中文摘要:
      目的 提高硅钢的磁性能。 方法 采用多弧离子镀技术, 在普通取向硅钢薄板两面沉积高硅FeSi 合金层制得高硅梯度硅钢,并进行热处理,?炱湎晕⒆橹?测量磁性能。 结果 退火态高硅梯度硅钢表面的高硅 FeSi 合金层与基底结合紧密,均匀致密。 高硅梯度硅钢中硅含量呈梯度分布,最表层硅质量分数为 11 . 0% ,随着深度增加,硅含量逐渐降低,在距表面 20 μm 处硅质量分数仍能达到 6 . 5% 。 沉积态高硅梯度硅钢的电阻率 ρ、低频铁损 P10 / 50、高频铁损 P10 / 1k 及磁感应强度 B8 分别为 68 . 6 μΩ·cm,0 . 82W / kg,83 . 3 W / kg 和 1 . 73 T,退火后分别为 63 . 1 μΩ·cm,0 . 44 W / kg,54 . 38 W / kg 和 1 . 89 T。 结论 由于表层高硅 FeSi 合金层的存在,梯度高硅钢的低频磁学性能良好,但高频损耗需进一步改善。
英文摘要:
      Objective To improve the magnetic properties of silicon steel. Methods FeSi alloy coatings with high-silicon content were deposited on the surface of common grain-oriented silicon steel by cathodic arc plasma evaporation, and then a kind of high silicon gradient steel was prepared. The morphologies, content and magnetic properties of the samples were tested. Results FeSi alloy coatings were featured with compact microstructures and excellent adhesive quality with the substrates. The silicon content was 11. 0% ( weight percent) in the surface of coatings, and then the whole sample showed a gradient distribution of silicon. The silicon content was still as high as 6. 5% at a distance of 20 μm from the surface. The resistivity ρ, magnetic properties P10 / 50, P10 / 1k and B8of the samples were 68. 6 μΩ·cm, 0. 82 W / kg, 83. 3 W / kg and 1. 73 T before annealing. After annealing, the abovementioned four indexes became 63. 1 μΩ·cm, 0. 44 W / kg, 54. 38 W / kg and 1. 89 T. Conclusion The low-frequency magnetic properties of substrates were improved with high resistivity, tensile stress and good crystallinity in high-silicon FeSi alloy coatings, and the high-frequency magnetic properties still need to be improved in future work.
