Abstract

NdFeB magnets display excellent magnetic properties, but severe corrosion often restricts their applications. Developing surface protection coatings is essential to mitigate this issue. In this study, Ti₃C₂T_x-Ni nanocomposite coatings were successfully deposited on NdFeB magnets through electrostatic self-assembly and pulsed-current electrodeposition. The results indicate that ammonia-modulated Ti₃C₂T_x-Ni nanocomposite coatings display excellent surface flatness and improved anti-wear and anti-corrosion properties. Microstructure analyses and density functional theory calculations reveal that NH₃·H₂O effectively modulates Ni²⁺ ion adsorption on Ti₃C₂T_x, alleviating Ti₃C₂T_x aggregation in the electrolyte. Further, the energy barrier for Cl^- penetration into Ti₃C₂T_x is higher than that for Ni, providing significant support for enhancing the corrosion resistance of the Ti₃C₂T_x-Ni coating. This work presents a novel strategy for providing improved protection to NdFeB magnets using Ti₃C₂T_x-Ni nanocomposite coatings, thereby expanding their potential applications in harsh environments.
