| Abstract Scope |
This work will present on the process optimization of molten salt electrodeposition for refractory metal coatings, such as tantalum. Refractory metal coatings are critical for a variety of industries including aerospace, automotive, and nuclear. This investigation will study various system parameters to achieve the desired thickness and morphology of the refractory metal coating, for the desired application. This includes charge, current density, and the possible application of a rest or oxidation step. Other system parameters to be studied include examining different precursors and their ion speciation, and salt preparation steps, such as pre-electrolysis cleaning and dissolution time of the analyte. Electrochemical analytical techniques, such as cyclic voltammetry and chronoamperometry, will be used to measure ion concentration and the deposition mechanisms. Characterization of the coating post electrodeposition will include SEM/EDS, XCT, XRD and profilometry.
