Anodizing is an electrochemical process that provides metal surfaces with an oxide layer. This layer stabilizes the surface, preventing the material from oxidizing, whilst also offering durability and resistance to the piece. Furthermore, this oxide layer can be used for aesthetic purposes, as it is pigmented with colors.
What materials can Anodizing be used on?
Although this anodizing process is more common on aluminum parts, it is important to highlight that it can also be carried out on titanium, zinc or magnesium parts.
How does the Anodizing process work?
The process is obtained through an electrochemical relationship. First, the part is submerged in an electrolytic solution, along with another material. This can be a bar of carbon, nickel, lead, stainless steel, or any other conductive material that will not react with the bath.
When current passes through the solution, surface hydrogen and oxygen are released.
Advantages of the Anodizing process
Thin coatings, when compared to paints and powder coatings.
- Highly durable, high hardness and resistance.
- The coating does not peel off.
- Lower costs compared to other processes.
