Abstract

Method to facilitate vapor phase coating of turbine airfoils. A dovetail receptacle receives the dovetails of a plurality of airfoils. The airfoils are separated by spacers with the airfoil dovetails sealed in a chamber of the receptacle to facilitate vapor phase coating of airfoil flowpath surfaces and platform upper surfaces of several airfoils simultaneously while masking the dovetail sections.
