Poly(methyl methacrylate-co-N-vinyl-2-pyrrolidone polymer as inhibitor for Mild Steel Corrosion in Acidic Media
Abstrak
A thorough investigation of a polymer was performed for corrosion of mild steel in 1M HCl solution using electrochemical and surface studies. Infra-red spectroscopy was completed in reflectance mode to detect the adsorption of the polymer on the metal surface. Scanning electrochemical microscopy (SECM) studies were made to detect the localized corrosion reaction at the working electrode. Electrochemical impedance spectroscopy revealed that the efficiency of corrosion inhibition was improved after the addition of polymer in the solution. Polarization studies suggested that the polymer belong to the mixed category mitigators. Scanning electrochemical microscopy (SECM) studies suggested that the surface was insulating in presence of polymer thereby protecting the surface. Scanning electron microscope (SEM) suggested that the surface was less corroded in presence of polymer.
