Abstract: A method for counteracting tensile stress in an article is disclosed, including heating the article and applying compressive stress to the article along a compressive stress vector, the compressive stress vector including a compressive stress vector component opposite in direction to a tensile stress vector of a thermally-induced tensile stress of the article. The compressive stress is applied by thermally-induced autogenous pressure by a fixture contacting the article. A fixture for counteracting tensile stress is disclosed, including a first compression member and a second compression member, and a position lock connecting the first compression member to the second compression member and reversibly fixing the first compression member relative to the second compression member. The first compression member and the second compression member include compressive surfaces having mating conformations for surfaces of an article. The position lock includes a material composition.

Abstract: A method for masking cooling passages of a turbine component having an external surface, an internal cavity for receiving cooling air, and cooling passages extending therebetween. The location and angle of cooling passages are determined using a robotic arm and a location system. A masking device is placed in the cooling passages located during the locating step. The masking device includes a head portion having a gripping feature for gripping by a robotic arm, and a locating feature for orientation of the masking device by the robotic arm. A retaining portion extending from the head portion is arranged and disposed to retain the masking device in a cooling passage. The retaining portion is narrower proximate a distal end than proximate the head portion. The component and head portion of the masking devices are coated. The masking devices may be removed using the robotic arm and locating system.

Abstract: A coupon for repairing a part is disclosed. The coupon includes an outwardly threaded body configured to mate with an inwardly threaded opening in a damaged area of the part. The part and/or coupon may include a superalloy. The threaded arrangement converts tensile stresses into shear stresses that allow the repair to exhibit material characteristics as good as or better than the superalloy. A method of using the coupon to repair a part using brazing, and a turbomachine part using the coupon, are also disclosed.
