Anodizing
The anodizing process provides an artificial protection to the aluminum with its own corrosion.
Anodizing is an electrochemical process that creates a protective coat of aluminum oxide on the base surface. This process consists in submerging the aluminum in acid (sulphuric acid). When an electric current is applied, oxygen is liberated and reacts with the aluminum anode generating a oxide coat that will vary depending the tim the current is applied. In order to close the pores on the aluminum surface, it is soaked in desmineralized water at 96°C. In this way, the process ends, and the life span of the finish is proportional to the thickness of the coat.
Aluminum oxide can reach great hardness, ranging between 7 and 8 in the Mho Scale. It is very stable and resistant to environment corrosion agents.
The coat generated in this electrochemical process is imbedded in the metal and therefore cannot be scraped or peeled off.
Advantages
- Maintenance free.
- Increases the protection against rain, sun and humidity.
- Increases superficial hardness.
- Decorative finish, different tonalities obtained.
- Resistance to wear and tear.
- Oxide resistance.
