Abstract
A fixture (90) for use in selectively applying a protective coating to a gas turbine engine blade (10) includes a base (92) having a blade retention slot (102), and a disposable shield (110). The shield (110) includes a sheet metal sleeve (112) and a cap (114) having a window (116) the cap being affixed to one end of the sleeve. When fully assembled with the blade properly positioned in the fixture only those portions of the blade selected to be coated are exposed. Additional features such as a locator dowel (104) extending from the floor of the slot and mutually cooperative track (121) and nub (122) assist in locating the blade correctly in the fixture and orienting the window with respect to the blade platform (16). A lock exemplified by a groove (128) and the nub (122) resists separation of the shield from the base during coating operations.
