Abstract: A sealing process includes applying a first reactant to a substrate having a porous structure, the first reactant comprising a chromium (III) precursor and a transition metal precursor and applying a second reactant to the first reactant, the second reactant comprising a rare earth element precursor and an alkaline earth element precursor to form reservoirs of trivalent chromium in pore space of the porous structure, and a physical barrier over the substrate and the reservoirs.

Abstract: A method of coating a metal article is disclosed that includes immersing a metal article having an exterior anodized layer in a bath containing a chemically active corrosion inhibitor, and applying a voltage to the article during the immersing, the voltage driving the chemically active corrosion inhibitor from the bath into the exterior anodized layer. An article is also disclosed that has a substrate comprising a metal, and a porous anodized layer formed on an exterior surface of the substrate that is infiltrated with a chemically active corrosion inhibitor, the anodized layer having an inward-facing region and an outward-facing region, the anodized layer having a greater concentration of chemically active corrosion inhibitors in the inward-facing region than in the outward-facing region.

Abstract: The present disclosure relates generally to a fan blade assembly. In an embodiment, the fan blade assembly includes an airfoil having a forward edge covered by a sheath. The airfoil and the sheath are made from dissimilar conductive materials. A sacrificial anode layer is applied to at least a portion of the sheath so that the sacrificial anode layer will corrode instead of the airfoil.

Abstract: A composite tube may include a body having a longitudinal centerline axis and an end portion having a tapered section and an end rim. At least one of a radially outward edge and a radially inward edge of the end rim may be non-circular. The end rim may be circumferentially continuous. The end rim may be an undulating annulus. A joint assembly may include a support wedge that at least partially engages at least one of a radially inward surface of the end portion and a radially outward surface of the end portion of the composite tube.

Abstract: A powder treatment method includes loading powder into a fluidized bed vessel. At least some of the powder is fluidized in the fluidized bed vessel using an inert gas. While fluidized, the powder is heated in the fluidized bed vessel. A surface treatment coating is then applied to the powder.
