High-performance rare earth magnets are critical components for electric vehicles, wind turbines, and automatization. This project investigates fluoride- and hydride-assisted grain boundary modification of sintered Nd–Fe–B magnets using Electrophoretic Deposition (EPD) followed by controlled heat treatments.

The primary focus is to study the influence of EPD-assisted surface treatments on the magnetic properties, including coercivity (Hc), remanence (Br), maximum energy product ((BH)max), and demagnetization curve squareness. Different fluoride and hydride compounds will be applied and their effect on magnetic performance will be systematically evaluated. In a second step, the impact of these treatments on electrical resistivity and corrosion behaviour will be investigated using standard electrochemical methods. Microstructural and phase characterization will be carried out to correlate grain boundary modification with functional properties.

The project can be conducted either as an Advanced Research Lab (ARL) or a Master’s thesis, depending on scope and duration.
