Samarium alloy is considered to be a potential function material, which has its changeable electrovalence character, is widely used as permanent-magnetic, hydrogen-storage, luminescent and aerospace materials. In this paper, the advantages and disadvantages of method, which were used to prepared Sm alloy, were compared. In contrast, the molten salt electrolysis has the advantages of cleaner products, inexpensive, and continuous production, becomes a focus in current research. The research progress and existing problems of Sm-Al, Sm-Cu, Sm-Co, Sm-Ni and Sm-Fe alloys prepared by molten salt electrolysis were emphatically described, and the electrochemical behaviors of Sm3+ and deposition process of Sm alloy were introduced. The direction of industrialization development was also put forward.
