1. Anodizing tank setup: The electrolytic cell is responsible for the entire electrolysis process and it is where the aluminum and cathode are immersed in the electrolytic cell. The electrolytic cell is usually made of chemically resistant materials such as polypropylene, PVC or coated stainless steel. To fix the anodes, the electrolytic cell comprises a rack mechanism which is further connected to the electrical busbar for a uniform and controllable power supply. On the other hand, a separate fixture holds the cathode and is connected to the busbar. During the anodizing tank setup, you need to consider different factors; the size of the tank, the busbar capacity and its safe connection to the rack, the cathode to anode area ratio (1:1 or 1:3), the filtration of electrolyte impurities, etc.

2. Control of acidic solution: The temperature and concentration of the acidic solution directly affect the thickness and quality of the anodized layer. High acid concentration may lead to faster layer growth, but will result in a rougher or burned surface. Therefore, you need to monitor the pH value of the solution. If any changes occur, you can add buffer solution or neutralizing solution according to the standard pH value set for the process.

3. Manage anodized layer and thickness: The anodized layer is formed when oxygen ions in the electrolyte migrate to the metal surface and react with metal atoms. Therefore, layer growth and thickness fundamentally depend on factors that affect the metal and oxygen ion concentrations. For example, temperature, current density, time, acid concentration, etc. Therefore, you must set all processing parameters taking into account thickness requirements and other surface finish characteristics.

4. Anodizing Tank Maintenance: As anodizing progresses, the bath begins to accumulate impurities such as metal salt residues and dissolved chemicals. In addition, metal ion concentrations tend to be higher than standard levels (ideally less than 20 g/L). These impurities affect process efficiency and overall quality. Therefore, filtering impurities and maintaining pH, proper agitation, and ion concentration are critical.

1. Preparation and cleaning: A uniform and smooth surface is essential for the application of the anodized layer. You can achieve this through mechanical treatment and chemical cleaning. Mechanical surface treatment such as grinding and polishing that remove surface irregularities and defects. While alkaline or acid cleaning removes grease, oil, dirt and any other contaminants, followed by rinsing with deionized water to remove residual cleaning agents. Therefore, etching can be further cleaned to peel off the thin surface layer and create a uniform matte effect.

2. Electrochemical process: The part to be anodized next becomes the anode, and the other highly conductive metal becomes the cathode, and both are immersed in the electrolytic cell. When current flows through this electrolytic device, the anode oxidizes and loses electrons. During the electrolysis process, the metal surface is oxidized to form a dense oxide film. This oxide film is very hard and can protect the metal from further corrosion.

3. Coloring (optional): After the oxide film is formed, it can be dyed to give the metal surface a different color.

4. Sealing: The corrosion resistance and wear resistance of the oxide film can be further enhanced by sealing.

Anodizing is a surface treatment method that forms a thin protective oxide layer on the surface of the substrate through an electrochemical process to achieve a smooth and uniform surface treatment, with a roughness value (Ra) as low as 0.5µm. Anodizing can improve the firmness, corrosion resistance, wear resistance and aesthetics of aluminum alloy, magnesium alloy and titanium alloy accessories.

Anodizing has a wide range of applications and is widely used in various industries such as medical devices, electronic communications, automotive accessories, aerospace, agricultural machinery, etc.
