Abstract:
1. A deposition method for use with a gas turbine engine component, the method comprising: placing the gas turbine engine component inside a container having a known volume; placing a source material configured to release a vapor phase reactant when heated to a vaporization temperature inside the container, the vapor phase reactant containing a secondary element; placing the container, the gas turbine engine component, and the source material into a space that is then depleted of oxygen; determining at least one temperature for the vapor phase reactant based upon the known volume of the container, an amount of the source material, and a targeted pressure of the vapor phase reactant inside the container; while the container is in the oxygen-depleted space, heating the source material to the at least one temperature greater than the vaporization temperature to release the vapor phase reactant; controlling the temperature of the vapor phase reactant while confining the vapor phase reactant inside the container to maintain the vapor phase reactant inside of the container approximately constant at the target pressure; and depositing the secondary element from the vapor phase reactant as a layer on an exterior surface of the gas turbine engine component.
