A Complete Guide on Hardcoat Anodizing
Topic: Business
The hardcoat anodizing company specifically uses this process to treat aluminum components that are subjected to heavy-duty wear and tear. Hardcoat anodizing provides smoother and harder finish than standard anodizing ( sun-glo.com/anodizing ). It converts the aluminum part's surface into decorative, extremely durable, and highly corrosion resistant finish.

How does hardcoat anodizing work?

Hardcoat anodizing is a highly controlled oxidation process. In this process, the aluminum part is immersed into a sulphuric acid bath at 32°F, and an electric current is passed through the bath. A cathode is mounted inside the anodizing tank and aluminum acts as an anode. Oxygen ions are released from an electrolyte solution to combine with aluminum atoms to form a layer of aluminum oxide on a surface of the part being anodized. The amount of time aluminum part has been submerged determines the thickness of a coating. This process creates a uniform oxide layer on the surface of the aluminum part.

Advantages of hardcoat anodizing

Hardcoat anodizing has made aluminum one of the most respected and widely used materials in the metal industry. It offers a vast range of advantages. Let’s have a look at a few of them.

Corrosion resistance

Hardcoat anodizing forms highly corrosion resistant finish which protects aluminum part underneath it from weather and moisture. It forms a thick oxide film across the entire surface of the workpiece. Because of its high surface hardness and excellent corrosion resistance, a hardcoat anodizing company uses this process for aluminum parts to be used in marine environments, corrosive atmospheric conditions and harsh environment of space.

Highly durable

Hardcoat anodizing provides an extremely durable surface. As oxide film is fully integrated with the underlying aluminum substrate, resulting surface is highly resistant to peeling, flaking and chipping. Hardcoat anodized aluminum surfaces are very hard and highly resistant to wear and tear and do not peel off easily. Hardcoat anodized aluminum is ten times more wear resistant than ordinary anodized aluminum.

High-quality finishing

Hardcoat anodizing forms a porous layer of aluminum oxide that allows secondary processes such as coloring and sealing. It provides high-quality finishing to aluminum parts. Aluminum parts can be dyed to any desired color.

Maintenance free

Type III anodized aluminum parts are almost maintenance free and easy to clean. Once aluminum components are anodized by a hardcoat anodizing company, there is no huge maintenance and repair required as in the case of other metal finishing processes.

Improve lubricity

Hardcoat anodizing improves the lubrication of aluminum parts significantly. It increases abrasion resistance and provides surfaces that have a high degree of lubricity. This property of hardcoat anodizing makes it ideal for coating of aluminum components ( https://www.sun-glo.com/blog/ ) to be used in industrial machinery.

Cost-effective

Last but not least, hardcoat anodizing is cost-effective coating process. Aluminum oxide is not applied to the aluminum parts like paint or plating, so less equipment and labor required.

If you are also looking for protective finishing of aluminum components, there is nothing that can match hardcoat anodizing, and more importantly, these days hiring a hardcoat anodizing company is not so expensive as well.
