摘要/Abstract

摘要： 采用电流化学镀工艺，在直径为100 μm的铜丝上通以150 mA的直流电流，制备了NiCoP/CuBe复合结构丝，研究了镀液pH值对复合结构丝镀层的形貌、镀速、成分、磁性能和GMI效应的影响.研究发现，镀液pH值的改变会引起致密性、镀速、镀层成分和磁性能的变化，结果影响到材料的磁阻抗比和特征频率.pH值为8.4时，得到最大阻抗比为868%.

关键词: pH值, 复合结构丝, 化学镀, GMI效应

Abstract: Composite wires of 100 μm diameter CuBe coated with a layer of NiCoP were prepared by chemical plating, and dc current of 150 mA got through CuBe wires during the process. The influence of pH value on the composite wires was studied in terms of morphology, deposition speed, composition, magnetic property and the GMI effect. The results showed that the pH value influenced GMI effect and critical frequency by changing the roughness of materials, deposition speed, the coating composition and magnetic structure. The maximum GMI effect of 868% is obtained at the pH value of 8.4.

Key words: pH value, composite wire, chemical plating, GMI effect
