摘要
在非水体系中电沉积制备Fe-Pt合金。研究表明:镀液中Fe(II)与Pt(IV)的摩尔比对镀层成分、形貌和磁性能均有较大的影响。随着Fe(II)与Pt(IV)的摩尔比从5∶1增加到13∶1,镀层中Fe的原子分数由7.9%升高到67.5%。当Fe(II)与Pt(IV)的摩尔比为11∶1时,镀层中Fe的原子分数为52.5%。SEM研究表明:随着镀层中Fe的原子分数的升高,细小粒状镀层变为鳞片状镀层,并伴有裂纹。镀层的矫顽力随镀层中Fe的原子分数的增加先增大后减小。当镀层中Fe的原子分数为52.5%时,镀层的矫顽力达到44kA/m。
The Fe-Pt alloy coating was prepared in a non-aqueous system.The research shows that the molar ratio of Fe（II） and Pt（IV）in the plating solution has a significant influence on the composition,morphology and magnetic properties of the coating.As the molar ratio increases to 13∶1from 5∶1,the atom fraction of Fe in the coating goes up from 7.9%to 67.5%.And when molar ratio is 11∶1,the atom fraction of Fe in the coating is 52.5 %.The SEM investigation indicates that along with the increasing of the atom fraction of Fe in the coating,the surface morphology of the coating changes from granular to squama-like structure with cracks.As the atom fraction of Fe in the coating increases,the coercivity of the coating increases first,and then decreases.When the atom fraction of Fe in the coating is 52.5 %,the coercivity of the coating reaches 44 kA/m.
