Coatings are applied to many industrial components for a variety of reasons. For example these coatings could be applied to an engineered component to provide: (a) corrosion protection of the substrate (b) wear resistance of the substrate (c) resistance to fouling. There is a large family of coatings including organic metallic ceramic and combinations of them. There are also a large variety of application methods including thermal spray electroplating and physical vapor deposition. The current paper explores the electrochemical and corrosion behavior of several metallic and non-metallic coatings deposited on stainless steel C450 for corrosion wear and antifouling applications. Most of the tests were performed in 5% NaCl solution pH 4 at 50°C. The monitoring of the corrosion potential of coated and non-coated specimens determined what type of coating will provide corrosion protection to the substrate and electrochemical impedance measurements monitored the evolution of the coating behavior as a function of the immersion time. The electrochemical results correlated well with results from the exposure of coated coupons salt fog (ASTM B117).
