Organic coatings are widely employed in the corrosion protection of most metal surfaces, particularly steel. They provide a barrier against corrosive species present in the environment, due to their high resistance to oxygen, water and ions transport. This study focuses on the evaluation of corrosion protection performance of epoxy paint on the carbon steel surface in chloride environment (3% NaCl) by Electrochemical Impedance Spectroscopy (EIS). The electrochemical behavior of painted surface was estimated by EIS parameters that contained paint film resistance, paint film capacitance and double layer capacitance. On the basis of calculation using EIS spectrums it was observed that pore resistance (Rpore) decreased with the appearance of doubled layer capacitance (Cdl) due to the electrolyte penetration through the film. This was further confirmed by the decrease of diffusion resistance (Rd) which was also the indicator of the deterioration of paint film protectiveness. Microscopic analyses have shown that oxidation dominates the corroded surfaces.

Abstract AK Steel 409 Ultra Form was created for applications needing oxidation or corrosion protection beyond the capability of carbon steel and some coated steels. AK Steel 409 Ultra Form is more formable than standard Type 409 stainless steel and is particularly suitable for parts requiring more complex shapes and improved weldability. Examples of applications include automotive exhaust tubing and stampings. This datasheet provides information on physical properties, hardness, elasticity, and tensile properties as well as deformation. It also includes information on high temperature performance as well as forming and joining. Filing Code: SS-990. Producer or source: AK Steel, Butler Operations.
