Description

technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a samarium-tin-copper 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. ...
