Vacuum heat treatment in aviation field

The aviation industry is a high-tech industry that uses a large number of cutting-edge science and technology, selects various new materials with high specific strength, develops near-zero-residue forming technology, precision and ultra-precision processing technology, etc. In order to ensure the high performance, safety and reliability of aviation products, the aviation system studies and adopts new vacuum heat treatment technologies.

Vacuum heat treatment has obvious advantages

Vacuum heat treatment is a unique overall modification technology. The key components that have undergone vacuum heat treatment can not only ensure the required organization, mechanical properties and process properties, but also deeply tap the potential of key components, ensure and improve the quality and life of key components, and maximize the potential of materials, thereby meeting the technical requirements of long life, high performance and structural weight reduction of key components.

Vacuum heat treatment has the advantages of no oxidation, no decarburization, and can maintain a bright surface. At the same time, it can make parts degreased, degassed, small deformation and easy to automatically control. It adapts to the development direction of precision heat treatment and realizes precision shape and size control and precision organization and performance control. Therefore, vacuum heat treatment technology is widely used in annealing, solid solution, aging and stress relief heat treatment of high-temperature alloys of aviation engines.

In order to solve the heat treatment oxidation and deformation problems of high-strength steel, stainless steel, elastic alloy and other parts of aviation accessories, the best way is to use vacuum heat treatment.

Vacuum heat treatment technologies such as vacuum annealing, vacuum oil quenching, vacuum gas quenching, vacuum tempering, vacuum degassing, vacuum degreasing, and vacuum pressurized gas quenching are already very mature and widely used in production. Research has been completed on the phenomenon of carbon increase in vacuum oil quenching and its prevention, the law of element depletion in vacuum heating, the relationship between vacuum degree and brightness, the determination of cooling rate of vacuum pressurized gas quenching, vacuum heat treatment process and process parameter optimization. Vacuum heat treatment has been used for important load-bearing parts such as aircraft landing gear, beams, joints and engine blades.

Vacuum oil quenching

Vacuum oil quenching is the main process of vacuum heat treatment, which solves the key technical problems of vacuum quenching oil and vacuum oil quenching surface carbon increase. In addition to its application in tool and die heat treatment, it has also been successfully used for precision heat treatment of important structural parts.

Vacuum carburizing

First, vacuum carburizing can satisfactorily solve the problem of removing the passivation film of stainless steel; second, the carburizing temperature is high. Since the heating elements and insulation layers of the vacuum carburizing furnace are graphite and carbon felt, the temperature resistance under vacuum can reach up to 1700℃, so it is easy to achieve high-temperature carburizing. The highest temperature of the advanced vacuum carburizing furnace can reach 1350℃, which can fully meet the temperature requirements of any stainless steel carburizing.
