Abstract
A core for investment casting processes includes a core having one or more ceramic materials; and an exterior layer of metal material not susceptible to oxidation under investment casting operating conditions. A method for casting a turbine engine component having an internal passageway includes the steps of forming one or more mold sections each having internal surfaces and at least one of the aforementioned cores for forming one or more turbine engine components having at least one internal passageway; assembling the one or more mold sections; introducing a molten alloy into the one or more assembled mold sections; and consuming the metal of the at least one core during the process.
