| titleOfInvention | A kind of insulation coating method of soft magnetic alloy powder |
| abstract | The invention discloses an insulation coating method for soft magnetic alloy powder, comprising: step S1, powder mixing: doping soft magnetic ferrite fine powder into soft magnetic alloy powder, and fully and uniformly mixing; step S2, powder heat treatment : The mixed powder is heat-treated to obtain the first mixed powder; step S3, passivation treatment: the first mixed powder is mixed with the passivating agent solution, stirred and fully reacted, and the second mixed powder is obtained after cleaning and drying; step S4, preparing ferrite fine powder dispersion liquid: completely dissolving binder and lubricant in acetone, doping soft ferrite fine powder into the acetone solution and uniformly dispersing in the solution; step S5, insulating coating. The beneficial effect of this technical solution is that: uniformly doping an appropriate amount of soft magnetic ferrite fine powder in the passivation layer and the insulating coating layer on the surface of the soft magnetic alloy powder, so that the magnetic permeability of the pressed magnetic parts is significantly improved, and achieves a lower Iron loss, thereby improving the overall performance of the product. |
