The hard anodizing process, or hard coat anodizing, is a specialized surface coating treatment that greatly enhances the material properties of aluminum, especially for aluminum-made products, parts, and components used in government and defense-related applications. Hard anodizing is achieved through an electrochemical reaction that increases the thickness of the naturally occurring oxide layer on aluminum surfaces. The process can create a relatively thick layer of hard aluminum oxide on the surface, allowing a coating thickness of up to 75 microns. The hard anodizing process, called Type III anodizing, is the standard for government and defense contracts that meets U.S. military specification Mil-A-8625  standards.  Continue Reading
