Anodizing Condition Process

Generally anodizing process is associated with aluminum metal, but similar process of anodizing can be applied to several kind of base metal like magnesium, titanium, and zinc. Anodizing aluminum can be accomplished in wide variety of electrolytes, employing varying operation condition including concentration and composition of electrolyte. Anodizing can be process in several kind of process, that is used different anodizing bath solution, such as chromic acid process, sulfuric acid process, and oxalic acid anodizing bath. As on the table condition process of anodizing, there are two kind of anodizing process condition. For conventional anodizing and commercial anodizing process.
