Multilayered nano-foils for low-temperature metal-ceramic joining

Abstract

Over almost two decades metal-ceramic fusing has been the essential step in obtaining materials which benefit from both ceramic and metal materials, i.e. where the combined properties of the metal and ceramic layers are desirable. Soldering and active metal brazing are the most effective when considering fusing methods. This paper presents a low-temperature process for soldering and brazing ceramics to metals, which is based on the use of reactive multilayer foils as a local heat source. The reactive foils range in thickness from 40 μm to less than 100 μm and contain many nanoscale layers and/or domains that alternate between materials with high mixing heat. .
