Title: Innovations of Kyungju Nam in Aluminum and Copper-Nickel Alloy Foams
Introduction
Kyungju Nam is a notable inventor based in Seoul, South Korea. He has made significant contributions to the field of materials science, particularly in the development of advanced foams. With a total of 3 patents, his work focuses on innovative methods for creating aluminum nitride and copper-nickel alloy foams.
Latest Patents
One of his latest patents is a method of making aluminum nitride foam. This porous aluminum nitride (AlN) offers a greater surface area and higher permeability, making it ideal for advanced functional applications. The challenge in manufacturing porous aluminum nitride lies in its high melting point, approximately 2200 degrees Celsius. However, Nam's new processing method synthesizes porous aluminum nitride through a complete transformation from porous aluminum, utilizing a remarkably low nitriding or sintering temperature. The resulting porous aluminum nitride foam has various applications, including filters, separators, heat sinks, ballistic armor, electronic packaging, light- and field-emission devices, and highly wear-resistant composites when infiltrated with metals such as aluminum, titanium, or copper.
Another significant patent by Nam is the method of making copper-nickel alloy foams. The successful fabrication of alloy foam is rare, despite its potentially superior properties compared to pure metallic foams. Nam's innovative approach involves a strategic solid-solution alloying method based on oxide powder reduction or sintering processes. He successfully created solid-solution alloy foams with five different compositions, resulting in open-pore structures with varied porosity. Notably, the corrosion resistance of these synthesized copper-nickel alloy foams surpasses that of pure copper and nickel foams.
