Abstract

The present invention describes a composition and method to control dimensional growth during an anodizing process. Potassium permanganate has been discovered, when added to an anodizing solution containing at least one acid, to minimize dimensional change. This novel composition and method were found to be safer, quicker and less expensive than the conventional method of anodizing aluminum. In addition, the novel composition and method were found to have superior properties to aluminum anodized by the conventional method with respect to durability and corrosion resistance. In addition to anodizing, the novel solution described herein is capable of several other uses including the removal of organic and metal contaminants from solution, producing black electroless nickel on a substrate, producing a bright nickel coating on a substrate such as aluminum, and cleaning and activating aluminum for plating.
