概述了用Fe78Si9B13非晶带材制备C型铁芯的方法，通过电子显微镜、软磁交流测量仪、电感测试仪等研究了非晶C型铁芯切割面微观组织结构与损耗和电感的关系。结果表明：酸液腐蚀可恢复铁芯切口部分非晶带材片层间绝缘，进而降低铁芯损耗值，且频率越高效果越明显，电感量在此过程中上升；酸液腐蚀C型铁芯切割面是恢复片层间绝缘、降低C型铁芯损耗值的有效途径之一。
Abstract
The process method to produce amorphous C-core with Fe78Si9B13 amorphous alloy strips was introduced. The relationships of cross section’s microstructure to core loss and inductance were researched by scan electron microscope (SEM) and soft magnetic AC instrument and inductance tester. The results of research show that the amorphous strip layer insulation in cross section can be recovered by acid corrosion, which led to the decrease of core loss. The decreasing value is more obvious with higher acid corrosion frequency, and inductance is increased during acid corrosion process. Acid corrosion on cross section of amorphous C-core is an effective method to recover layer insulation and decrease core loss.
