Introduction silicon nitride part
Except for hydrofluoric acid, silicon nitride does not react with other inorganic acids, has strong corrosion resistance, and is resistant to oxidation at high temperatures.
Moreover, it can also resist cold and heat shocks, heat to more than 1000 °C in the air, and cool sharply and then sharply without chipping.
Application of silicon nitride bush
People often use it to manufacture mechanical components such as bearings, gas turbine blades, mechanical seal rings, and permanent molds.
If silicon nitride ceramics that are resistant to high temperature and are not easy to transfer heat are used to manufacture the heating surface of engine parts, it can not only improve the quality of the diesel engine, save fuel, but also improve thermal efficiency.
Advantages
1.Silicon nitride ceramic materials have high thermal stability and strong oxidation resistance.
2.Silicon nitride has good chemical stability and is not oxidized below 1200°C.
3.Silicon nitride ceramics have excellent mechanical properties and machinability.
