Anodizing
Aluminium anodizing is the electrochemical process by which aluminium is converted into aluminium oxide on the surface of a part. This coating is desirable due to the following properties:
- Increased corrosion resistance
- Increased durability/wear resistance
- Ability to be colored through dying
- Electrical insulation
- Excellent base or primer for secondary coatings
The process of anodizing consists of an anodizing solution typically made up of sulfuric acid. A cathode is connected to the negative terminal of a voltage source and placed in the solution. An aluminium component is connected to the positive terminal of the voltage source and also place in the solution. When the circuit is turned on, Aluminium oxide is formed
The thickness o the aluminium oxide “anodized” coating can be varied by processing time – 25 Micron is recommended for heavy duty external permanent architectural application where little deterioration can be tolerated. 15 Micron is recommended for the majority of ordinary architectural requirements. 10 Micron is suitable for internal application and outdoor applications where cleaning is very frequent.
Sealing is the last operation in Anodizing which is a process of blocking pores in the anodic film. It gives surface resistance to straining, abrasion, crazing, and colour degradation.
