FeSiAl/FeCuNbSiB magnetic core prepared by powder extrusion
Source abstract
Abstract
FeSiAl/FeCuNbSiB nanocrystalline powder core was prepared by powder press extrusion,and its magnetic properties were studied at different amounts of FeSiAl composite powder and with glue powder.The results show that a glue binding formulation of 1% octadecanoic acid,20% polypropylene and 79% paraffin wax,glue/powder ratio 10∶1(weight) FeSiAl/FeCuNbSiB nanocrystalline magnetic core,with a magnetic core density 4.69g/cm3.Composite of FeCuNbSiB nanocrystalline powder(300mesh) and 200mesh powder FeSiAl compound,at ratio of FeSiAl powder 200mesh 30wt%+300mesh 70wt% FeCuNbSiB,powder core/glue at 10∶1(wt),44℃×0.5h petroleum ether defatted,heat treatment temperature of 160℃×1h,the magnetic core achieves the best soft magnetic properties,f is 600kHz,μe reaches 16.48,Q equals 57.5.Frequency and temperature changes on the magnetic powder core effective magnetic permeability effect is small.
