Abstract: A braze system is disclosed, including a first surface, a second surface, a gap disposed between the first surface and the second surface, a capillary matrix disposed in the gap, and a braze material disposed in contact with the capillary matrix. The capillary matrix includes a matrix structure forming a plurality of capillaries. A brazed article is disclosed in which the braze material is disposed within the plurality of capillaries and contacts the first surface and the second surface. The braze material, the capillary matrix, the first surface, the second surface, and the gap form a brazed portion including less than about 20% voiding. A method for forming a brazed article includes disposing the capillary matrix into the gap, and infusing a braze material into the plurality of capillaries and in contact with the first surface and the second surface, forming the brazed portion.

Abstract: A method of brazing includes placing a non-foam matrix in a gap and applying a molten braze material to the gap such that the molten braze material flows into the gap and through the non-foam matrix by capillary action to fill the gap and cools to form a solid braze in the gap. A brazed article includes at least one component defining a gap, a non-foam matrix in the gap and a solid braze interspersed through the non-foam matrix. The non-foam matrix and the solid braze fill the gap.
