摘要： Provided is a copper-nickel alloy electroplating apparatus which is capable of stably forming a copper-nickel plated coating on a workpiece with a uniform composition and which enables a plating bath to be used for a long period. The present invention provides a copper-nickel alloy electroplating apparatus (1), comprising: a cathode chamber (4) in which a workpiece (5) is to be placed; an anode chamber (6); an anode (7) placed in the anode chamber; an electrically conductive diaphragm (14) placed to separate the cathode chamber and the anode chamber from each other; a cathode chamber oxidation-reduction potential adjusting tank (8) for adjusting the oxidation-reduction potential of a plating liquid in the cathode chamber; an anode chamber oxidation-reduction potential adjusting tank (10) for adjusting the oxidation-reduction potential of a plating liquid in the anode chamber; and a power supply unit (36) that provides an electric current to flow between the workpiece and the anode.

摘要： The purpose of the present invention is to provide an electrical Al plating bath that poses little danger of exploding or igniting as a result of contacting air or water, and contains no benzene, toluene, xylene, naphthalene, or 1,3,5-trimethylbenzene, which have detrimental effects to humans. The present invention provides an electrical aluminum or aluminum alloy fused salt plating bath that is obtained by heat treatment of an electrical aluminum or aluminum alloy fused salt plating bath containing (A) a halogenated aluminum as the primary component and (B) at least one other type of halide after adding (C) one, two or more reducible compounds selected from the group consisting of hydrides of elements in Group 1 Periods 2 through 6 of the Periodic Table of Elements and/or hydrides of Group 13 Periods 2 through 6 of the Periodic Table of Elements and amine borane compounds.
