Resumo

The work is devoted to the study of the magnetic hysteresis properties of ring-shaped magnetic cores made by selective laser melting (SLM) from iron powder. The dependence of the magnetic properties of the obtained samples on the parameters of additive manufacturing (speed and direction of the laser beam) and on subsequent heat treatment was investigated. It was found that reducing the speed of the laser beam spot movement along the build surface, selecting the direction of the laser beam spot movement along the axis perpendicular to the squeegee, and performing heat treatment leads to an increase in magnetic induction and magnetic permeability and a decrease in specific magnetic losses. This is due to the fact that during annealing, internal mechanical stresses are removed, the gradient of which hinders the movement of domain
boundaries during remagnetization. A comparison of the magnetic properties of printed samples and samples made by pressing from the same powder was carried out. It was shown that the pressed samples are inferior to the samples made by SLM in terms of magnetic induction and permeability.
