A method for manufacturing bodies formed from insulated soft magnetic metal powder by forming an insulating film of an inorganic substance on the surface of particles of a soft magnetic metal powder, compacting and molding the powder, then carrying out a heat treatment to provide a body formed from insulated soft magnetic metal powder the method comprising: compacting and molding the powder; then magnetically annealing the powder at a high temperature above the Curie temperature for the soft magnetic metal powder and below the threshold temperature at which the insulating film is destroyed in a non-oxidizing atmosphere, such as a vacuum, inert gas,or the like; and then carrying out a further heat treatment at a temperature of from 400 deg C to 700 deg C in an oxidizing atmosphere, such as air, or the like.

La présente invention concerne un procédé de fabrication de corps formés à partir de poudre métallique à aimantation temporaire isolée par formation d~une pellicule isolante d~une substance inorganique sur la surface des particules d~une poudre métallique à aimantation temporaire, par compactage et moulage de la poudre, puis par application d~un traitement thermique pour créer un corps formé à partir de poudre métallique à aimantation temporaire isolée. Cedit procédé comprend : le compactage et le moulage de la poudre ; puis le recuit magnétique de la poudre à une température élevée supérieure à la température de Curie pour la poudre métallique à aimantation temporaire et inférieure au seuil de température auquel la pellicule isolante est détruite dans une atmosphère non-oxydante, telle qu~un vide, un gaz inerte ou similaire ; puis l~application d~un autre traitement thermique à une température comprise entre 400 °C et 700 °C dans une atmosphère oxydante, telle que l~air ou similaire.
