Abstract Organosilicon layers were deposited on galvanized steel to give a protective coating against corrosion. HMDSO was atomized and injected into a DBD plasma at atmospheric pressure. Plasma‐polymerized HMDSO layers were different when HMDSO nanodroplets reacted directly in the plasma area or when such droplets reacted with the plasma once deposited on the surface. Addition of a plasma curing step was also studied. Influence of the deposition method on the properties of ppHMDSO layers was also studied. Layer structure was measured by SEM and interferometry, and its chemical structure was analyzed by FTIR and XPS. Corrosion resistance, which was measured by electrochemistry, was significantly increased when a plasma curing step was performed.
