摘要: The present invention concerns a powder magnetic core for operating at high frequencies obtained by pressure forming an iron-based magnetic powder covered with an insulation film, and a specific resistance less than 1000, preferably less than 2000 and most preferably less than 3000 µm, a saturation magnetic flux density B above 1.5, preferably above 1.7 and most preferably above 1.9 (T). The invention also concerns the preparation of such cores as well as a powder which is suitable for the preparation.

摘要: The present invention concerns a process for the manufacture of soft magnetic composite components comprising the steps of : die compacting a powder composition comprising a mixture of soft magnetic, iron or iron-based powder, the core particles of which are surrounded by an electrically insulating, inorganic coating, and an organic lubricant in an amount of 0.05 to 1.5 % by weight of the composition, said organic lubricant being free from metal and having a temperature of vaporisation less than the decomposition temperature of the coating; ejecting the compacted body from the die; heating the compacted body in a non reducing atmosphere to a temperature above the vaporisation temperature of the lubricant and below the decomposition temperature of the inorganic coating for removing the lubricant from the compacted body, and subjecting the obtained body to heat treatment at a temperature between 3000C and 600°C in water vapour. The invention also concerns soft magnetic composite components having a transverse rupture strength of at least 100 MPa, a permeability of at least 700 and a core loss at 1 Tesla and 400 Hz of at most 70W/kg.
