<p>14AbstractMETHOD FOR THE PRODUCTION OF POWDER COMPOSITE CORES AND POWDER COMPOSITE COREA powder composite core is to be particularly dense and strong while being produced from soft magnetic alloys. In particular, the expansion of the heat-treated core is to be avoided. To produce this core, a strip of a soft magnetic alloy is first comminuted to form particles. The particles are mixed with a first binder having a curing temperature Ti,cure and a decomposition temperature Ti,ie.pose and a second binder having a curing temperature Tzar, and a decomposition temperature T24,.pose, wherein Ti,c„re < T2,.e TLiecompose < T2,iccompose. The mix is pressed to produce a magnet core while the first binder is cured. The magnet core is then subjected to a heat treatment accompanied by the curing of the second binder at a heat treatment temperature TAnneal> T2,cure.</p> |
