Electrodeposition is a metallic or semiconducting film growth process that consists in the formation of coatings on conductive substrates, starting from metal ion precursors in a suitable solvent and occurring via a charge transfer.
The syllabus of this course focus on:
Electrodeposition of metals. Electrolytes used for electrodeposition. The influence of deposition parameters on the electrodeposition processes. Composition, structure and properties of deposits. Influence of diffusion on the rate of electrochemical process. Homogeneous nucleation. Heterogeneous nucleation. Nucleation mechanisms. Electrodeposition of alloys. Underpotential deposition. Electrochemical techniques for electrodeposition and characterization of deposits.
Principles of electrodeposition in practice. The electrodeposition cell. Current and rate of deposition; rate of deposition and electrode area; rate of deposition and thickness of the deposited layer. Current density and current efficiency; current efficiency and rate of deposition. Potential and current distribution. The Hull cell. Throwing power of a plating solution. Factors which determine the throwing power. Determination of the throwing power of an electrolytic bath: the Haring-Blum cell. Types of industrial electroplating processes; practical examples. Electroless deposition. Electrophoretic deposition.
Laboratory classes will be used to exemplify the preparation and characterization of the electrochemical deposition of metallic films.
To provide training and advanced understanding on the electrodeposition mechanisms of metals and metal alloys.
Analysis of industrial electrodeposition processes, relating the technology with the fundamental principles. It is intended that students can conceptualize in scientific terms the phenomena taking place in industrial electrodeposition processes.
