Electrochemical Testing
Electrochemical tests are tests which utilize the monitoring and/or control
of the corrosion current and potential of an electrode of a particular
material in a corrosive environment to determine information regarding:
- Instantaneous corrosion rate.
- Susceptibility to localized corrosion.
- Potential for galvanic corrosion.
- Characterization of anodic and cathodic reactions.
These tests typically give more information than common corrosion coupon
tests by virtue of the fact that the potential on the specimen can be
controlled thereby accelerating or retarding electrochemical reactions
related to corrosion on the surface.
Electrochemical test techniques are useful in the study of corrosion
resistant alloys, active/passive behavior, inhibition and stress corrosion
cracking.
