The application research of Rare Earth additives in the metal electro-deposition technology

Rare Earth is a kind of limited resources, so extending the application field of Rare Earth is an effective way to protect the limited resources and improve their value. The main functions of Rare Earth compounds as additives in electro-deposition technology are introduced, for example, using them as exutory and conductor, what is more, the functions also including specific adsorption and nucleation of Rare Earth elements. It was introduced that the application research and development of Rare Earth elements as additives on zinc-plating, chromium-plating, nickel-plating, tin-plating, iron-plating and copper-plating. Rare Earth elements can greatly improve performance and quality of the cladding and plating solution, so the application of Rare Earth additives in the field of electro-deposition will have a good application prospect.
