摘　　要：综述了水溶液中电沉积稀土合金膜的结构与性能的研究现状。其中结构包括显微结构、非晶形成规律、晶化动力学 ;性能涉及磁性、析氢电催化行为、耐腐蚀性、力学性能及光学性能。水溶液中电沉积稀土合金膜在一定的制备条件下具有非晶态结构 ,由于其优异的磁学、析氢电催化、耐腐蚀、力学及光吸收性能 ,已经应用于镀覆大的非平面电子装置、磁泡记忆元件、高温超导薄膜、磁光记录材料、电极材料、发光材料、储氢材料以及表面工程技术等领域 ,同时对水溶液中电沉积稀土合金膜的研究进行了展望。A review was given about the current state of the study on the structures and properties of rare earth alloy coatings electrodeposited from aqueous solutions, and the perspectives for their development were proposed. Thus the microstructure, amorphous phase forming rules, crystallization dynamics, magnetic performance, electrocatalysis for hydrogen evolution, corrosion resistance, and mechanical and optical properties of the electrodeposited rare earth alloy coatings wear summarized. It was pointed out that the rare earth alloy films electrodeposited under specific conditions in aqueous solutions had amorphous structure and excellent magnetic behavior, electrocatalytic activity for hydrogen evolution, corrosion resistance, mechanical strength, and optical absorption properties. This accounted for the wide application of the electrodeposited rare earth alloy coatings in non plane electron devices with large coatings, magnetic bubble memory components, high temperature super conductive films, magneto optical recording materials, electrode materials, luminescent materials, laser materials, hydrogen storage materials, and surface engineering and technology fields.
