The most important property of SMC materials, especially those used in a high-frequency range, is that the soft-magnetic powder particles are well insulated from each other. The Fe-Si-B powders were prepared by water-atomisation and were compared with some commercially available powders. The surfaces of microcrystalline powders were investigated using high-resolution Auger-electron spectroscopy (HRAES) and X-ray photoelectron spectroscopy (XPS). The electrical break-down voltages, permeability and electrical losses of SMC materials were measuredNa osnovi prahu Fe-Si-B smo razvili mehkomagnetne kompozitne materiale. Če so namenjeni za uporabo v visokofrekvenčnem področju, morajo imeti zelo dobro izolacijo med posameznimi delci-prahovi. Prahove Fe-Si-B smo pripravili po postopku vodne atomizacije in jih primerjali z nekaterimi komercialnimi. Površine mikrokristaliničnih prahov smo preiskali z visoko ločljivim Augerjevim elektronskim spektrometrom (HR AES) in z rentgenskim fotoelektronskim spektrometrom (XPS). Izmerili smo tudi nekatere električne lastnosti mehkomagnetnih kompozitov, kot so: električna prebojna napetost, permeabilnost in električne izgubeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
