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.

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.

Methods for producing a high temperature oxidation and hot corrosion resistant MCrAlX coating on a superalloy substrate include applying an M-metal, chromium, and aluminum or an aluminum alloy comprising a reactive element to at least one surface of the superalloy component by electroplating at electroplating conditions below 100&#xb0; C. in a plating bath thereby forming a plated component and heat treating the plated component.

A fiber-based acoustic treatment material is provided. The material includes between about 3% and about 25% by weight of fibrillated microfibers, between about 20% and about 75% by weight of reinforcement microfibers, and between about 15% and about 60% by weight of a binder. Methods of making the material are also provided.

A protective barrier coating system including a diffusion barrier coating and an oxidation barrier coating and method for use in protecting silicon-based ceramic turbine engine components. A complete barrier coating system includes a thermal barrier coating of stabilized zirconia and an environmental barrier coating of an alloyed tantalum oxide. The oxidation barrier coating includes a layer of metallic silicates formed on a substrate of silicon nitride or silicon carbide to be protected. The oxidation barrier coating can include silicates of scandium, ytterbia or yttrium. The oxidation barrier coating may also include an inner layer of SiONbetween the diffusion barrier and the metallic silicate layer. The oxidation barrier coating can be applied to the substrate by spraying, slurry dipping and sintering, by a sol-gel process followed by sintering, by plasma spray, or by electron beam-physical vapor deposition. The diffusion layer of essentially pure SiNcan be applied to the substrate to prevent the migration of damaging cations from the protective layers to the substrate and is preferably formed by chemical vapor deposition. A method for protecting silicon based substrates can comprise a step of forming an oxidation barrier coating on a substrate, where a step of forming the oxidation barrier includes a step of sintering the oxidation barrier and substrate in a wet gas containing hydrogen.
