本发明介绍一种隔离涂层,运用这种含有有机或无机酸的酰胺或酰亚胺的隔离涂层制作具有单取向性且导磁导μ_(10)≥1850高斯/奥斯特的电磁硅钢的工艺。实验室试验已表明:有些AlN抑制的取向硅钢在含有氮气保护的气氛中进行最终退火时,取得了好的磁性;而同样的退火在氢气保护下进行时则不能得到满意的磁性。推测这是
The present invention describes an insulation coating using this barrier coating containing an amide or imide of an organic or inorganic acid to produce a magneto-silicon steel having a unidirectional permeability and a permeability of _ (10) ≧ 1850 Gauss / Oersted Process. Laboratory tests have shown that some AlN-inhibited oriented silicon steels achieve good magnetism when subjected to final annealing in a nitrogen-containing atmosphere, while the same anneal does not provide satisfactory magnetism when carried out under hydrogen protection. Speculate this is
