Abstract: Embodiments of the present disclosure provide turbine buckets, turbomachinery, and related methods for identifying bucket deformation. A turbine bucket according to embodiments of the present disclosure can include an airfoil extending radially from a base, relative to a rotor axis of a turbomachine; and a magnetized material coupled to the airfoil proximal to a radially outer end thereof. To identify bucket deformation, a magnetic sensor can measure a magnetic field strength of the magnetized material, and a computing device in communication with the magnetic sensor can identify the turbine bucket as being one of deformed and non-deformed based on the magnetic field strength of the magnetized material.

Abstract: Methods of forming a desired geometry at a location on a superalloy part are disclosed. The method may include directing particles of a powder mixture including a low melt temperature superalloy powder and a high melt temperature superalloy powder to the location on the superalloy part at a velocity sufficient to cause the superalloy powders to deform and to form a mechanical bond but not a metallurgical bond to the superalloy part. The directing of particles continues until the desired geometry is formed. Heat is applied to the powder mixture on the repair location. The heat causes the low melt temperature superalloy powder to melt, creating the metallurgical bonding at the location. Another method uses the same directing to form a preform for repairing the location on the part. The low melt temperature superalloy powder melts at less than 1287° C., and the high melt temperature superalloy powder melts at greater than 1287° C.

Abstract: A method of repairing a superalloy component includes subjecting the superalloy component, including a repair area, to a phase agglomeration cycle, which includes stepped heating and controlled cooling of the component. The method further includes applying weld material to the repair area to create a weld surface; and covering the weld surface with brazing material. The component is then subjected to a braze cycle to produce a brazed component. The brazed component is cleaned, and the cleaned component is subjected to a restorative heat treatment to restore the microcrystalline structure and mechanical properties of the component.
