Mixed mode oscillations in an electrochemical reactor

Zdzislaw Trzaska 1


The paper subject is focused on modelling electrochemical processes during a deposition of nanostructured materials on a metallic substrate. Fundamentals of electrocrystallization processes and parameters influenced the final quality of resulting products are considered. To quantify the evolutions of the electrochemical reactor processes with respect to time an equivalent electric circuit has been established. Two types of periodic supplying currents were taken into considerations: bipolar pulse current and sinusoidal rectified current. Results of performed computer simulations of electrocrystallization processes with the focus on mixed mode oscillations (MMOs) as the dynamical switches between small amplitude oscillations (SAOs) and large amplitude oscillations (LAOs) are presented. The established circuit model can lead to methods for fast treating large quantities of electrocrystallizator  data and extracting from them kinetic parameters importantly influenced the structure of the produced materials.
