AIRCRAFT COATING - Magnesium approach inhibits corrosion as well as chromate ============================================== Tuesday, 26 March 2013 After three years usage in real life no complains - that is a wonderful result for a chrome-substitution. . Dr Gordon P. Bierwagen of North Dakota State University’s Department of Coatings and Polymeric Materials will be awarded: his invention of magnesium–rich primers protects aluminum alloys in the same way that zinc-rich primers provide sacrificial protection for ferrous substrates. When it was first proposed, the prevailing, external, scientific opinion was that the magnesium concept would not work, but Bierwagen and his co-workers have proven and developed a viable technology that has now been licensed by AkzoNobel. . After three years of usage with magnesium no corrosion . Laboratory and field testing indicate that this magnesium approach inhibits corrosion as well as the chromate inhibitor. The magnesium-rich system is in service trials on both military cargo and fighter aircraft, with no reports of problems after three years. This is a substantial accomplishment that has considerable benefits for the environment and human health while maintaining the necessary high level of performance. . Research gets award . Bierwagen will receive the Roy W. Tess Award in Coatings for 2013. . At North Dakota State University, Bierwagen carries out research on coatings formulation concepts and corrosion, including the effect of coatings on corrosion and the development of anti-corrosion coatings. Specific areas of focus include: electrochemical testing of coatings, the use of conducting polymers as corrosion inhibitors, the invention of magnesium-rich coatings as replacements for hexavalent chromium-containing primers, and the use of electrochemical sensors embedded in coatings. european-coatings/Raw-Materials-Technologies/Applications/Protective-Marine/Magnesium-approach-inhibits-corrosion-as-well-as-chromate
