A Mathematical Model for the Periodic Electrodeposition of Multicomponent Alloys

“…An analogous model for potential-controlled electrolysis is also discussed. [12] and [13]. The current-step solution is first required.…”

“…[7] instead of Eq. Using the method of superposition on Equation [7], the concentration expression for an arbitrarily-specified current source is [11] where oi 0 i.n = niFDif(4/3) [12] . .…”

“…The method of superposition has been used previously for single-component, pulsed-current chronopotentiometry by Andricacos and Cheh (41), and there are a number of references in the literature which can be consulted to derive Eqs. [11], [12], and For short times, the series in Eqs. [12] and [13] will not converge.…”

“…[11], [12], and For short times, the series in Eqs. [12] and [13] will not converge. Equation [8] can then be used to express 9i.n and 'lfi.~· For very short times, only the first term i;}_ Eq.…”

“…2, the dimensionless surface concentrations are plotted for a system in which a Nernst diffusion layer is applicable (the dotted curves) and for the more rigorous solution outlined by Eqs. [12] and [13] (the unbroken curves). It can be seen that the two solution techniques yield very similar answers, as would be expected from the close agreement of the respective current-step solutions.…”
