Electrochemical Fundamentals of Corrosion and Corrosion Protection

2017
In this chapter, we outline the corrosion process and corrosion protection, which are the basis of the more quantitative treatment presented in the following chapters. The corrosion process in aqueous solution is made up of electrochemical reactions consisting of oxidation of metallic materials and reduction of environmental substances.

Electrochemical Nature of Corrosion

CORROSION 1976, 1976
The electrochemical nature of corrosion would be only of minor or academic interest to the corrosion engineer if it provided merely an additional method of measuring average corrosion rate. The standard gravimetric method, of weighing the amount of metal reacted during a specified time, can yield adequate accuracy when good descaling procedures are ...

Processes of Electrochemical Corrosion

Corrosion, 1958
Theoretical considerations involved in determining the potential of hydrogen and oxygen electrodes are reviewed briefly. Overvoltage is discussed in detail. The various connected stages involved in the process of the passage of ions into solution are outlined. Use is made of the Evans diagram for real processes.

Fundamentals of Electrochemical Corrosion

2000
Fundamentals of Electrochemical Corrosion covers the underlying chemistry and materials science associated with the corrosion behavior of metals in aqueous environments. It begins with a review of corrosion processes and the reactions that occur in the interface area between the metal and corrosive media.

Computerized Electrochemical Corrosion Monitoring

CORROSION 1987, 1987
Abstract Corrosion rates were determined by curve-fitting polarization data using nonlinear regression analysis. Continuous corrosion rate monitoring was implemented thru the use of repetitive scans and real time calculations. Polarization data was fit to the more appropriate of two electrochemical models of the corrosion process: an ...

Electrochemical Corrosion Theory

1993
The driving force for corrosion is the potential difference developed by the corrosion cell $${{E}_{\text{cell}}}=E_{\text{red}}^{\text{cat}}-E_{\text{red}}^{\text{anode}}$$ (2-17) However, the cell potential does not correctly predict the corrosion rate, and it is the corrosion rate that is the essential determiner of a metal’s suitability ...

Electrochemical investigations of pitting corrosion

Corrosion Science, 1973
Abstract By using chronopotentiostatic and stepwise potential change experiments with potentiokinetic and galvanostatic testing, the following types of pitting corrosion of stainless steels in chloride-containing solutions have been investigated: sulphate inhibition of pitting; 35%Cr-Fe alloy; Cr-Ni-Mo stainless steels.

Electrochemical mechanism of metall corrosion

Practice of Anticorrosive Protection, 2021
Corrosion that occurs by an electrochemical mechanism is a combination of cathodic and anodic reactions that occur independently of each other. At that, the metal surface is considered to be equipotential one, i.e. the presence of short-circuited microgalvanic pairs on the surface is not a necessary condition for electrochemical corrosion.

Evaluation of Corrosion Inhibitors for CO2 Corrosion Using Electrochemical and Non- Electrochemical Techniques

CORROSION 2001, 2001
Abstract Corrosion control of carbon steel in oil and gas production with the application of chemicals is widely used due to simplicity of application, availability and economic reasons. The successful corrosion control programs require cost effective corrosion inhibitors that retard the corrosion reactions providing protection.
