An apparatus (10) for applying a thermal spray coating onto a substrate (24) includes a chamber (16) having an open bottom portion (18), a gas source for releasing a gas lighter than oxygen into the chamber (16) and displacing the oxygen from the chamber (16), and a spray gun (30) for spraying coating through the gas in the chamber (16) and onto the substrate (24). A method is also provided including the steps of displacing oxygen from the chamber (16) with the gas, and spraying the coating through the gas and onto the substrate (24) disposed within the chamber, the gas preventing oxidation between the substrate (24) and layers of the coating. <IMAGE> |
