Abstract

The invention discloses a rare-earth-cerium-copper-zinc-alloy electroplating solution and an electroplating method thereof. The rare-earth-cerium-copper-zinc-alloy electroplating solution comprises 10-80 g / L of copper sulfate, 4-60 g / L of zinc sulfate, 0.1-1 g / L of cerium dioxide, 4-40 g / L of amino acid, 100-200 g / L of sodium pyrophosphate, and 3-8 g / L of a brightener. The rare-earth-cerium-copper-zinc-alloy electroplating solution has good stability. An obtained electroplated layer has a beautiful color, compactness, and excellent corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a rare earth cerium-copper-zinc alloy electroplating solution and an electroplating method thereof. Background technique [0002] Rare earths are known as "industrial vitamins". Now it has become an extremely important strategic resource. Rare earth element oxides refer to oxides of 15 lanthanide elements with atomic numbers from 57 to 71 in the periodic table of elements, and oxides of scandium (Sc) and yttrium (Y), which are chemically similar to lanthanide elements, a total of 17 elements. . Rare earth elements have been widely used in petroleum, chemical industry, metallurgy, textile, ceramics, glass, permanent magnet materials and other fields. With the advancement of science and technology and continuous breakthroughs in application technology, the value of rare earth oxides will increase. [0003] At present, copper-zinc alloy plating is widely used industrially ...
