ABSTRACT:
A turbine engine component (10) with a protective aluminide coating (14) that include additions of silicon and a dopant, such as yttrium and/or hafnium, in an amount effective to reduce sulfidation and a deposition process for forming such aluminide coatings (14). A silicon-containing layer (30) may be applied to the superalloy substrate (12) of the component (10) and the aluminide coating (14) formed by exposing component (10) and layer (30) to a vapor phase reactant containing the dopant. The aluminide coating (14), which contains dopant from the layer (30), may operate as a standalone environmental coating or as a bond coating for an optional ceramic thermal barrier layer (24). An optional zirconia layer (26) maybe provided between the aluminide coating (14) and the ceramic thermal barrier layer (24). Alternatively, the dopant may be included in the silicon-containing layer (30) applied to the component (10) before the aluminide coating (14) is formed and no vapor phase reactant containing the dopant is required.
