Description

Technical Field

[0001] The present invention relates to the technical field of metal surface treatment, and in particular to a surface treatment process method for a multi-energy field composite high-precision structural part. Background Art

[0002] Surface treatment is the process of artificially creating a layer on the surface of a base material with mechanical, physical, and chemical properties that differ from those of the base material. The goal of surface treatment is to meet the product's requirements for corrosion resistance, wear resistance, decorative properties, or other special functions. High-precision structural components, an indispensable component of numerous high-tech products, are widely used in communications equipment, new energy, automotive, consumer electronics, aerospace, industrial automation, and other fields. These components have higher performance requirements than ordinary metal materials. Therefore, finding the most suitable surface treatment methods for high-precision structural components is particularly important.

[0003] Due to various limitations, traditional surface treatment methods for high-precision structural parts are no longer able to meet the current high-efficiency, high-quality surface treatment requirements for high-precision structural parts. Other existing methods also suffer from technical deficiencies such as high surface roughness after treatment. Due to the use of a single energy field for surface treatment, it is difficult to achieve a balanced balance between efficiency, precision, and surface microscopic quality in the preparation of high-precision structural parts after surface treatment. Furthermore, corrosion resistance and wear resistance require further improvement.

[0004] To address the aforementioned issues, Chinese invention patent application number 201911196610.2 discloses a surface treatment method for the Audi C8's chassis components. The method comprises four steps: framing the chassis components and subjecting them to ultrasonic degreasing and flip cleaning; transferring the cleaned chassis components to a passivation tank and flipping them for passivation; flipping and spray rinsing the passivated components; and vacuum drying the cleaned components. The method achieves excellent treatment results, is easy to operate, and consumes low energy, saving energy and shortening production time. However, the surface quality of the components obtained by this surface treatment method still needs to be further improved, as does their corrosion and wear resistance.

[0005] Therefore, the development of a multi-energy field composite high-precision structural parts surface treatment process method meets market demand, has broad market value and application prospects, and is of great significance to promoting the development of multi-energy field composite surface treatment technology.
