Electrochemical corrosion is also known as what type of corrosion?

Electrochemical corrosion is fundamentally tied to the principles of electrochemistry, where the corrosion process typically occurs via the transfer of electrons between different metal surfaces or within a single metal surface. The term that most closely aligns with the mechanisms of electrochemical processes in the context of corrosion is galvanic corrosion.

Galvanic corrosion occurs when two dissimilar metals are in contact in the presence of an electrolyte, creating a galvanic cell. In such a scenario, one metal acts as the anode, where oxidation (loss of electrons) occurs, leading to corrosion, while the other metal acts as the cathode, where reduction (gain of electrons) takes place. This interaction is a quintessential example of electrochemical activity.

Recognizing that electrochemical corrosion involves reactions at the atomic level spurred by electronic transfer between metals highlights its identification with galvanic corrosion. Consequently, the terminology used to describe this process emphasizes the role of electrical currents and potential differences between metals, which is not accurately captured by the term single-metal corrosion. This form occurs without the involvement of another metal and doesn't accurately reflect the dual-metal interactions characteristic of electrochemical processes.

Thus, galvanic corrosion is the appropriate term that defines the nature of electrochemical corrosion, given its reliance on
