Investigation of Electric Characteristics of Contact Assemblages with a Powder Damping Interlayer

Abstract

In our work there were investigated thermal electrophysical characteristics of coaxial contact assemblages, made of a steel current carrying rod, steel or cermet sleeve and filled with an iron or nichrome powder. As a result of heating up to 950 ºС the iron powder was shown to be sintered and develop a highly conductive and damping medium that can be used for making contact junctions of materials having very different linear expansion coefficients.
