Abstract

The invention discloses copper-zinc alloy electroplate liquid and an electroplating method thereof. The copper-zinc alloy electroplate liquid comprises 40-60 g / L of copper sulfate, 6-10 g / L of cupric pyrophosphate, 6-10 g / L of diammine dichloropalladium, 20-40 g / L of zinc sulfate, 20-30 g / L of potassium citrate, 5-10 g / L of amino acid, 4-8 g / L of saccharin and 10-15 g / L of sodium acetate. An electroplating layer obtained in an electroplating manner through the copper-zinc alloy electroplate liquid is free of cracks, and corrosion resistance and abrasion resistance are good.

Description

technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a copper-zinc 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 plating process is widely used in all aspects of the electroplating industry, and is used for surface treatment of metal devices for anti-corrosion and decoration purposes. However, due to the non-renewable nature of nickel resources, with the continuous increase of nickel consumption, the supply has been seriously insufficient, causing the price to soar, and the nickel plating cost of various electroplating enterprises remains high. Electro...
