中文摘要：
研究了Fe73．5Cu1Nb3Si13．5B9纳米晶合金在0．1mol／L的NaCl溶液中的耐腐蚀性能，及对其软磁性能的影响。实验结果表明，Fe73．5Cu1Nb3Si13．5B9纳米晶合金经0．1mol／L的NaCl溶液腐蚀后溶液中有橙色沉淀物产生，XRD测试表明铁基纳米晶合金腐蚀后仍保留非晶纳米晶双相结构；铁基纳米晶合金有效磁导率口。随腐蚀时间的增加而降低，腐蚀30d后在频率为50Hz、1、100kHz时其有效磁导率μc较腐蚀前分别下降35．9％、35．3％、27．6％，矫顽力Hc由腐蚀前的0．7097A／m增加到1．117A／m，增加了57．4％，磁滞损耗Pu由腐蚀前的1．819J／m^3增加到2．994J／m^3，增加了64．6％，腐蚀后铁基纳米晶合金软磁性能有所下降。
英文摘要：
The corrosion resistance of Fe73. sCu1Nb3Si13.5B9 nanocrystalline alloys in 0. 1mol/L NaCl solution and its influence to soft magnetic properties were studied. The results show that an orange precipitate was produced in the NaCl solution after corrosion, X-ray diffraction show that Fe-based nanocrystalline alloys retain amorphous-nanocrystalline duplex structure after corrosion; the effective permeability of Fe-based nanocrystalline alloys reduce with increasing of corrosion time, after corrosion for 30d, the effective permeability decreased by 35.9%, 35. 3% and 27. 6% at 50Hz, 1 and 100kHz, respectively, coercive force increase from 0. 7097 to 1.117A/m, increased by 57.4%, hysteresis loss increase from 1. 819 to 2. 994J/m^3 , increased by 64.6%, the soft magnetic properties of Fe-based nanocrystalline alloys are decreased after corrosion.
