As an important engineering material, aluminum alloy fasteners have been widely used in machinery, automobile, aerospace and other fields. In order to meet the requirements of various complex working conditions, these fasteners need to have good wear resistance, corrosion resistance and high strength characteristics. In order to improve these characteristics of aluminum alloy fasteners, micro-arc oxidation surface treatment technology can be used. In this paper, the micro-arc oxidation surface treatment technology of high strength aluminum alloy fasteners will be introduced in detail.
Micro-arc oxidation surface treatment technology is a new type of aluminum alloy surface treatment technology. By generating micro-arc discharge on the aluminum alloy surface, a dense oxide film is formed on the aluminum alloy surface. Compared with the traditional oxidation process, the micro-arc oxidation surface treatment technology has higher hardness, wear resistance, corrosion resistance and binding force of the oxide film.
The micro-arc oxidation surface treatment technology of high strength aluminum alloy fasteners includes cleaning, activation, polishing, oxidation, cleaning and other links. First of all, the aluminum alloy fasteners are cleaned to remove surface dirt and impurities; Then activation treatment was carried out to improve the wettability of the aluminum alloy surface. Then it is polished to make the surface of the aluminum alloy more smooth; After the oxidation treatment, the micro arc discharge is generated on the aluminum alloy surface to form a dense oxide film. Finally, it is cleaned again to remove dirt and impurities from the surface.
The micro-arc oxidation surface treatment technology of high strength aluminum alloy fasteners has the following advantages: improve the wear resistance, corrosion resistance and high strength of aluminum alloy fasteners, and extend their service life; The process is simple, the operation is convenient, the cost is low; Suitable for various shapes and specifications of aluminum alloy fasteners. Micro arc oxidation surface treatment technology has a wide range of application, and can be used in machinery, automotive, aerospace and other fields of high strength aluminum alloy fasteners.
In terms of machinery, micro-arc oxidation surface treatment technology can be applied to the connection and fixing of various mechanical parts, such as bolts, nuts, etc. In automotive, micro arc oxidation surface treatment technology can be applied to the manufacture and maintenance of various automotive parts, such as engines, chassis, etc. In aerospace, micro-arc oxidation surface treatment technology can be applied to the manufacture and maintenance of various aerospace spacecraft, such as aircraft, rockets and so on.
In short, the micro-arc oxidation surface treatment technology of high-strength aluminum alloy fasteners has the advantages of improving wear resistance, corrosion resistance and high strength, and has a wide range of application prospects. With the development of science and technology, the technology will have more development and application.
