Electroplating Fundamentals

This lecture covers the fundamentals of electroplating, focusing on topics such as mass transport in a boundary layer, concentration boundary layers, and velocity boundary layers. It delves into the development of these layers for an arbitrary surface, the creation and annihilation of species A, and the transport mechanisms involved. The lecture also discusses the limiting diffusion current, the structure of electrodeposits, and the principles of alloy plating. Various electrochemical characterisation methods, the electrochemical double layer, and the kinetics of electrode reactions are explored. Additionally, the lecture touches on biosensors, biomedical sensors, and the advantages of microfabricated electrochemical devices.
