Problems solved by technology

[0005] Regardless of the process, the pollutants on the surface of the workpiece are often not completely removed, and the residual pollutants are likely to cause premature corrosion and rust of the product
[0006] At the same time, the existing workpieces are not subjected to other surface treatment after cleaning, and the workpieces are vulnerable to the intrusion of water and other liquids to cause corrosion, and their corrosion resistance is poor, which seriously affects the service life of the workpieces

Abstract

The invention discloses an anti-corrosion surface treatment method of a coil shell and a corrosion-resistant coil shell, wherein the surface treatment method includes the following steps: S100, cleaning the coil shell; S200, performing plasma cleaning on the cleaned coil shell; S300, performing plasma cleaning on the coil shell; A solid corrosion-resistant film is formed on the surface of the cleaned coil shell through vapor deposition, and the contact angle of liquid on the surface of the solid corrosion-resistant film is greater than 90°. The method is exquisite in design and simple in process. The surface of the workpiece can be cleaned by plasma through the vapor deposition system, thereby ensuring the cleanliness of the surface of the workpiece, and at the same time improving the surface activity of the workpiece, further forming a solid corrosion-resistant film on the surface of the workpiece, and making the solid corrosion-resistant film Maintaining hydrophobicity can effectively avoid the intrusion of liquid, greatly improve the corrosion resistance of the workpiece, and prolong the service life of the workpiece, especially suitable for the treatment of workpieces with high surface anti-corrosion requirements.

Description

technical field [0001] The invention relates to the field of coil shell processing, in particular to an anti-corrosion surface treatment method for a coil shell and a corrosion-resistant coil shell. Background technique [0002] At present, for the finished coil casing (coil casing for automobile turbocharger), it usually needs to be cleaned before packaging. [0003] One of the feasible cleaning processes includes the following process: ultrasonic cleaning-rinsing-industrial oven drying. [0004] Another feasible cleaning process includes the following processes: automatic spray cleaning - ultrasonic cleaning - spray rinsing - high pressure wind cutting water. [0005] Regardless of the process, the pollutants on the surface of the workpiece are often not completely removed, and the residual pollutants are likely to cause premature corrosion and rust of the product. [0006] At the same time, the existing workpieces are not subjected to other surface treatment after clean...
