Original Abstract Submitted

A metal coupon for repairing a component includes an additively manufactured (AM) metal member having at least two porous regions and a braze material infiltration barrier positioned between the at least two porous regions. The braze material infiltration barrier has a lower porosity than the at least two porous regions. A component using the metal coupon may also include a braze material coupling the metal coupon in a coupon opening in the body. The braze material infiltrates at least one of the two porous regions, and the braze material infiltration barrier separates the braze material in the at least one of the two porous regions from at least one other of the at least two porous regions. Different braze materials may be used in each porous region.
