-Sulfuric Acid Anodizing- Acid Recovery with Diffusion Dialysis What is Sulfuric Acid Anodizing? The Anodizing process produces oxide film on the surface of an aluminum substrate. This acid film produces a hard corrosion and abrasion resistant coating, with excellent wear properties. Various electrolyte solutions can be employed, but the most commonly used is Sulfuric acid. By controlling the electrolyte and the anodizing conditions, such as temperature, current density and air agita- tion, one can produce Aluminum coatings with almost any desired property. Why should I use Diffusion Dialysis with my Sulfuric Acid Anodizing process? Diffusion Dialysis is ideally suited for the recycling of sulfuric acid anodizing solutions. Diffusion Dialysis provides improved anodize quality, c
