  • Coating for Aluminum Alloy Aerostructures
    Publication number: 20260185451
    Abstract: An airfoil element has: an airfoil having a pressure side and a suction side; an aluminum alloy substrate; and a coating system atop the substrate and comprising in at least one location: an anodize layer (24) having a thickness (TA) of 1.0 to micrometer 5.0 micrometers; a sealant (36) filling at least 5.0% of porosity in the anodize layer or at least 0.7% of an apparent volume within a height of the anodize layer; a sealant primer (40) filling 50.0% of porosity in the anodize layer or at least 6.5% of an apparent volume within a height of the anodize layer and extending at least flush to the anodize layer; a second primer (44) over the sealant primer to a of thickness (TS) of 5.0 micrometers to 50 micrometers; and a polymeric coating having a thickness (TT) of 10.0 micrometers to 1.0 millimeter.
