Porous metal coupon with thermal transfer structure for component and related component

Abstract

A component includes a body and an additively manufactured (AM) metal coupon that includes a primary member having a member porosity between 2% to 50% open space volume to total volume of the primary member. The primary member includes a first portion and a second portion distanced from the first portion by a gap. At least one thermal transfer structure, such as pin(s) and/or fin(s), extends between the first and second portions across the gap. A braze material couples the AM metal coupon in a coupon opening in the body, and infiltrates into the primary member based at least on a characteristic of the member porosity. The braze material may also infiltrate the thermal transfer structure(s), which may have the same or different porosity from the primary member. The thermal transfer structure(s) exhibit enhanced heat rejection, reduce weight of the component, and may improve component vibratory response.
