ELECTROCHEMICAL INVESTIGATION OF THE CORROSION BEHAVIOUR OF MICRO ALLOYED STEEL AND COLD FORMED STEEL IN HCL SOLUTION

This paper presents the development and the technical importance of the Micro alloyed steel for different microstructural conditions. Weight loss, Non Electrochemical method, and Electrochemical Impedance Spectroscopy (EIS) techniques, optical microscope and XRD have been used to study the electrochemical behavior. Steel is an alloy of iron and carbon. Steel is the most useful material for building structures with strength of approximately ten times that of concrete, Steel plays a fundamental role in the development of modern societies. Corrosion is the destructive attack of a metal by chemical or electrochemical reaction with its environment. Deterioration by physical causes is not called corrosion, but is described as erosion, galling, or wear. The influences of the low temperatures on the mechanical properties of micro steel and cold formed steel are compared and their differences are discussed. The corrosion patterns and rust characteristics of the corroded steel bars were examined
