Understanding the Anodising Process
Anodising is an electrochemical process that thickens the natural oxide layer on the surface of metals, primarily aluminum. The process begins with the metal being immersed in an electrolytic solution, usually sulfuric acid, and an electric current is passed through it. This results in the formation of aluminum oxide, which enhances the metal’s properties.
Key Steps in the Anodising Process
- Surface Preparation: The aluminum surface is cleaned to remove any contaminants or previous coatings.
- Electrolytic Treatment: The prepared part is submerged in an electrolyte bath, where the anodising occurs.
- Dyeing (optional): If a colored finish is desired, the anodised part can be dyed before sealing.
- Sealing: The anodised surface is sealed to enhance corrosion resistance and durability.
