一种铁基非晶合金的处理方法
摘要：
本发明提供的铁基非晶合金的处理方法，该方法是将Fe73.5Si13.5B9Cu1Nb3非晶合金进行直流焦耳热处理，控制电流密度为12A/mm2，处理时间为40s，经过此条件处理得到的Fe73.5Si13.5B9Cu1Nb3非晶合金的2θ值、居里温度TC和饱和磁化强度MS均较高，说明该处理工艺得到的Fe73.5Si13.5B9Cu1Nb3非晶合金的软磁性较好；该处理条件下得到的Fe73.5Si13.5B9Cu1Nb3非晶合金的点蚀电位较高、表面点蚀坑数较少，这表明本发明直流焦耳热处理能提高Fe73.5Si13.5B9Cu1Nb3非晶合金的抗腐蚀性能。
摘要（英）：

The invention provides a treatment method for an iron-based amorphous alloy. The method comprises the steps that direct-current Joule heat treatment is conducted on the Fe73.5Si13.5B9Cu1Nb3 amorphousalloy, the current density is controlled at 12 A/mm<2>, the treatment time is 40 s, the 2theta value, the Curie temperature TC and the magnetization strength MS of the Fe73.5Si13.5B9Cu1Nb3 amorphous alloy treated under the conditions are higher, and therefore it shows that the soft magnetism of the Fe73.5Si13.5B9Cu1Nb3 amorphous alloy obtained through the treatment technology is good; and the pitting potential of the Fe73.5Si13.5B9Cu1Nb3 amorphous alloy obtained under the treatment conditions is high, the surface pitting point number of the Fe73.5Si13.5B9Cu1Nb3 amorphous alloy obtained under the treatment conditions is small, and therefore it shows that the corrosion resistance of the Fe73.5Si13.5B9Cu1Nb3 amorphous alloy can be improved through direct-current Joule heat treatment.
