2. The Finishing Touch: A Complete Guide to Anodizing Process
The “anodizing treatment” referred to in this context is the core of the process. It is an electrochemical method that grows a dense, porous alumina (Al2O3) ceramic film in situ on the aluminum substrate surface.
Standard Process Chain:
- Предварително лечение: Обезмасляване, alkaline cleaning, chemical polishing to prepare a clean, active surface for anodizing.
- Анодиране: The aluminum coil acts as the anode, placed in an electrolyte (e.g., сярна киселина, оксалова киселина) and subjected to electric current, allowing controlled growth of the oxide film on the surface.
- Оцветяване (Не е задължително): Utilizing adsorption (dyeing) or electrolytic coloring techniques to impart rich colors to the oxide film (silver-white, черен, champagne, bronze, и т.н.).
- Уплътняване: Closing the micropores of the oxide film via hot water, пара, or cold sealing agents to maximize its corrosion resistance and stability.
