Description:
Objective:We are testing magnesium rich coating (MRC) systems as possible chromate replacement coatings for corrosion control of reactive metal alloys. The hypothesis is that the Mg particles embedded in an inorganic or organic matrix coating will sacrificially corrode and provide extended corrosion protection to the underlying metal substrate. Our goal is to understand the role of the Mg particles as sacrificial anodes in MRC’s on aluminum 2024 and 7075 in a corrosive environment. We are currently using electrochemical techniques including electrochemical impedance spectroscopy (EIS), d.c. polarization, and open circuit potential (OCP) monitoring to determine the reliability of the coatings as corrosion inhibitors. In addition, we are also using scanning electron microscopy (SEM), electron probe x-ray microanalysis (EPMA), and x-ray photoelectron spectroscopy (XPS) to determine the state of the magnesium particles.
