Abstract

The invention discloses a rare-earth-yttrium-nickel-zinc-alloy electroplating solution and a preparation method thereof. The rare-earth-yttrium-nickel-zinc-alloy electroplating solution comprises 120-200 g / L of nickel sulfate, 15-30 g / L of zinc sulfate, 0.05-1 g / L of yttria, 10-20 g / L of sodium glycolate, 10-25 g / L of citric acid, 2-5 g / L of a stabilizing agent, and 3-8 g / L of a brightener. The are-earth-yttrium-nickel-zinc-alloy electroplating solution has good stability and high cathode current efficiency. The obtained electroplated layer is uniform in dispersion, beautiful in color, and good in compactness and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a rare earth yttrium-nickel-zinc alloy electroplating solution and a preparation 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, the plating solution of nickel-zinc alloy mainly adopts a...
