Electrodeposition of high entropy alloy thin films and nanowires — •Mirko Gabski, Martin Peterlechner, and Gerhard Wilde — Institute of Materials Physics, University of Münster, Münster, Germany

High-entropy alloys consisting of four of more elements in nearly equiatomic concentrations have attracted attention as structural materials due to their favorable physical and mechanical properties, especially at elevated temperatures as well as improved corrosion and oxidation resistance when compared to more common alloys. The aforementioned properties make high-entropy alloy an interesting choice as a material for the coating of metal parts. In this work electrodeposition is used to obtain thin films of an AlCoCrFeNi alloy to investigate the influence of the deposition conditions on its composition and morphology using energy disperse X-ray spectroscopy and scanning electron microscopy. Furthermore the fabrication of nanowires is carried out utilizing nanostructured anodic aluminum oxide as a template to investigate the influence of the nano-confinement on the deposition process and the resulting microstructure.
