Abstract: A fixture 56 for disposing laser blocking material 52 on the interior of an airfoil 10 is disclosed. Various construction details are developed which allow for the repetitive disposition of the laser blocking material in one airfoil after another. In one embodiment, the fixture includes a sprue plate 62 and locating block 126 which are spanwisely spaced and engage the ends 14, 18 of the airfoil.

Abstract: A method and material 52 for blocking a laser beam L during laser machining is disclosed. The material comprises a thermoplastic polymer. Various details are developed which promote filling and removing the blocking material from a component 10. In one detailed embodiment, the thermoplastic polymer is formed of only carbon and hydrogen and forms harmless effluent during burnout of the material.

Abstract: Method for Depositing a Layer of Abrasive Material on a Substrate Techniques are described for the formation of an abrasive surface layer (14) on an article (12). The surface layer (14) is characterized by a single layer of particles (18) which are evenly spaced apart, in a high density arrangement, within a metallic matrix (16). In the deposition of the particles (18) on the article (12), a vacuum is drawn through a perforated plate (42), wherein the location of each perforation (44) corresponds to the desired location of one particle (18) on the article surface (11). The vacuum holds one particle (18) over each perforation (44) in the plate (42), then the plate (42) is positioned over the article (12) and the vacuum level adjusted so that the particles (18) fall onto the article (12). The matrix (16) is then deposited by plasma arc spraying a superalloy powder. The invention is particularly suited to the formation of an abrasive layer on the tip surface of a blade used in a gas turbine engine.
