FIELD: electricity.
SUBSTANCE: method to manufacture a composite soft magnetic material consists in mixing of a lubricant, for instance, zinc stearate, kenolyub, stearamide or other powder lubricants, with a powder based on iron in ball mills and other mixers, at the same time after mixing the composite material is placed into a rotary drum with pressure of 10-2-10-3 mm of mercury column, heated to the temperature of lubricant melting - 150-200°C, treatment is carried out to produce even distribution of the lubricant in the material for 15-30 minutes, at the same time lubricant content in the composite material makes from 0.01 to 0.1%.
EFFECT: reduced porosity of products after pressing, higher magnetic induction and magnetic permeability of items due to reduction of lubricant content in a composite soft magnetic material.
