corrosion cell

corrosion cell

[kə′rō·zhən ‚sel]
(metallurgy)
A condition on a metal surface in which a flow of electric current occurs between the metal surface and an electrolyte with which it is in contact sufficient to cause the metal to degrade.

Low crosslinking allows penetration of moisture, oxygen and conductive ions which can establish the corrosion cell at the coating-substrate interface.
The accelerated corrosion was performed in a corrosion cell inside the steel frame.
If the Au surface shows damage or imperfections due to its low hardness, the steel is left exposed, forming a galvanic corrosion cell that intensifies the pitting corrosion.
(2) Specifically, nickel dissolution in a corrosion cell with graphene-coated Ni electrodes was an order of magnitude lower than that of PA- and PU-coated electrodes, even though the graphene coating was approximately 25 and 4000 times thinner than the commercial PA and PU coatings, respectively.
We created a corrosion cell using a potentiostat, three electrodes, and a solution to mimic the metals environment at the corrosion laboratory at Georgia Tech.
When pipeline is laid underground, soil acts as electrolyte in a corrosion cell and corrosion occurs in metal pipeline primarily due to differential corrosion cell.
Accordingly, Sn and Pb materials become the anode and tend to corrode at an accelerated rate, whereas Ag and Cu materials act as the cathode in the so-called corrosion cell. The anode and cathode reactions are indicated in (1) and (2), respectively:

Corrosion tests were performed using EG & G Princeton Applied Research Potentiostat/ Galvanostat Model 273 (Princeton, NJ, USA) and a corrosion cell standardized to ASTM G5.
S1 and S2 were positioned respectively at 64 cm and 49.5 cm from the corrosion cell (Fig.
A failure mechanism that shows up for investigation every month is metallic short (dendrite) formation around contaminated areas, bias voltage and a fluid media (requirements for a corrosion cell).
