Abstract

The invention discloses yttrium-nickel-iron alloy electroplate liquid and an electroplating method thereof. The yttrium-nickel-iron alloy electroplate liquid comprises 100 g / L-180 g / L of ferrous sulfate, 120 g / L-200 g / L of nickel sulfate, 15 g / L-30 g / L of sodium chloride, 10 g / L-20 g / L of sodium glycollate, 10 g / L-25 g / L of lactic acid, 30 g / L-45 g / L of complexing agents, 2 g / L-5 g / L of stabilizer, 0.1 g / L-0.3 g / L of primary brightener, 3 g / L-8 g / L of brightener and the balance deionized water. Rare earth metal yttrium is added to the yttrium-nickel-iron alloy electroplate liquid, so that the electroplate liquid is good in stability, high in electroplating efficiency, low in cost, safe and environmentally friendly. A plated layer obtained through electroplating is attractive in color and luster, good in smoothness and good in density and flexibility.

Description

technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a yttrium-nickel-iron alloy electroplating solution and an electroplating method thereof. Background technique [0002] With the continuous development of science and technology, the requirements for products are becoming more and more stringent, and the coating of a single element is difficult to meet the needs of electroplating products. Researchers are gradually turning their attention to alloy electroplating. [0003] The nickel-iron alloy coating has superior physical and chemical properties. Compared with the traditional nickel plating process, the nickel-iron alloy plating replaces part of the expensive metal nickel with cheap pure iron, so that harmful iron impurities become beneficial components in the coating, which not only reduces It not only reduces the cost of electroplating, but also reduces the disadvantages of pinholes and brittleness of the coat...
