Metal coupon with braze reservoir for component, component with same and related method

A metal coupon for inserting in a component, the metal coupon comprising:

• an additively manufactured (AM) metal member including a braze reservoir, the braze reservoir including:
• a first cavity in the AM metal member;
• a first conduit fluidly coupling the first cavity to a braze region;
• and
• a blocking member blocking fluid communication through the first conduit between the first cavity and the braze region;
• a first braze material in the first cavity;
• a seal member sealing the first cavity from an exterior of the AM metal member;
• and
• a second conduit fluidly coupling the first cavity to an exterior surface of the AM metal member, wherein the seal member seals the second conduit from the exterior surface of the AM metal member.

An additively manufactured (AM) component, comprising:

• a body including a braze reservoir, the braze reservoir including:
• a first cavity defined in the body;
• a first braze material in the first cavity;
• a seal member sealing the first cavity from an exterior of the body;
• a first conduit defined in the body and fluidly coupling the first cavity to a braze region;
• a second conduit fluidly coupling the first cavity to the exterior surface of the body, wherein the seal member seals the second conduit from the exterior surface of the body;
• and
• a blocking member extending across the first conduit to block fluid communication between the first cavity and the braze region prior to exposure of the blocking member to a predetermined temperature exceeding a melting temperature of the first braze material.

An additively manufactured (AM) component, comprising:

• a body including a braze reservoir, the braze reservoir including:
• a first cavity defined in the body;
• a first braze material in the first cavity;
• a seal member sealing the first cavity from an exterior of the body;
• a first conduit defined in the body and fluidly coupling the first cavity to a braze region;
• and
• a blocking member extending across the first conduit to block fluid communication between the first cavity and the braze region prior to exposure of the blocking member to a predetermined temperature exceeding a melting temperature of the first braze material, wherein in response to the body exceeding the predetermined temperature, the first cavity is an at least partially open space.
