AI Technical Summary

Problems solved by technology

At present, metallizing the surface of ferrite materials is an effective means to enhance the above-mentioned properties of ferrite materials, but ferrite materials themselves are sintered at high temperature, and their physical and chemical properties are relatively stable, so it is not easy to roughen and metallize. processing
[0004] According to reports, some surface metallized ferrite materials have problems in the bonding force between metal and substrate and thermal shock resistance, which cannot meet the needs of technological development. The reason is that the surface of existing ferrite materials is rough. There are defects in the chemical roughening process, especially the formulation of the roughening solution, which leads to poor roughness and uniformity of the substrate surface after chemical roughening, which ultimately affects the effect of metallization treatment
On the other hand, some roughening processes have problems of environmental pollution or high cost, which is not conducive to the industrial application of the process
