Optimization of Electroplating via Computer-Based Closed Loop Control

Geoffrey Baran, Grant Overby, and Timothy L. Sorey. Central Washington University, Olympia, WA

Reduction potentials, Eocell, exist for a vast number of ionic aqueous solutions. These reduction potentials assist scientists and engineers in real-world applications but vary with changes to environmental parameters, such as pH and temperature outside of standard state. Dynamic approaches to electroplating will be presented that utilize computer-based closed loop control and optimize experimenatal parameters for several galvonic cells. These electrochemical computer-based methods show promise in determining appropriate reduction potentials that vary with environmental parameters. Results will be presented for multi-charged metalic cationic species, such as Ag/Ag+, Cu/Cu2+, and Al/Al3+.
