The distribution of contact points formed between a flat solid surface and a metallic gauze has been examined, and the thermal resistances of contacts with gauze inserts have been measured. The resistance of a steel-to-steel contact in an ambient air environment was increased by the insertion at the interface of a gauze made from soft, high-conductivity metallic wires, but similar inserts led to a decrease of the overall resistance of the assembly in a high vacuum.
