Rezumat: The corrosion resistance of galvanic coatings (e.g. electrodeposited Zinc, as hereby presented) largely depends on their morphology and crystallographic orientation. The presence of organic nano- aggregates was found to positively alter the aforementioned characteristics, resulting in increased corrosion resistance due to enhanced barrier properties, favorable composition (e.g. formation of zinc oxides rather than zinc oxy(hydroxy)chlorides) and self-healing mechanisms. The paper presents a comparative study on recently developed nano-composite galvanic zinc layers, discussing their electrochemical behavior (recorded via Electrochemical Impedance Spectroscopy, Scanning Vibrating Electrode Technique and Potentio-dynamic Polarization) and surface morphology (via Scanning Electron Microscopy) after treatment in 5% NaCl.
