We have investigated a deposited mass ratio represented by the ratio between the actual deposited mass and the deposited mass expected from Faraday's law in nickel pulse electrodeposition. The deposited mass ratio decays exponentially with the pulse current frequency and approaches asymptotically to a constant value at a high frequency. An analytical solution for an electric circuit model equivalent to electrocrystallization and electric double layer well describes a change in the deposited mass ratio affected by the pulse current frequency, temperature, and additive compound. This study shows that the effect of temperature and the additive on the deposited mass ratio is characterized by a cut-off frequency defined by the analytical solution.
