Patent number: 11559847Abstract: A method for repairing a part and the resulting is disclosed. The method includes positioning a plug having an inner braze element coupled thereto into a cavity defined by an internal surface of a component. The cavity has a circular cross-section at the external surface of the component. The plug completely fills the circular cross-section and the inner braze element is within the cavity. A braze paste is positioned at least partially around the plug at the external surface. The component is positioned such that the inner braze element is above the plug. The component is subjected to a thermal cycle to melt the inner braze element around the plug, completely sealing the cavity by forming a metallurgical bond with the plug and the internal surface of the component. During the thermal cycle the braze paste is melted to form a metallurgical bond with the plug and external surface.Type: GrantFiled: January 8, 2020Date of Patent: January 24, 2023Assignee: General Electric CompanyInventors: Yan Cui, Michael Douglas Arnett, Matthew Joseph Laylock, Brian Lee Tollison, Jeffrey Michael Breznak

Patent number: 9969000Abstract: A method of fabricating a joining preform includes the step of printing a self-fluxing joining alloy. Joining includes brazing and soldering. The self-fluxing joining alloy contains at least one of phosphorus, boron, fluorine, chlorine, or potassium. Another printing step prints a non-phosphorous joining alloy. Both printing steps are performed by an additive manufacturing or 3D printing process. The printing a self-fluxing joining alloy step may be repeated until the non-phosphorous joining alloy is substantially encapsulated by the self-fluxing joining alloy. The self-fluxing joining alloy may be a BCuP alloy, a CuP alloy, a CuSnP alloy, a CuSnNiP alloy or a CuAgP alloy. The non-phosphorous joining alloy may be a BAg alloy, a BNi alloy or a BAu alloy.Type: GrantFiled: July 8, 2015Date of Patent: May 15, 2018Assignee: General Electric CompanyInventors: Andrew Batton Witney, Jeffrey Michael Breznak

Patent number: 9103035Abstract: A coating system and processes by which the coating system can be deposited on a surface region of a component to be resistant to erosion, and particularly resistant to erosion caused by high moisture content environments. The coating system includes a diffusion barrier layer, an intermediate layer overlying the diffusion barrier layer, and an outermost layer overlying the intermediate layer. The diffusion barrier layer is capable of inhibiting diffusion of damaging elements therethrough. The intermediate layer is an erosion-resistant material, having a hardness that is greater than the diffusion barrier layer, and being deposited by a near-net-shape laser deposition process. The outermost layer is erosion-resistant material, having a hardness that is greater that the hardness of the intermediate layer. The intermediate layer has a thickness of greater than the diffusion barrier layer and the outermost layer.Type: GrantFiled: April 10, 2013Date of Patent: August 11, 2015Assignee: General Electric CompanyInventors: Swami Ganesh, Jeffrey Michael Breznak
