Abstract
(EN)
A method for plating rare earth metal is provided. The method for plating rare earth metal may comprise the steps of: preparing a base metal comprising a calcium (Ca) compound and a rare earth metal compound; preparing a plating source including a calcium reactant, a first metal precursor comprising a first metal, and a second metal precursor comprising a second metal; and providing the plating source to the base metal so that while the calcium included in the calcium compound reacts with the calcium reactant, an alloy of the first metal and the second metal is plated on the surface of the rare earth metal compound.
(FR)
L'invention concerne un procédé de placage de métal de terres rares. Le procédé de placage de métal de terres rares peut comprendre les étapes suivantes : préparation d'un métal de base comprenant un composé de calcium (Ca) et un composé de métal de terres rares ; préparation d'une source de placage comprenant un réactif de calcium, un premier précurseur de métal comprenant un premier métal et un deuxième précurseur de métal comprenant un deuxième métal ; et fourniture de la source de placage au métal de base de sorte que pendant que le calcium inclus dans le composé de calcium réagit avec le réactif de calcium, un alliage du premier métal et du deuxième métal est plaqué sur la surface du composé de métal de terres rares.
