Abstract: A substrate is protected by a multilayer protective coating (72) having an oxide layer (76), and a phosphate/organic binder layer initially overlying the oxide layer (76). The multilayer protective coating (72) is cured by first degassing the multilayer protective coating (72) in a pre-cure degassing temperature range of from about 250°F to about 500°F for a time of at least about 30 minutes. The multilayer protective coating (72) is thereafter heated to a curing temperature range of from about 1200°F to about 1400°F for a time of at least about 30 minutes.

Abstract: A gas turbine component (30), such as a turbine disk (36, 40) or a turbine seal element (44, 46, 48), is protected by depositing an oxide coating (60) on the gas turbine component (30). The deposition is performed by a vapor deposition process such as metal-organic chemical vapor deposition (MOCVD) to a coating thickness of from about 0.2 to about 50 micrometers, preferably from about 0.5 to about 3 micrometers. The deposited oxide may be an oxide of aluminum, silicon, tantalum, titanium, and chromium.
