A. The principle of black anodizing

Black anodizing is a method of forming an oxide film on the surface of aluminum. The principle is to soak the aluminum parts in an electrolyte solution containing sulfuric acid and other substances and forms an oxide film with a thickness of about 10 microns on the aluminum surface through electrolysis. This oxide film has a certain hardness and wear resistance, and can also form a layer of black oxide on the surface, to achieve a black effect.

B. Advantages of black anodizing

1. Aesthetics: The surface of the aluminum parts after the black anodizing treatment presents a uniform, delicate, and smooth black color, which not only has aesthetics but also can improve the grade and added value of the product.

2. Corrosion resistance: A layer of oxide film is formed on the surface of aluminum parts after black anodizing treatment. This oxide film has certain hardness and wear resistance, and can also enhance the corrosion resistance of aluminum parts.

3. Enhanced hardness: the surface hardness of aluminum parts after black anodizing treatment can reach HV400-600, which is 1-2 times higher than that of untreated aluminum parts.

4. Environmental protection: The electrolyte used in the black anodizing process does not contain harmful substances and has no pollution to the environment.

5. Low cost: the cost of black anodizing treatment is relatively low, the processing cycle is short, and it can be mass-produced.

C. Application of black anodizing

1. Auto parts: Aluminum alloy parts after black anodizing treatment, such as wheels, door handles, window frames, etc., not only have aesthetics but also can increase the hardness and corrosion resistance of aluminum parts.

2. Electronic products: Black anodized aluminum alloy electronic product casings, such as mobile phones, laptops, etc., not only have aesthetics but also increase the hardness and corrosion resistance of aluminum parts.

3. Building materials: black anodized aluminum alloy building materials, such as window frames, door frames, curtain walls, etc., not only have aesthetics, but also can increase the hardness and corrosion resistance of aluminum parts, and also have UV protection and heat insulation function.

D. Precautions for black anodizing

1. Preparation of electrolytes: the black anodizing treatment requires electrolytes, and the preparation of electrolytes needs to be carried out according to a certain ratio. If the ratio is not correct, the treatment effect will be affected.

2. Control of treatment temperature: Black anodizing treatment needs to be carried out at a certain temperature, and the temperature control needs to be precise, too high or too low will affect the treatment effect.

3. Control of processing time: black anodizing treatment needs to be carried out within a certain period, and the control of processing time needs to be precise, too long or too short will affect the processing effect.

4. Maintenance of equipment: The black anodizing treatment requires some equipment, which needs regular maintenance and overhaul to ensure the normal operation of the equipment and the stability of the treatment effect.

To sum up, black anodizing technology is a widely used and effective surface treatment method, which can improve the aesthetics, corrosion resistance, and hardness of aluminum parts, and is suitable for automobiles, electronics, construction, and other fields. In the process of use, it is necessary to pay attention to the preparation of the treatment liquid, the control of temperature and time, and the maintenance of the equipment.
