DESCRIPTION, INNOVATION AND ADVANTAGES

Low-wear anodized aluminum is invented by impregnating anodized surfaces with specific fillers for industrial applications such as pistons, bearings, rails and other rubbing parts in mechanical systems. Hard (Type III) anodizing of aluminum alloys is developed to produce nanoporous anodic coatings with thicknesses up to 100 μm or higher. Industrial aluminum alloys of 6000 and 7000 series are most preferable for anodizing. Anodized aluminum surfaces are impregnated with our patented AlumaShield coating, which is able to penetrate into the nanopores of anodic coating. Unlike barrier coatings, impregnated fillers within the nanopores can migrate into the friction zone thus reducing wear of the anodized aluminum surfaces. AlumaShield Impregnated surfaces also demonstrate high thermal stability up to 160°C. Combining the aluminum alloy and AlumaShield filler can improve the tribological performance of anodic coatings 20 times or more compared to commercial lubricants.
