Abstract: A method and shield assembly 12 for use in processing a flow directing assembly 10, 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 52, 56 and at least one tab 56 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 106a which is attached to the shield or a locking member 42 which is not attached to the shield and which has a tab 114 which engages the shield and a projection 112 which engages the airfoil. Alternatively, the shield assembly might include a clamp 92 which presses the shield against the airfoil.

Abstract: A locking member for engaging a shield 40 which is disposed during processing about an airfoil 24 of a flow directing assembly 10, such as a stator vane or rotor blade, is disclosed. Various details are developed for the construction of the locking member. In one embodiment, the locking member is separate from the shield and has projections 112, 116 that each engage an opening 36a, 36b in the airfoil and tabs 114, 118 which engage an opening 78, 84 in the shield. In another embodiment, the shield has a projection 106a which is attached to the shield.
