The future of corrosion science begins here
During corrosion of two connected electrodes, fluctuations in corrosion potential
and couplig current are often observed. Such fluctuations are called Electrochemical
Noise and contains important information on the corrosion process. For example,
events involving rapid metal dissolution (anodic) or hydrogen discharge with gas
bubble formation and detachment produce significant electrochemical noise.
The current and potential fluctuations are usually of relatively low amplitude, but
can be easily measured with commercially available instruments.
Electrochemical noise analysis can be used to identify the type of corrosion (general
or localised) and the corrosion rate without the application of any probing potential
or current signal.
