摘要： 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 Si2ON2 between 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 Si3N4 can 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.

摘要： A plurality of powders is admixed to form a substantially homogenous powder mixture comprising each of the alloy elements. At least one of the powders consists essentially of a substantially pure elemental metal. The substantially homogenous powder mixture is cold gas-dynamic sprayed on the substrate to form a coating of the alloy elements. The coating is then heated until the alloy elements inter-diffuse and form the alloy. In an exemplary embodiment, the substantially homogenous powder mixture includes stoichiometric amounts of each of the alloy elements, and each of the powders consists essentially of a substantially pure form of one of the alloy elements.
