Abstract Scope |
Electrodeposition is a non-equilibrium process as it takes place under cathodic overpotential. Consequently, the phases formed are often not in thermodynamic equilibrium, and may be either undersaturated or supersaturated compared to their counterparts in the equilibrium phase diagram. In this presentation, examples such as formation of metastable fcc-Re and hcp-Ni in the Re–Ni and Re–Ir–Ni systems and non-equilibrium phases in the Zn–Ni system will be given. The effects of high internal tensile stresses developed in the coating due to co-deposition of hydrogen, hetero-epitaxial growth and hydride decomposition on the microstructure will be discussed. In light of Prof. Lavernia’s seminal contributions to additive manufacturing of metals, a novel atomic force microscope-based three-dimensional meniscus-confined electrodeposition developed in my lab will be presented. |
