The stable operation of power supply equipment relies on the performance support of metal components. As a core process for the surface treatment of aluminum and aluminum alloys, the anodic oxidation reaction plays a key role in the shells and core accessories of power supplies by virtue of its ability to form a dense oxide film. The anodic oxidation reaction endows aluminum components with multiple advantages of corrosion resistance, insulation and wear resistance through electrochemical regulation, adapting to the use requirements of power supplies under different working conditions. At the same time, the application of this process needs to control many details to give full play to its value.
1. Core Applications of Anodic Oxidation Reaction in Power Supplies
The application of the anodic oxidation reaction in the power supply field focuses on the performance enhancement of aluminum structural parts, which is an important means to improve the durability and adaptability of power supplies. Most power supply shells are made of aluminum alloy. After the anodic oxidation reaction, a dense aluminum oxide film is formed on the surface, which can effectively resist dust, water vapor and corrosive media in the industrial environment, keeping the shell structurally stable under high-temperature and dusty working conditions. At the same time, the oxide film formed by the anodic oxidation reaction also has good heat dissipation, which does not affect the heat dissipation inside the power supply and adapts to the heat dissipation requirements of the power supply.
The anodic oxidation reaction is also indispensable for the precision metal accessories of power supplies. Such accessories have high requirements for insulation and wear resistance. The oxide film created by the anodic oxidation reaction can improve the electrical insulation performance of the accessories, avoid circuit short circuit problems, and enhance the surface hardness to reduce the wear of the accessories during use. In special equipment such as anodic oxidation power supplies, the process parameters of the anodic oxidation reaction are more matched with the output characteristics of the power supply. Through precise current and voltage regulation, the film formation efficiency and film quality of the anodic oxidation reaction can be optimized. In the R & D of power supply related products, YIBENYUAN also integrates the process characteristics of the anodic oxidation reaction into the treatment of metal components, making the products suitable for more industrial use scenarios.

2. Key Precautions for the Application of Anodic Oxidation Reaction in Power Supplies
The application effect of the anodic oxidation reaction depends on the precise control of process parameters, which is an indispensable point in the treatment of power supply metal components. When carrying out the anodic oxidation reaction, it is necessary to adjust the electrolyte ratio and current density according to the use scenario of the power supply components. For the power supply shell used outdoors, the film formation thickness of the anodic oxidation reaction should not be less than 15μm, and the sealing treatment should be done after completion, so that the corrosion resistance of the oxide film meets the standard of more than 96 hours of salt spray test, avoiding the impact of pores in the film layer on the protection effect.
The pre-treatment and post-treatment links of the anodic oxidation reaction also need to be strictly controlled. The pre-treatment should completely remove the oil and natural oxide layer on the surface of aluminum components, otherwise the anodic oxidation reaction will cause uneven film formation and affect the performance of the components. The post-treatment sealing process should be selected according to the needs of the components, and the operating parameters of high-temperature sealing or low-temperature sealing should be adapted to the film characteristics of the anodic oxidation reaction. In addition, the processing environment of the anodic oxidation reaction needs to be kept clean to prevent impurities from entering the electrolyte and affecting the reaction process, ensuring that the performance and precision of the power supply metal components can meet the use requirements of power supply equipment after the anodic oxidation reaction treatment.
