Abstract
(EN)
A preparation method for a metal matrix composite wire and a power inductor. The preparation method for the metal matrix composite wire comprises the steps of: 1) preparing a metal core; 2) formulating a glass resin mixture: premixing borosilicate glass powders and a solvent and uniformly stirring same, and then adding a dispersing agent and a resin with a decomposition temperature of 300-500 °C, uniformly stirring and mixing same; 3) dissolving a self-adhesive resin into a solvent to formulate a resin solution; 4) uniformly coating the glass resin mixture on the surface of the metal core, then coating the self-adhesive resin solution on the surface of the glass resin mixture, and drying at a temperature of 80-150 °C; and 5) repeating the step 4) until the coating thickness reaches 2-10 μm. A final power inductor is prepared by using the above-mentioned composite wire, pressing it together with magnetic powders to form an inductor; performing sintering at a temperature of 600-900 °C; and grinding and polishing the composite wire extending out of the two ends of the magnetic body of the inductor.

La présente invention concerne un procédé de préparation d'un fil composite à matrice métallique et d'une inductance de puissance. Le procédé de préparation du fil composite à matrice métallique comprend les étapes suivantes : 1) préparation d'une âme métallique ; 2) formulation d'un mélange verre/résine : prémélange de poudres de verre borosilicaté et d'un solvant et agitation uniforme de ces derniers, puis ajout d'un agent dispersant et d'une résine présentant une température de décomposition de 300 à 500 °C, agitation uniforme et mélange de ces derniers ; 3) dissolution d'une résine auto-adhésive dans un solvant en vue de formuler une solution de résine ; 4) application d'un revêtement uniforme du mélange verre/résine sur la surface de l'âme métallique, puis application d'un revêtement de la solution de résine auto-adhésive sur la surface du mélange verre/résine, et séchage à une température de 80 à 150 °C ; et 5) répétition de l'étape 4) jusqu'à ce que l'épaisseur du revêtement atteigne 2 à 10 µm. Une inductance de puissance finale est préparée à l'aide du fil composite susmentionné, par compression de ce dernier avec des poudres magnétiques en vue de former une inductance ; réalisation d'un frittage à une température de 600 à 900 °C ; et meulage et polissage du fil composite s'étendant hors des deux extrémités du corps magnétique de l'inductance.
