Abstract Scope |
Electrodeposition has been used for centuries as a relatively simple, robust, and cost-effective method for applying functional and aesthetic coatings to materials. However, fundamental time-dependent microstructural control remains elusive since systematic relationships between process parameters and resulting coating performance are lacking, due to scattered empirical studies and post-mortem correlations. Here, we aim to use in-situ techniques such as x-ray phase contrast imaging and small angle x-ray scattering (SAXS) to control process-structure relationships of electrodeposited Ag and Ni coatings. We will provide results from interrupted deposition experiments and complementary SAXS results, showing potential for spatial resolution at required scales. Cyclic voltammetry and chronoamperometry will be applied to inferentially approximate relevant nucleation mechanisms. Comparisons to conventional measurements by scanning electron microscopy (SEM) with energy-dispersive x-ray spectroscopy (EDS) are also described. Additionally, we will discuss the state of the literature and our plans for transitioning to in-situ measurements for dynamic phenomena evaluation. |
