galvanic corrosion

[gal′van·ik kə′rō·zhən]
(metallurgy)
Electrochemical corrosion associated with the current in a galvanic cell, caused by dissimilar metals in an electrolyte because of the difference in potential (emf) of the two metals. Also known as contact corrosion.

galvanic corrosion

An electrochemical action which takes place when dissimilar metals are in contact in the presence of an electrolyte, resulting in corrosion.

The Lasagna cell used for the experiments consists of the cell, two graphite electrodes serving as anode and cathode, DC power supply (LG, GP-505), processing fluid reservoirs, heavy dutyrecirculation pump (BVP Instratec), portable data logger (TDS-303, Tokyo Sokki Kenkyujo Co., ltd) for real-time monitoring of temperature, electric current, and voltage across the system (Figure 1).
