| Abstract: |
| Fe-based soft magnetic materials mainly include FeNi alloy, FeCo alloy and FeSi alloy. Due to their excellent soft magnetic properties such as high magnetization, high magnetic susceptibility and low coercivity, they are widely used in electronics, electrical, national defense fields. With the development of science and technology, electronic components are required to have smaller sizes and better performance, so the demand for thinning the soft magnetic materials is becoming increasingly urgent. From the basic principles of electrochemistry, this paper briefly analyzes and introduces the influence and control of various process parameters of the electrodeposition synthesis of Fe-based soft magnetic film materials based on the current research status. The first part of the paper mainly introduces the electrodeposition method. Electrodeposition refers to the process in which related ions in the solution are electrochemically reduced to metal atoms on the surface of the cathode under the action of an electric field and then enter the metal lattice. The general reaction conditions are normal temperature and pressure. Various methods of controlling the composition, morphology, thickness, and performance of the deposited layer by electrodeposition are introduced. The second part of the paper mainly introduces the current status of the electrodeposition process of Fe-based soft magnetic films. The research shows that the deposition current, the composition of the plating solution, the pH value of the plating solution, temperature, the deposition time, the external magnetic field and other factors will affect the composition and performance of the magnetic film. In addition, because the electrochemical preparation of FeSi alloys belongs to the composite electrodeposition technology, this paper introduces it separately. This part mainly introduces the dispersibility of silicon in FeSi alloy composite codeposition, and briefly summarizes the research status of FeSi alloy electrodeposition. The main purpose of this paper is to have a certain grasp of the current research of Fe-based soft magnetic materials, and to provide reference for future development. |
