The
amount of substance transferred per unit time at a specified surface. Using Faraday's law, the
corrosion rate,
, can be formally expressed as an
electric current which at the
corrosion potential is called the
corrosion current,
, e.g. for the anodic
dissolution of one component of a material with
in
and
in
one obtains
,
being the
charge number of the
electrode reaction and
the
Faraday constant.
