SOME ASPECTS ON PULSATORY CURRENT ELECTRODEPOSITION. Authors: G. MOCANU, D. POP. |
||||||
Abstract: It has been noticed that the quality parameters of electrolytic deposition are higher when an alternative current regime is used, i.e., when the voltage source controlling the electrolyte bath is pulsatory. Two temporal scales are characteristic to the source and thus to the process, the duration of the on-phase and the duration of the off-phase (also called relaxation time). A method is proposed to further improve this setting by allowing for a time-variable relaxation time. A full analytical treatment is presented, including the solution of the associated convection-diffusion equation for the ion concentration in the electrolyte bath. Keywords: electrodeposition, concentration, diffusion. |
