eLECTROLYTE
|
|
Four conditions must
exist before metal corrosion can occur. |
a. A metal which has a tendency to corrode must
be present (the corroding metal is called the anode); b. A dissimilar conductive material (the cathode), which has less tendency to corrode than the anode, must be present (a dissimilar metal may be a different metal, a protected part of the same metal, or conductive plastic); c. A conductive liquid (electrolyte) must connect the anode and cathode (so that ions can carry electric current between them); and d. Electrical contact between the anode and cathode (usually in the form of metal-to-metal contact) must exist so that electrons can move between the anode and the cathode. |
