  • Coated component and method of preparing a coated component
    Patent number: 11092019
    Abstract: A coated component and a method of preparing a coated component are provided. The method comprises providing a substrate; and applying a dual coating system to the substrate. The applying of the dual coating system includes applying a diffusion barrier coating; and applying a corrosion-resistant coating. The corrosion-resistant coating comprises a greater concentration of silicon and aluminum than the diffusion barrier coating, and the dual layer coating system includes an aluminide interdiffusion zone.
    Type: Grant

  • ALUMINIDE COATING SYSTEM AND PROCESSES FOR FORMING AN ALUMINIDE COATING SYSTEM
    Publication number: 20180209045
    Abstract: A process for forming an aluminide coating system on a substrate. The process includes preparing a slurry including, by weight, about 35 to about 65% of an aluminum donor powder, the aluminum donor material comprising at least 35% aluminum, about 1 to about 25% of a binder, and balance essentially carrier. The slurry is applied to the substrate. The substrate is a nickel or cobalt based superalloy being essentially free of aluminum. The slurry is heated to form an aluminide diffusion coating including an additive aluminide layer and an interdiffusion zone disposed between the substrate and the additive aluminide layer.
