Abstract:
1. A method for treating a surface of a laser sintered material, the method comprising the steps of: forming a substrate by a laser sintering process so as to comprise sintered powder particles and contain porosity, said substrate having an internal surface that contains crevices and defines an internal passage of said component and an oppositely-disposed second surface; applying a braze material to a portion but not all of said internal surface of said substrate; and heating said braze material such that said braze material melts and wets said internal surface and flows by capillary forces created by said crevices to become evenly distributed on said internal surface and form a cladding layer that completely fills said crevices in said internal surface and causes said internal surface to be smoother and protected relative to said second surface.
