A nickel-cobalt alloy electroplating solution and an electroplating method are disclosed. The electroplating solution comprises 260-300 g / L of nickel sulfate, 40-60 g / L of nickel chloride, 25-40 g / L of boric acid, 5-15 g / L of cobaltous sulfate, 0.5-2 mL / L of a brightener and 0.05-0.2 g / L of an emulsifier, wherein the brightener is a mixture of a BE nickel plating brightener, propynol ethoxylate, propargyl sulfonate and saccharin. Divalent cobalt ions and divalent nickel ions in the electroplating solution are co-deposited on the surface of a workpiece to be plated in a cathode. The cobalt element introduced into a plating reduces porosity of the plating and enhances hardness, wear resistance and brightness of the plating.
Description
technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a nickel-cobalt alloy electroplating solution. Background technique [0002] Electroplating is a metal electrodeposition method, which refers to the process of reducing the metal ions in the electrolyte under the action of direct current and depositing them on the surface of the workpiece to form a metal coating with certain properties. Compared with other surface treatment technologies such as coating and vapor deposition, electroplating has the advantages of fast deposition speed, uniform coating thickness, and thin coating, so it has become a common way of metal corrosion protection today. [0003] Nickel has excellent physical, chemical and mechanical properties. Nickel-coated film materials prepared by electroplating have been widely used in ten lamps, vehicles, batteries, printing and other industrial fields, playing an important role in the protection and ...
