Corrosion is prevalent in today's society. Paint is applied to ships and aircraft to minimize corrosion. The most common anti-corrosion ingredient in paint has been chromium (VI), which is highly toxic during application. Studies are being done to find a replacement anti-corrosion additive that is less toxic than chromium (VI). Currently, paints with differing amounts of cerium oxide nanoparticles are being evaluated for anti-corrosion properties. Scanning Electrochemical Microscopy makes this determination by applying a voltage to the paint samples; differences in measured current are used to determine how effective the cerium oxide nanoparticles are at inhibiting corrosion.
