Insulation method and material for improving oxidation resistance of metal magnetic powder core |
| abstract |
The invention provides a preparation method of a soft magnetic composite material with strong oxidation resistance. The method comprises the following steps: iron-nickel magnetic powder or mixed metal magnetic powder of iron-nickel and iron-silicon-aluminum; mixing nano oxides in an organic solvent; The configuration is added to the metal magnetic powder, stirred, and the organic coating agent is added; or the organic coating agent is added to the solution and then poured into the metal magnetic powder, and stirred; the obtained metal magnetic powder is added to the phosphoric acid solution, and a mold release agent is added to the magnetic powder. And mix evenly to make magnetic powder to be formed; press molding and heat treatment to make semi-finished magnetic powder core. |
