Using reduced iron powder as raw material, Copper coated iron powder (CCIP) is prepared by electroless alkaline-based plating. We discuss the impacts of reductant concentration, plating solution temperature and main salt concentration on the properties of CCIP. Surface morphology and composition are studied by using scanning electron microscopy ...
