| Abstract |
|
Powder injection moulding is an enabling technology for the production of soft ferromagnetic components, which bring solutions and open the way for new applications. In this work, square toroid parts have been injection moulded for three typical soft magnetic alloy compositions. Fe2.7Si, Fe50Ni and Fe50Co feedstocks were produced by mixing elemental powders and a multicomponent binder. The green parts were first solvent debinded in a heptane bath. Then, thermal debinding under nitrogen atmosphere and sintering under hydrogen atmosphere were performed in a single step in a retort furnace. The sintered parts were characterized by measurements of B-H hysteresis cycles and optical metallography. The results were compared with literature values obtained from powder metallurgy processes. |
