    摘要: A process for electrolytic production of fine-grained, single-phase, metallic alloy powders, especially powders of intermetallic compounds as well as noble metal alloy powders, is described in which powdery metallic precipitates are galvanically produced on the cathode from an electrolytic precipitating bath known in the art, which contains in solution the metals to be precipitated, under electrolysis conditions causing a powder precipitation known in the art. For the production of alloy powders with defined properties, it is determined, first in preliminary tests by gradual increase of the cathode potential with otherwise constant process parameters, the minimum cathode potential at which single-phase alloy powders result and then the powder precipitation is potentiostatically performed in a cathode potential at or above the minimum for the single-phase alloy precipitation.
