Simple N Compounds Electrochemical Behavior of Steel in Aqueous Solutions

Abstract

Chemical polishing or electropolishing, instead of mechanical polishing, are recommended for the attainment of metallic surface polishes without the introduction of contaminates or tensions in the surface layers of the metal. The fundamental difference between the chemical and electropolishing processes is that in the latter anodic currents/potentials are used to help in the dissolution and passivation of the metal. The elctropolishing process inhibited with different ratio by addition of amide derivatives with concentration range 1x10^-6 to 5x10^-3M .The results reveal that amides have strongest inhibitive effect ranging from 4 to 38 %.  Thermodynamic parameters as well as adsorption isotherms were driven.
