COz Corrosion Stndy by Electrochemical Impedance Spectroscopy (EIS) and Linear Polarization Resistance (LPR)

Corrosion is a phenomenon where metals deteriorate to their natural oxide states after
undergoing an electrochemical process in the present of electrolyte and oxygen. The
process takes place where the electron leaves the metal in an oxidation reaction and
enters the solution at an area known as anode. Cathode is the area where the electrons
return and react with the electrolyte compounds depending on the environment and type
of electrolyte. The electron path, which could be the base metals between different metals
complete the electronic circuits. C02 corrosion is one of corrosion type and can be
measured by a lot of measurement teclullques. Common types of measurement technique
are Electrochemical Impedance Spectroscopy (EIS) and Linear Polarization Resistance
(LPR) techniques. The environmental factors such as pH, temperature, oxygen content
and percentage of electrolyte can affect the corrosion rate.
