Optimizing Properties of Additively Manufactured NiZnCu-Ferrite Soft Magnetic Composites

Team: Damini Frey

Program: Materials Science and Engineering

Soft magnetic composites (SMCs) are a type of magnetic material that have applications in electronic devices. Traditional manufacturing techniques are design restricting and unable to produce SMCs with complex geometries. Recently, additive manufacturing (AM) methods have been shown to overcome this problem. Laser Powder Bed Fusion (L-PBF) can be used to produce SMCs with higher permeability and greater flexibility in geometry than traditional manufacturing methods. Despite these advantages, SMCs manufactured by AM methods still don’t exhibit optimal properties, such as density, eddy current control, and coercivity, for their intended use in electronic devices. This project compares magnetic data collected through Magneto-Optic Kerr Effect (MOKE) magnetometer with microstructure data collected using Electron Backscatter Diffraction (EBSD) through a Scanning Electron Microscope (SEM) to determine the optimal laser processing parameters.
