Abstract

To provide a high-nickel plating bath which is weakly acidic and can stably form a plating film having a nickel content of 11 to 19% (preferably 12 to 18%) even at a current density of 3A / dm2 or more. An acidic zinc-nickel alloy electroplating solution which contains an amine compound represented by the formula H2N-R1-R2 {wherein: R1 is [(CH2)M-NH]L or (CH2)N; R2 is H, NH2 or R3; R3 is an alkanol or alkoxyl group having 1, 2, 3, 4 or 5 carbon atoms; L is 2, 3, 4 or 5; M is 2, 3, 4 or 5; and N is 3, 4 or 5}.

Description

technical field [0001] The present invention relates to a zinc-nickel alloy plating solution and a plating method using the same. More specifically, it relates to an acidic zinc-nickel alloy plating solution and an electroplating method using the same. Background technique [0002] Steel and the like of automobile parts, building materials, and the like can be exemplified as one of the metals that are prone to rust. Conventionally, galvanizing and zinc-based alloy plating have been widely used as anticorrosion methods for such metals that are prone to rust. In particular, among zinc-plated alloys, zinc-nickel alloys are being widely used in automobile parts and the like because of their excellent corrosion resistance. As one of the specific methods of this zinc-nickel alloy plating, it can be deposited at the cathode by direct current electrolysis of a plating solution in which a compound of zinc and nickel is dissolved in a weakly acidic or alkaline aqueous solution.
