摘　　要：利用扫描电镜和能谱实验,探究了水溶液体系电沉积工艺制备Fe-La-P合金薄膜中添加剂和电流密度对其形貌及成分的影响.结果表明:以H3PO4作为添加剂可以实现Fe-La-P合金薄膜的诱导共沉积.Fe-La-P化合物含量随电流密度的增大先增加后减少.Fe-La-P化合物含量在电流密度I A=10 A/dm^2时达到极大值,其含量在薄膜中所占比例为10.26%.The effects of additives and current density on the morphology and composition of Fe-La-P alloy films prepared by the aqueous solution electrodeposition process were investigated by using SEM and EDS.The results show that H3PO4 can be used as an additive to induce co-deposition of Fe-La-P alloy films.The content of Fe-La-P compound increased first and then decreased with the increase of current density.The content of the Fe-La-P compound reached a maximum when the current density of IA was 10 A/dm^2,and its content accounted for 10.26% in the film.
