Annealable insulated metal-based powder particles and methods of preparing and using the same are provided. The insulated metal-based powder particles are formed from metal-based core particles that are coated with an annnealable insulating material. The annealable insulating material has at least one inorganic compound and at least one organic polymeric resin. The inorganic compound in the insulating material forms a nonporous insulating layer surrounding the metal-based core particles upon heating. The organic poylmeric resin preferably aids in dispersing or binding the inorganic compound to the metal-based core particles prior to annealing. The insulated metal-based powder particles produced can be formed into core components that can be annealed to improve the magnetic peformance of the core component. The core components produced are particularly useful under AC operating conditions of 500 Hz or lower.

L'invention concerne des particules de poudre à base métallique isolées pouvant être recuites, ainsi que des procédés permettant de les préparer et de les utiliser. Les particules de poudre à base métallique isolées sont formées à partir de particules noyau à base métallique revêtues d'un matériau isolant pouvant être recuit. Ledit matériau renferme au moins un composé inorganique et au moins une résine polymère organique. Le composé inorganique dans le matériau isolant forme une couche isolante non poreuse enveloppant les particules noyau lors du chauffage. De préférence, la résine polymère aide à disperser le composé inorganique ou à le lier aux particules noyau à base métallique avant le recuit. Avec les particules de poudre à base métallique isolées produites, on peut créer des éléments noyau que l'on peut recuire pour améliorer leur performance magnétique. Lesdits éléments sont particulièrement utiles dans des conditions de fonctionnement en courant alternatif de 500 Hz ou inférieur.
