PURPOSE: To obtain Fe-Cu-Ni compound powder for powder metallurgy capable of obtaining a homogeneous sintered body having high density and high strength by applying Ni electroless plating to the surface of iron powder and thereafter applying Cu-Ni electroless plating thereto to regulate its compsn. into a specified one. ;CONSTITUTION: The Fe-Cu-Ni compound powder for powder metallurgy is one which the surface of the iron powder is applied with the Cu-Ni plated layer, and its compsn. is constituted of, by weight, 0.1 to 10% Cu and 1 to 20% Ni, and the balance Fe with inevitable impurities. By subjecting it to compacting and sintering, a sintered body having high density and dimensional stability as well as high strength can be obtd. This compound powder can inexpensively and efficiently be manufactured by previously applying the Ni electroless plating to the surface of the iron powder and thereafter applying the Cu-Ni electroless plating thereto to uniformly stick the Cu-Ni alloy.;COPYRIGHT: (C)1994,JPO&Japio
