Abstract Scope |
Additively manufactured soft magnetic parts enable enhance magnetic performance with a complex design. Binder jetting followed by sintering results in a uniform grain size distribution, enabling the tailoring of magnetic performance compared to fusion-based additive manufacturing. In this study, binder jet additive manufacturing of Fe-50Ni soft magnetic permalloy, a widely utilized soft magnetic alloy known for its high permeability and low coercivity, is employed to investigate the effects of fine (d_50=14 μm) and coarse (d_50=31 μm) powder sizes, as well as sintering conditions, on the density and magnetic characteristics of toroidal core inductors. Powder samples were additionally sintered in the cylindrical alumina to distinguish the impact of binder on sintering. Cubes and toroidal parts were printed, and sintered in atmospheric and vacuum furnaces. Density measurements were conducted, and the BH curves along with the core loss behavior of the specimens were analyzed at 5 Hz, 50 Hz, and 1000 Hz. |
