Hard anodizing is an important player in the metal coating industry. Also known asMIL-A-8625Type III and engineered anodizing, hardcoat is actually similar to standard anodizing. Both operations are completely controlled, implementing electromechanical processes to achieve specific coating results.

There is a difference, however, and we find that in the fact that hard coat aluminum anodizing creates a much more wear-resistant surface, with a smoother, harder finish. This gives it somewhat of an advantage over standard anodizing.

In the industry, we usually refer to aluminum anodizing by any one of its three types. In the case of hardcoat type 3 in Daytona Beach, available from The Coater, we mean Hardcoat Anodize. This is created under extremely strict conditions, and the resultant finish is much harder, denser, and thicker than you will otherwise find. Moreover, in the quest to keep your metal surfaces abrasion-free, a coating of this type is extremely good at protecting what’s underneath it.

Hardcoat anodizing is distinct from traditional room temperature coating in various ways. We perform it in a sulfuric bath with 180-to-200 grams of acid per liter and, more importantly, a small amount of dissolved aluminum. It’s this additive and the controlled operating temperature of between 28 and 32° F that produces hardcoat’s distinct protective coating. In specific cases, also it’s possible to create an acceptable oxide at slightly higher temperatures.

Current passes through the system for a specific amount of time. Once the system reaches current density, the metal itself forms an oxide of a specific thickness. Finally, it results in a porous oxide, which a professional can color or simply seal off. Limitations on the final color are usually based on the oxide you’re producing and what color you’ve chosen.
