摘要
对电沉积得到的Ni-Fe坡莫合金箔,在氢气气氛下进行退火处理,退火温度分别为850,1000和1150℃,保温时间均为5h.在扫描电子显微镜(SEM)和光学显微镜下观察合金箔断面和表面的显微结构,利用XRD检测合金箔的晶体结构,利用软磁材料直流磁性测试仪装置测得合金箔的直流磁特性.实验结果表明:在850～1150℃温度下热处理时,退火温度越高,合金箔的直流磁性能越好;经过退火热处理后合金箔的晶粒明显长大,而且合金箔存在明显的择优取向.
Electrodeposited Ni-Fe permalloy foils was annealed under hydrogen atmosphere at 850, 1000 and 1 150 ℃ for 5 h, respectively. The microstructures of cross-sections and surfaces were observed by SEM and optical microscope, the crystal structure was studied by XRD, and the direct-current magnetic properties were measured by direct-current magnetic properties testing equipment. The results indicate that when the annealing temperature is between 850 and 1 150 ℃, the direct-current magnetic properties improve with increasing temperature. After annealing, the crystals of the permalloy foils grow up rapidly and present obvious preferred orientation.
