OXYGEN IS ONE OF THE MOST DESTRUCTIVE FORCES IN MODERN
SOCIETY, ESPECIALLY BECAUSE WE BUILD AND MANUFACTURE
USING METALS. FROM RUSTING IRON REBAR, TO STRESS
CORROSION CRACKING ON ALUMINUM HULLED CRAFT, TO THE
EXTREMELY CORROSION RESISTANT NICKEL ALLOYS USED FOR
POTENTIAL NUCLEAR WASTE STORAGE, CORROSION HAPPENS.
GAMRY HAS BEEN AT THE FOREFRONT OF ELECTROCHEMICAL
CORROSION TESTING SINCE OUR INCEPTION IN 1989.

Corrosion is the chemical or electrochemical reaction between a material,
usually a metal, and its environment that produces a deterioration of the
metal and its properties (see ASTM G 15). A chemist would classify
corrosion as an oxidation, an electron-transfer reaction involving the loss of
electrons.
Since corrosion is an electrochemical process, it follows that electrochemical
techniques and electrochemical instrumentation can be used to study the
corrosion process. Indeed, a number of electrochemical techniques have
been developed over the years especially for the measurement of corrosion
processes. Electrochemical techniques are very well accepted by the
corrosion community and it is the rare corrosion laboratory that does not
make routine use of these tools.

3.
the popularity of electrochemical techniques
for corrosion measurement are
They are fast.
They are sensitive.
They are accurate.
They are versatile.
Most are non-destructive

4.
corrosion measurement techniques breakdown into DC, AC, and Noise.
All Gamry potentiostats can be set up to
perform DC, AC, and Noise corrosion
testing, though for very low corrosion rate
systems, the Reference 600 is the best
choice due to its superior low current
performance.

new to corrosion research
If you are new to corrosion research and electrochemical corrosion testing in
particular, you may want to start with a quick look at our Application Note
Basics of Electrochemical Corrosion Measurements, and consider enrolling in
a short course like the one taught at Pennsylvania State University every
summer.
already familiar with the
corrosion process
For those who are already familiar with the corrosion process, please
have a look at our Application Notes covering Electrochemical Impedance
Spectroscopy, and consider swapping your Rp/Ec Trend out with EFM
Trend.
