Popis: Corrosion and wear mechanisms play a significant role in the degradation of components in various domains such as the petroleum industries, the automobile sector, and manufacturing and biomedical applications. The complex mechanisms of both corrosion and wear, including synergism, need to be well understood in order to design any system with maximum efficiency possible. This chapter is a brief on the concepts of electrochemistry in relation to tribocorrosion concepts. A three-electrode potentiostat system has proved to be a powerful tool in analyzing the chemical interactions within a specimen. The current–voltage response of the system enables the study of behavior of the surface and subsurface mechanisms in the specimen under existing tribocorrosive conditions. The passivation behavior in materials can be revealed with a detailed examination of electrochemical techniques. It also enables the monitoring of the response of coatings in the components in order to provide resistance against tribocorrosive attack. Various electrochemical techniques, such as open circuit potential, electrochemical impedance spectroscopy, polarization analysis, and their application in tribological systems, are discussed.
