摘要
采用电化学方法研究了退火工艺对Fe73.5Cu1Nb3Si13.5B9纳米晶带材耐腐蚀性能的影响。用差热分析仪分析了该纳米晶带材的晶化过程,利用X射线衍射仪对经不同温度退火后的非晶带材的晶态结构进行了分析,并用恒电位法测试了样品在3.5%NaCl溶液中的耐腐蚀性能。结果表明,在3.5%NaCl溶液中,经过不同温度退火后的Fe73.5Cu1Nb3Si13.5B9纳米晶带材的耐腐蚀性能随退火温度的升高呈先增加后降低的趋势,其中530℃退火后的样品具有最好的耐蚀性。
The influence of annealing process on corrosion resistance of Fe73.5Cu1Nb3Si13.5B9 soft magnetic ribbons was studied by electrochemical method.The crystallization process of Fe73.5Cu1Nb3Si13.5B9 nano-grained ribbons was analyzed using differential thermal analyzer.The structure of the annealed ribbon was analyzed by X-ray diffractometer, and the corrosion resistance of the samples was tested in 3.5%NaCl solution through potentiostatic method.The results show that in 3.5%NaCl solution, the corrosion resistance of Fe73.5Cu1Nb3Si13.5B9 annealed ribbon displays the trend of first increasing and then decreasing with the increase of annealing temperatures.The optimum corrosion resistance of Fe73.5Cu1Nb3Si13.5B9 ribbon is obtained after annealing at 530 ℃.
