摘要: Abstract Novel Sn–Ni–Fe ternary phases, which never occur in the metallurgical alloys, were successfully prepared by deposition from an electrolyte based on sodium gluconate, using DC electrodeposition conditions. 57 Fe and 119 Sn conversion electron Mossbauer spectroscopy PXRD investigations of these alloys showed that they are amorphous dominantly ferromagnetic. The occurrence Sn–Fe–Ni alloy phase deposits was found to increase with current density applied during deposition. co-deposition kinetics is mainly governed behavior tin–gluconate complex forms electrolyte. high cathodic polarization due discharge causes apparent mass transfer coupled iron. nickel rate independent potential partial co-depositing species.
