What should be noted for surface treatment in precision aviation parts processing?

In precision aviation parts processing, surface treatment is a crucial step that directly affects the wear resistance, corrosion resistance, fatigue resistance, and other properties of the parts. The following are several points to note when performing surface treatment in precision aviation parts processing: 1. Choose the appropriate surface treatment method: Select the appropriate surface treatment method based on the material, usage requirements, and processing technology of the part. For example, for aluminum alloy materials, anodizing or chemical oxidation methods can be used; For stainless steel materials, shot peening or nitriding treatment can be used. Controlling surface treatment parameters: The control of surface treatment parameters is crucial as it determines the surface quality after treatment. Strictly follow the process requirements and set reasonable parameters such as processing temperature, time, pressure, etc. to ensure the surface treatment effect. 3. Ensure the cleanliness of the workpiece surface: Before surface treatment, it is necessary to ensure that the workpiece surface is free of impurities such as oil stains, rust, and oxide scales, otherwise it will affect the treatment effect. Cleaning, rust removal, and other methods can be used to achieve the required surface condition of the workpiece. 4. Pay attention to the protection of parts after surface treatment: Parts after surface treatment should be properly stored to avoid collisions, scratches, and other situations. For some parts that require rust prevention treatment, rust prevention treatment should be carried out according to requirements, and regular inspections and maintenance should be carried out. 5. Strengthening quality inspection and control: It is necessary to conduct quality inspection and control on parts after surface treatment. Various testing methods can be used, such as visual inspection, hardness testing, metallographic analysis, etc., to ensure that the surface treatment quality meets the requirements. 6. Improving the skill level of operators: The skill level of operators has a direct impact on the quality of surface treatment. Regular training and assessment should be provided to operators to improve their skills and ensure that they are proficient in various surface treatment techniques and process requirements. 7. Strengthen equipment maintenance and upkeep: Surface treatment equipment is the foundation for ensuring surface treatment quality. Regular maintenance and upkeep should be carried out on the equipment to ensure its normal operation and improve its service life and stability.
