    摘要: A base metal repair tape includes a first layer formed braze alloy bonded together with fibrillated polytetrafluoroethylene, a second layer formed from powdered base metal bonded together by fibrillated polytetrafluoroethylene and a third layer comprising a brazing alloy bonded together by fibrillated polytetrafluoroethylene. This is used to repair base metal by placing the first layer on the base metal and brazing the base metal powder so that the brazing alloy melts and diffuses into the base metal powder bonding it to the surface of the article. This permits the braze powder to be bonded to the base metal surface with minimal distance between the base powder particles. The number of alternating layers of base metal and braze alloy can be increased to increase the thickness of the repair. This can also be used to form small intricate parts.

    摘要: A method for repositioning or repairing holes in metal substrates such as metal components used in jet engines and the like. The hole to be repositioned or repaired is enlarged and a recess is formed at each end of the enlarged hole. A deformable metal insert is then inserted within the enlarged hole and then subjected to physical forces so as to cause it to deform and frictionally engage the walls of the recesses and the enlarged hole so that the insert becomes axially fixed therein. A new, repositioned hole can then be formed in the fixed insert that extends completely therethrough.

    摘要: A method for repairing a discrete damaged part of a strip bonded to an article surface includes applying a first removable masking member along and adjacent the damaged part of the strip and separated from the strip by a gap of at least 0.005″, and applying a second removable masking member to the outer surface of the strip. A repair adhesive, which can be cured at a curing temperature less than a higher temperature which can result in damage to properties of the article or a surface coating, is applied at and beneath an edge of the damaged part of the strip. Then the repair adhesive is cured at the curing temperature. Apparatus for bonding a strip to an end portion of the article includes a body having a channel there through defined, in part, by spaced apart support surfaces for article surfaces and positioned relative one to the other at a relative spatial position substantially coinciding with the relative spatial position of the article surfaces. The support surfaces include surface profiles substantially reproducing surface profiles of the article surfaces.

    摘要: An article having a design external aerodynamic shape includes a body with a body external surface and an outer portion external surface of an outer portion bonded with a part of but less than substantially all of the body surface. The external surfaces of the body and outer portion each define less than the design external aerodynamic shape. However, together they define such shape. The article is made by selecting the design external aerodynamic shape from an existing article having a first body and a first outer portion. A replacement outer portion is selected in an amount less than the first outer portion and bonded with a region less than substantially all of a replacement body external surface. The replacement body has a replacement body external surface and replacement body external shape different from the first body substantially by that amount. The replacement body is made with the replacement body external shape. Then the replacement outer portion is bonded with the region of the replacement body external surface. The result is that the external surfaces of the replacement body and replacement outer portion together define the design external aerodynamic shape.

    摘要: A method is disclosed for repairing damage to an airfoil. The method provides for the removal of a section of the airfoil that substantially encompasses the damaged area, which consequently leaves a void and a cut-away surface in the airfoil. A replacement piece larger than the residual void is provided for use in replacing the section removed from the airfoil. A joining operation welds or otherwise joins the replacement piece to the airfoil at the cut-away surface to form a joined airfoil. The joined airfoil has a seam between the airfoil and the replacement piece. At least a portion of the seam is processed by laser shock peening to induce compressive residual stresses therein.

    摘要: A damaged turbine rotor wheel dovetail is repaired by cutting off the annular dovetail and welding a new forged ring onto the remaining wheel body. Fine-line welding is accomplished by inserting welding apparatus into grooves opening through axial faces of the wheel body and ring and rotating the rotor to provide multiple welding passes. Periodic ultrasonic inspection of the welds is provided by applying an ultrasonic transducer to the periphery of the ring to detect defects in the weld. To enable the transducer to operate at high welding temperatures, a manifold is disposed about the transducer defining a coolant cavity. Cooling medium is supplied the coolant cavity to maintain the transducer operable within predetermined temperature operating limits.
