ABSTRACT:
Methods for producing alloy metal powders by electrodeposition are disclosed. Compositions comprising a core surrounded by at least one discrete, substantially laminar layer of a metal different from the core are formed by electro-depositing the different metal onto a core metal powder cathode. The electro-deposition may be repeated to provide successive laminar layers of different metals. By the methods disclosed herein alloy powders of controlled composition may be readily generated. Among the advantages of these processes are increased rate of subsequent sintering and decreased loss of the core metal through oxidation or evaporation.
