The characteristics of a nickel sulfamate/iron chloride plating bath suitable for high rate electrodeposition of NiFe alloys are described. The effects of current density, electrolyte agitation, and content on deposit composition and plating current efficiency are explored via stripping voltammetry using a rotating ring‐disk electrode. Specific plating bath formulations and operating conditions for depositing a wide range of alloy compositions at a variety of growth rates are illustrated. Special attention is given to determination of polarization and electrolyte mixing conditions for plating Permalloy and Invar. X‐ray diffraction studies are used to investigate relationships between alloy composition and crystal structure. The implications for using the plating bath to electroplate composition‐modulated alloys and 3D microstructures are discussed.
