Fundamentals and principles of electrode-position

Abstract

In this chapter we explain the fundamentals of electrodeposition starting with the principles of electrolysis, and electrodeposition cells. The electrochemical fundamentals play a vital role in electrodeposition, then these will be discussed in details and modern approaches for the investigation of thermodynamics and kinetics aspects are reviewed. Nucleation and growth of electrodeposition and their modes including overpotential (OPD) and underpotential (UPD) deposition control the microstructure and consequent properties, as will be introduced. Characterisation methods of initial stages of electrodeposition and other stages will be explained using conventional electrochemical techniques and modern microscopical and nanoscopical techniques. The enhancement of electrodeposition process by application of external forces such as magnetic and ultrasound will be explained.
