Abstract
A method of repairing an article having a surface and a defect is provided. The method includes forming a groove in the article at the defect and the top surface. The method further includes providing a superalloy powder to the groove such that the superalloy powder at least partially fills the defect and the groove. The method further includes providing a braze powder on the superalloy powder at the groove and the surface. The method further includes heating the article such that the braze powder becomes a liquified braze material and infiltrates the groove and the defect.
Claims20
A method of repairing an article having a surface and a defect, the method comprising:
- machining a groove in the article at the defect and the surface, wherein the groove defines a first depth and the defect defines a second depth, and wherein the first depth is less than the second depth;
- providing a superalloy powder to the groove such that the superalloy powder at least partially fills the defect and the groove;
- providing a braze powder on the superalloy powder at the groove and the surface;
- and
- heating the article such that the braze powder becomes a liquified braze material and infiltrates the groove and the defect.
A method of repairing a turbomachine component having a surface and a defect, the method comprising:
- machining a groove in the turbomachine component at the defect and the surface, wherein the groove defines a first depth and the defect defines a second depth, and wherein the first depth is less than the second depth;
- providing a superalloy powder to the groove such that the superalloy powder at least partially fills the defect and the groove;
- providing a braze powder on the superalloy powder at the groove and the surface;
- and
- heating the turbomachine component to a temperature above a braze powder melting point and below a superalloy powder melting point, whereby the braze powder becomes a liquified braze material and infiltrates the superalloy powder in the groove and the defect.
