Abstract

The aim of this study is to investigate the effect of clay nanosheets on the galvanic protection behavior of zinc in scribed areas of polymer zinc-rich coating. The scribed area is a simulation of damage in the coating in such a way that steel gets in contact with a corrosive solution and sacrificial behavior of zinc becomes important. Ultrasonic was applied to disperse nanosheets of clay in the epoxy resin. The clay content in the coating was varied from 0 to 3 wt.-%. The coatings were scratched for studying the galvanic behavior of zinc under damaged condition. Electrochemical impedance spectroscopy, open circuit potential measurements and surface techniques were chosen to investigate the corrosion protection performance of the coating and sacrificial properties of zinc. Transmission electron microscopy illustrated the separations of clay layers which interacted with epoxy resin. In addition, TEM images showed the dispersion of clay nanosheets between zinc particles in coating matrix. Open circuit potential (OCP) measurements showed that with increasing immersion time, the OCP shifted to the less negative potential values. The cathodic protection period and sacrificial properties improved in the presence of clay in coatings. Electrochemical impedance results indicated that addition of 1 wt.-% clay nanosheets enhances the corrosion protection performance of the epoxy zinc-rich coating without decreasing its sacrificial properties after long exposure times.

Kurzfassung

Das Ziel der diesem Beitrag zugrundeliegenden Studie bestand darin, den Effekt von Ton-Nanoblättchen auf den galvanischen Schutz von Zink in geritzten Bereichen von zinkreichen Polmerbeschichtungen zu untersuchen. Die geritzten Bereiche stellen eine Simulation der Beschädigung in der Beschichtung derart dar, wobei der Stahl in Kontakt mit einer korrosiven Lösung kommt und das Opferverhalten von Zink wichtig wird. Ultraschall wurde eingesetzt, um die Dispersion der Nanoplättchen aus Ton in dem Epoxidharz zu erreichen. Der Tonanteil in der Beschichtung variierte zwischen 0 und 3 wt.-%. Die Beschichtungen wurden eingeritzt, um das galvanische Verhalten von Zink in dem beschädigten Bereich zu untersuchen. Es wurden elektrochemische Impedanzspektroskopie, Potentialmessungen unter freier Korrosion und Oberflächen-Analysetechniken eingesetzt, um die Korrosionsschutzwirkung der Beschichtung und die Opfereigenschaften von Zink zu ermitteln. Transmissionselektronenmikroskopie zeigte die Trennung der verschiedenen Zinklagen, die mit dem Epoxidharz in Wechselwirkung standen. Zusätzlich zeigten die TEM-Bilder die Dispersion der Ton-Nanoplättchen zwischen den Zinkpartikeln in der Matrix der Beschichtung. Die Potentialmessungen unter freier Korrosion zeigten, dass mit zunehmender Eintauchzeit das freie Korrosionspotential sich zu weniger negativen Werten verschiebt. Die Zeit des kathodischen Schutzes sowie die Opfereigenschaften verbesserten sich unter Anwesenheit von Ton in den Beschichtungen. Die Ergebnisse der elektrochemischen Impedanzmessungen zeigten, dass eine Zugabe von 1 wt.-% Ton-Nanoplättchen die Korrosionsschutzeigenschaften der zinkreichen Epoxidbeschichtungen verbessert, ohne die Opfereigenschaften nach langen Epositionsdauern zu reduzieren.
