Patent number: 11919080Abstract: The successful fabrication of alloy foam (or porous alloy) is very rare, despite their potentially better properties and wider applicability than pure metallic foams. The processing of three-dimensional copper-nickel alloy foams is achieved through a strategic solid-solution alloying method based on oxide powder reduction or sintering processes, or both. Solid-solution alloy foams with five different compositions are successfully created, resulting in open-pore structures with varied porosity. The corrosion resistance of the synthesized copper-nickel alloy foams is superior to those of the pure copper and nickel foams.Type: GrantFiled: March 11, 2019Date of Patent: March 5, 2024Assignee: CellMo Materials Innovation, Inc.Inventors: Kicheol Hong, Hyeji Park, Sukyung Lee, Youngseok Song, Gigap Han, Kyungju Nam, Heeman Choe
