Abstract: Disclosed are methods of treating a metal to improve the metal's corrosion resistance. The method includes applying, to the surface of the metal, a coating which comprises magnesium powder and a binder. The present invention also relates to a coating composition that includes magnesium powder and a silane modified epoxy isocyanate hybrid polymer or prepolymer. The inventors have found that corrosion resistance (as determined by Prohesion™ exposure in accordance with ASTM D5894-96, which is hereby incorporated by reference) in excess of 3,000 hours on 2024 T-3 aluminum alloy can be achieved with the methods and coating compositions of the present invention.

Abstract: A system and method for potentiostat calibration includes a conductive substrate, a model film placed on the substrate, an electrolyte, and a potentionstat for obtaining calibration data from tests conducted on the model film. The electrolyte is disposed at a first side of the model film opposite the substrate, and in electrical contact with the model film. The potentiostat includes a working electrode, a reference electrode, and a counter electrode. The working electrode is electrically connected to the substrate, and the reference and counter electrodes are positioned at the electrolyte.
