Abstract
An additive manufactured (AM) metal coupon for a turbomachine component is provided. The component includes an airfoil body having a pressure side, a suction side, a trailing edge, and a coupon opening. The AM metal coupon has an AM metal member with at least one slanted coupon side wall at an angle of less than 90° with an exterior surface of the AM metal member. The AM metal member also has a first porous region having a first porosity and a second porous region having a second porosity different than the first porosity. A braze material couples the AM metal coupon in the coupon opening in the airfoil body and infiltrates into at least one of the first porous region based at least on a characteristic of the first porosity and the second porous region based at least on a characteristic of the second porosity.
