ABSTRACT:
Apparatus and method for simultaneously coating interior and exterior surfaces of articles, such as advanced turbine airfoils, the interior surfaces defined by narrow, complex passageways. The apparatus and method, in addition to providing for simultaneous coating of interior and exterior surfaces, also permits additional control over the coating process by permitting control over the partial pressure of reactive gas introduced into the reaction chamber. The apparatus also permits for subsequent thermal treatment of the coated parts in an inert gas atmosphere with no intermediate cooling step thereby reducing costs while eliminating the potential for damage due to handling by the elimination of at least one handling operation.
