The manufacturing process of aviation forgings usually includes the following major steps: Material preparation: Select the appropriate metal alloy materials, such as titanium alloys, nickel-based alloys, etc. According to the different forging requirements, the raw materials are pre-treated, such as heating, removing the oxide, etc. Pre-forging preparation: Raw materials are cut and heated for subsequent forging processes. The hot forging process is usually used, and the metal material needs to be heated to a certain temperature to improve its plasticity and malleability. Forging: The heated metal material is placed in the forging die and the appropriate pressure is applied. Through the impact, extrusion and deformation in the forging process, the metal material is plastic deformed according to the shape of the mold to form the final forging. Different forging methods such as unidirectional extrusion, axial elongation and transverse expansion can be used in the forging process. Heat treatment: Heat treatment of forgings to improve their structure and properties. Common heat treatment methods include annealing, quenching and tempering. Heat treatment can make the forging grain fine, eliminate stress and defects, and improve its hardness, strength and heat resistance. Machining: Necessary machining of forgings, including cutting, milling, drilling, boring, etc. Through machining, the size and shape are further accurate to meet the design requirements and assembly needs. Surface treatment: The surface of the forging is treated to improve its corrosion resistance and appearance quality. Common surface treatment methods include pickling, shot peening, electroplating, coating, etc. Inspection and quality control: Non-destructive inspection, dimensional measurement and performance testing of forgings are carried out to ensure that their quality meets requirements. Commonly used testing methods include ultrasonic testing, X-ray testing, hardness testing and so on. The above is the general manufacturing process flow of aviation forgings, and the specific process flow will be adjusted and optimized according to the shape, material and use needs of the forgings. The manufacturing process also requires strict compliance with relevant process specifications and quality standards to ensure the reliability and safety of aviation forgings.
