Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a rare earth yttrium-nickel-phosphorus 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 15 oxides of yttrium-series elements with atomic numbers from 57 to 71 in the periodic table of elements, and oxides of scandium (Sc) and yttrium (Y), which have similar chemical properties to yttrium-series 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, nickel-zinc alloy plating is widely used industrially...
