Abstract
A metal coupon for repairing a component includes an additively manufactured (AM) metal member having a low porosity region in an interior of the AM metal member, and a porous region around the low porosity region. The low porosity region may have a porosity in a range of 0% to 5%, so is solid or nearly solid. The porous metal coupon with low porosity region allows braze material to be directed based on characteristics of the porous region.
Claims10
A method of repairing a component, the method comprising:
- additively manufacturing a metal coupon having a low porosity region in an interior thereof and a porous region that completely surrounds the low porosity region, wherein the low porosity region has a porosity lower than the porous region;
- positioning the metal coupon in a coupon opening in a body of the component;
- and
- infiltrating the metal coupon with a braze material to couple the metal coupon in the coupon opening to the body with the low porosity region therein, the braze material infiltrated into the porous region.
