Abstract
A method and shield assembly,for use in processing a flow directing assembly,such as a stator vane or rotor blade, is disclosed. Various details are developed for the construction of the shield assembly and for the method of masking the flow directing assembly. The shield assembly has a shield having two sides,and at least one tab,which extends from one of the sides and through the other side and is pressed against the other side. In one embodiment, the method includes exerting a force against the shield to block movement of the shield from the installed position. The shield assembly might include a locking member for this purpose which has a projection,which is attached to the shield or a locking member,which is not attached to the shield and which has a tab,which engages the shield and a projection,which engages the airfoil. Alternatively, the shield assembly might include a clamp,which presses the shield against the airfoil.
