Technical Abstract: Corrosion of materials is one of the most serious and challenging problems faced worldwide by industry. Dry lubricants reduce friction between two metal surfaces. This research investigated the inhibition of corrosive behavior a dry lubricant formulation consisting of jet-cooked corn starch and soybean oil on SAE 1010 steel. Electrochemical Impedance Spectroscopy (EIS) was used to evaluate the corrosion inhibition of starch-soybean oil coatings containing varying amounts of soybean oil loading. EIS of control starch samples (0% soybean oil) indicated minor protection up to approximately twice that of bare steel and the incorporation of soybean oil in a composite achieved protection up to 10 times that of the control sample.
