Aluminum Hardcoat Anodizing
Service Detail from Anoplate Corporation
The hardcoat anodize process can be accomplished through Black Fluorocarbon, Silver Impregnate or Anolube III. AnoLube III provides manufacturers with the low weight and low cost advantages of aluminum, the abrasion resistance of hardcoat anodize, and the lubricity of Teflon®. RIT's Formula SAE car included Anoplate's hard coat anodize applied to several components of the power train. The RIT car was chosen to participate in further international competition, where it was one of the top finishers. Its use on this car is proof positive of its resistance to abrasion.
Anoplate Processes: AnoLube III
AnoLube III provides manufacturers with the low weight and cost advantages of aluminum, the abrasion resistance of hardcoat anodize, and the lubricity of Teflon®.
Under this special process, Teflon® penetrates the surface of a precision hardcoat-anodized component. The resulting surface is highly corrosion resistant. It exhibits dielectric properties superior to conventional hardcoat anodize, and it retains the non-stick, low coefficient of friction provided by Teflon®.
AnoLube III meets the requirements of MIL-A-8625 for Type III coatings, MIL-A-63576, AMS 2468, and other industrial specifications.
Benefits of the process vary depending on the alloy, the coating thickness, and the original surface finish. Any aluminum alloy can be processed, but those without copper and silicon content typically produce the best results.
Most applications involve a 2-mil (50 micron) coating. Roughly half of that thickness penetrates into the original surface, so actual surface growth on a 2-mil coating is only about 1 mil. Because AnoLube III penetrates the surface, it will never chip, blister, or peel.
- Low coefficient of friction
- Low wettability, non-stick Teflon® surface
- Abrasion-resistant, "file hard" aluminum oxide
- Corrosion-resistant hardcoat with chemically inert Teflon®
