Cyclic voltammetry, potentiostatic and galvanostatic deposition were performed at different temperatures, from 25°C up to 100°C. The morphology of the deposits was investigated by SEM and AFM, and their composition by EDX. The stoichiometry of the alloys was calculated from the EQCM data, based on Sauerbrey's equation. We could show that for thin films electrodeposited on gold electrodes, one can tune their morphology, and in the case of the alloys, also their composition, by modifying the deposition current or potential, as well as by modifying the temperature of the electrolyte. The morphology of the deposits changed gradually with increasing the amount of Mn in the electrolyte from a polyhedral like structure for Al films to round granules for the AlMn alloys. The mechanism for electrodeposition and dissolution of Al and AlMn alloys were analyzed and discussed based on the EQCM data. article Wolff, Elisabeth VerfasserIn Author aut Bund, Andreas 1969- VerfasserIn Author aut (DE-588)12967477X Technische Universität Ilmenau Fakultät für Elektrotechnik und Informationstechnik host institution his Bd. 164 (2017), 8, Seite H5263-H5270 164, 2017:8<H5263 Technische Universität Ilmenau, Universitätsbibliothek Journal of the Electrochemical Society Enthalten in 1945-7111 dbt_mods_00038418 https://www.db-thueringen.de/receive/dbt_mods_00050011 object in context https://www.db-thueringen.de/servlets/MCRFileNodeServlet/dbt_derivate_00054363/1945-7111_164_2017_8_H5263-H5270.pdf raw object https://www.db-thueringen.de/rsc/thumbnail/dbt_mods_00050011.png preview http://uri.gbv.de/document/gvk:ppn:898511585 uri
