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.
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.

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.
The partially heat-activated WOA residues (moisture-absorbing) were, by themselves, not corrosive; however, combined with high chloride residues from a HASL flux (marginal cleaning during board fabrication) the moisture absorbed by the flux was enough to establish the conditions for a corrosion cell.
If the water heater is connected directly to a copper piping system, the steel of the tank and the copper in the pipes can set up a galvanic corrosion cell that will cause the tank of the water heater to corrode away rapidly.
However, serious corrosion-related leaks and breaks can manifest themselves in a matter of weeks if significant changes occur to any one of the four components of the corrosion cell (anode, cathode, metallic path and electrolyte).
ANODE--Half of an electrolytic corrosion cell in metal from which metal dissolves, often leaving pits.
We wanted to avoid the possibility of a galvanic corrosion cell between the cast iron casing and the stainless steel impeller and sleeves," he says.
The admixture provides corrosion protection to anodic and cathodic areas of corrosion cell sites.
