Abstract

The invention discloses samarium-zinc-iron alloy electroplating liquid and an electroplating method thereof. The samarium-zinc-iron alloy electroplating liquid comprises the following components: 80-120 g / L of zinc sulfate, 30-50 g / L of ferrous sulfate, 0.05-0.3 g / L of samarium oxide, 10-15 g / L of sodium chloride, 5-10 g / L of glycolic acid sodium, 10-20 g / L of potassium citrate, 2-5 g / L of ascorbic acid, 0.1-0.3 g / L of benzene sulfinic acid sodium salt and 1-1.5 g / L of alkalified tetraisopropylamine. The rare earth metal samarium is added in the samarium-zinc-iron alloy electroplating liquid, so that the electroplating liquid is excellent in stability, high in electroplating efficiency, safe and environment-friendly; and a samarium-zinc-iron alloy plating layer obtained through electroplating is excellent in corrosion resistance and levelness.

Description

technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a samarium-zinc-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] Zinc-iron alloy coating has superior physical and chemical properties. Compared with traditional galvanizing process, zinc-iron alloy electroplating uses cheap pure iron to replace some expensive metal zinc, 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 coating. In recent year...
