Abstract

Fe–Pd binary alloy films with various alloy compositions (from 7.8 at% Pd to 77.1 at% Pd) were electrodeposited in a novel bath containing the ammonia solution and the ammonium tartrate as complexing agents by changing the bath composition and the current density. The chemical states of the deposited films were analyzed by using ESCA, and the crystallographic structures of deposited films with wide alloy compositions were determined by using XRD and HRTEM. The result indicated that the crystallographic structures of deposited films are the α-Fe solid solution when the Pd content is below 14.3 at% Pd, the mixture of α-Fe solid solution and (γ-Fe, Pd) solid solution with face-centered cubic structure when the Pd content is from 28.5 to 61.6 at% Pd, and the (γ-Fe, Pd) solid solution when the Pd content is from 69.5 at% to 77.1 at%.
