Disclosed are a Fe-Ni-P-RE multicomponent alloy plating layer, and electrodeposition preparation method and application thereof. An alloy plating layer obtained via electrodeposition contains elements of Fe, Ni, P and RE, the mass percentage of Fe being 20%-65%, the mass percentage of Ni being 25%-70%, the combined mass percentage of Fe and Ni being 65%-90%, the mass percentage of RE being 2%-25%, and the balance being P. The plating solution mainly contains the following components: ferrous salt, nickel salt, NaH2PO2, RECl3, H3BO3 and Na3C6H5O7. A multicomponent alloy plating layer of different components can be obtained by adjusting the main salt and complexing agent in the plating solution and by adjusting the process. The present invention realizes controllable adjustment to the components of the obtained plating layer while saving costs, and further improves indexes such as the thermal expansion coefficient, electrical property, magnetic property, etc., and is very suitable for applications in the field of micro-electronics. |
