<p>Fe–Ni alloy was electroplated on Ti rotating cylinder electrode(RCE) at various conditions, varying rotating speed and bath conditions. The inhibition of Ni reduction increased with rotating speed of the electrode, leading to higher Fe content of deposits. The composition change with rotating speed was more apparent for RCE than stationary planar electrode, however, the trend of compositional change in the thickness direction appeared the same regardless of cathode type. Hydrogen evolution was also promoted with rise of rotating speed, causing more brittle deposits and decrease in current efficiency. To obtain complete Fe–Ni invar film (36–40 wt% Ni) without damage, not only the rotating speed but also the bath composition controlled. The Fe content of deposits increased with concentration of Fe²⁺ in the bath, and the composition of films were within target range except the Fe-richer back side than front side.</p> Graphical Abstract <p></p>
