摘要： Ionic liquid bath plating systems, methods, and plating anodes are provided for depositing metallic layers over turbomachine components and other workpieces. In an embodiment, the method includes placing workpieces in a plurality of cell vessels such that the workpieces are at least partially submerged in plating solution baths, which are retained within the cell vessels when the plating system is filled with a selected non-aqueous plating solution. After plating anodes are positioned adjacent the workpieces in the plating solution baths, the plurality of cell vessels are enclosed with lids such that the plurality of cell vessels contain vessel headspaces above the plating solution baths. A first purge gas is then injected into the plurality of cell vessels to purge the vessel headspaces. The workpieces and the plating anodes are then energized to deposit metallic layers on selected surfaces of the workpieces utilizing an ionic liquid bath plating process.

摘要： Ionic liquid bath plating methods for depositing aluminum-containing layers utilizing shaped consumable aluminum anodes are provided, as are turbomachine components having three dimensionally-tailored, aluminum-containing coatings produced from such aluminum-containing layers. In one embodiment, the ionic liquid bath plating method includes the step or process of obtaining a consumable aluminum anode including a workpiece-facing anode surface substantially conforming with the geometry of the non-planar workpiece surface. The workpiece-facing anode surface and the non-planar workpiece surface are positioned in an adjacent, non-contacting relationship, while the workpiece and the consumable aluminum anode are submerged in an ionic liquid aluminum plating bath. An electrical potential is then applied across the consumable aluminum anode and the workpiece to deposit an aluminum-containing layer onto the non-planar workpiece surface. In certain implementations, additional steps are then performed to convert or incorporate the aluminum-containing layer into a high temperature aluminum-containing coating, such as an aluminide coating.
