Abstract
AbstractThis work evaluates best practices for managing the corrosive effect of magnesium-chloride-based deicers on the metallic components of equipment fleets. The first part of this study evaluates the effectiveness of salt remover for washing bare metals. A dip-dry test was employed to simulate the field conditions. Carbon steel (C1010), aluminum alloy (Al1100), and stainless steel (SS304L) were used in the test program to evaluate the use of water, soapy water, and a commercial salt remover in washing practices. The corrosion behavior of metals was studied using linear polarization and electrochemical impedance spectroscopy measurements. Digital photos and scanning electron microscopy revealed the surface morphology of corrosion coupons. The salt remover could significantly enhance the corrosion resistance of carbon steel and stainless steel in a 30%-by-weight MgCl2 solution, but not that of the aluminum alloy. Further investigation focused on the evaluation of an innovative sugar beet by-product for use as a deicer additive. A modified dip-dry test was employed to simulate the field conditions. Bare and coated C1010 samples were used to evaluate the potential anticorrosion benefits of this green deicer additive. The corrosion behavior of the samples was characterized using electrochemical impedance spectroscopy. The use of sugar beet by-product can enhance the corrosion resistance of carbon steel and the mechanism of protection is the formation of a temporary protective layer on the metallic surface.
