Is aluminum forging suitable for use in high-temperature environments? Please use a practical production case to illustrate and write an article in Chinese and translate it into English.
Aluminum forgings are lightweight, high-strength metal products that have good properties such as corrosion resistance, conductivity, thermal conductivity, and mechanical processing. However, when used in high-temperature environments, aluminum forgings need to consider issues such as material thermal stability, oxidation resistance, and stress relaxation.
Generally, aluminum forgings can be used normally in environments below 150℃, while special material treatment and design are required to ensure their reliability and service life in high-temperature environments. For example, high-temperature alloy plating, surface oxidation treatment, and other methods can be used to improve the material’s high-temperature resistance, and the material’s linear expansion coefficient and thermal expansion coefficient need to be considered in the design to ensure that the aluminum forgings do not deform or rupture after expansion due to heating.
Case analysis: An aircraft manufacturing enterprise’s turbine fan engine department produces a fan engine that uses a large number of aluminum forgings. Due to the high-temperature operating environment of the engine, the requirements for high-temperature stability and oxidation resistance of the material are relatively high. The enterprise improved the material preparation, enhanced process control, optimized the design, and strengthened testing and other measures to improve the thermal stability, oxidation resistance, and stress relaxation of the aluminum forgings, enabling the engine components to continue to operate stably in high-temperature conditions and have a longer service life.
