Problems solved by technology

[0003] Insulation coating is a key technology in the preparation process of amorphous and nanocrystalline magnetic powder cores. The performance of the insulation coating layer is an important factor affecting the high-frequency loss of the magnetic powder core. If the insulation coating layer is incomplete or damaged, the magnetic powder will increase sharply. The eddy current loss between the particles increases the high frequency loss of the magnetic powder core
[0004] In the application of the prior art, the insulation coating process usually uses acidic solution for corrosive insulation coating treatment, and the acidic solution is usually diluted by volatile organic compounds, resulting in an increase in cost and environmental damage; and it is difficult to control the reaction of the corrosion process Larger, prone to uneven coating and excessive local heat release of powder particles, resulting in changes in the amorphous structure of the powder particle surface
At the same time, the corrosion of powder particles will cause the adverse consequences of decreased powder magnetic permeability and increased hysteresis loss.
