride ceramic brake discs have better wear resistance, high temperature resistance, and thermal expansion resistance, providing more stable braking performance and shorter braking distance.

Transmission system: Silicon nitride ceramics are also used in transmission systems, such as in manufacturing components such as transmission gears and clutch friction plates. These ceramic components have excellent wear resistance and heat resistance, which can improve the efficiency and reliability of the transmission system.
