Abstract
Methods and systems for forming modified metal coatings on a gas turbine engine component (20). The gas turbine engine component (20) is placed inside a container (50) having a known volume, along with a source material (32) containing a secondary element. The container (50), gas turbine engine component (20), and the source material (32) inside the container are placed into an oxygen-depleted space (18) inside a reaction chamber (12). At least one temperature for the source material (32) is determined based upon the known volume of the container (50) and an amount of the source material (32). While in the oxygen-depleted space (18), the source material (32) is heated to the at least one temperature sufficient to release a vapor phase reactant (35) containing the secondary element. The vapor phase reactant (35) is confined inside the container (50) at an approximately constant pressure and the secondary element is deposited from the vapor phase reactant (35) as a layer (34) on the gas turbine engine component (20).
