How To Anodize Aluminum Blue. But the characteristics of that film will vary. This is important for the removal of impurities that can hinder the process.
The aluminum acts as an anode, so that oxygen ions are released from the electrolyte to combine with the aluminum atoms at the surface of the part being anodized. Before beginning the process, one should calculate the liters or gallons of solution needed, while taking into account the recommended ratio of acid in the anodizing bath (15% to 18%). Next, we seal the anodize simply by rinsing it with water or other chemicals, depending upon your needs.
The anodizing is a porous structure that grows out of the base aluminum and absorbs colored dye very well.
First, cleaning of the aluminum part occurs before undergoing anodization. The anodizing is a porous structure that grows out of the base aluminum and absorbs colored dye very well. This is important for the removal of impurities that can hinder the process. The aluminum can also be dyed at the end of the anodizing process to get a cosmetic, colored finish.
