Abstract (en)
[origin: WO2016162383A1] The invention relates to a method (100) for producing a soft-magnetic body (10), comprising the following steps: a) providing a soft-magnetic powder (20) with powder particles (21) that consist of a soft-magnetic material (22), b) coating the powder particles (21)with an insulating coating material (31), the sintering temperature of the coating material (31) being lower than the sintering temperature of the soft-magnetic material (22), and c) heat-treating the coating material (31) in such a way that during the heat treatment a sintering and/or melting of the powder particles (21) is avoided.
