Abstract Scope Al alloy structural parts are of high interest to realize lightweight automobiles. However, a fast and reliable corrosion protection method for Al alloys is in demand to improve the manufacturing efficiency of automobiles. In this work, open-air plasma assisted organosilicon coatings are formed on automotive Al alloys, such as Al 7075, as novel corrosion barriers. The benefits of plasma-based coating process include reduction of wet chemical use and compatibility with existing plasma jet systems. As-coated Al alloy samples are characterized by a scanning transmission electron microscope and X-ray energy dispersive spectroscopy to investigate the thickness and the composition within the coating and interface regime. Corrosion evaluation of uncoated and organosilicon coated Al alloy samples is primarily conducted using several electrochemical measurements in 3.5% NaCl solution at room temperature. Preliminary corrosion data indicate that the organosilicon coatings are highly protective in anodically polarized conditions for Al alloys in 3.5% NaCl.
