VERFAHREN ZUR HERSTELLUNG VON ELEKTRODEN DURCH ZERSTÄUBEN VON METALLSCHMELZEN MIT GLAS

摘要

A method of forming an electrode is characterized in that the method comprising forming a porous coating of an alloy by gas atomisation on a substrate. The porosity of the coating is provided by controlling one or more conditions selected from the group consisting of the height and duration of deposition of the spray onto the substrate, the rate deposition, the speed of the atomized particles impacting on the substrate size distribution of the spray droplets, the temperature above melting, the substrate temperature, the substrate thermal conductivity, the conductivity of the gas, and the temperature of the gas.
