Patent number: 11753724Abstract: 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.Type: GrantFiled: August 1, 2022Date of Patent: September 12, 2023Assignee: General Electric CompanyInventors: Yan Cui, Matthew Joseph Laylock, Brian Lee Tollison
