Application of Aluminum Nitride in Aerospace
Aluminum nitride plays an important role in aerospace and aviation due to its high thermal conductivity, good electrical insulation properties, high strength and high wear resistance.
1. Electronic equipment: it can be used as heat sink, encapsulation material and substrate of electronic components, etc., which helps to improve the performance and reliability of electronic equipment.
2. Structural parts of aerospace vehicles: the high strength and wear resistance of aluminum nitride ceramics make it an ideal material for manufacturing structural parts of aerospace vehicles, including aircraft engine parts, landing gears, etc., which helps to improve the safety and performance of aerospace vehicles.
3. Heat-resistant punch and heat exchange materials: Aluminum nitride ceramics can be used as ideal heat-resistant punch and heat exchange materials due to its excellent thermal conductivity and low coefficient of thermal expansion, for example, heat exchanger materials for marine gas turbines and heat-resistant parts for internal combustion engines, which effectively improves the heat transfer capacity of heat exchangers.
4. Wear-resistant, heat dissipation and insulating parts in high temperature environment: Aluminum nitride ceramics are used in aerospace field for wear-resistant, heat dissipation and insulating parts in high temperature environment, such as nozzles and heat sinks of jet engines, etc., which ensures the reliable operation of aviation and spacecraft in extreme conditions.
In summary, the application of aluminum nitride in aerospace field not only improves the performance and reliability of equipment, but also enhances the safety and durability of aviation spacecraft, which is one of the indispensable materials in aerospace field.
