Abstract
CMT measurements and electrochemical (EC) measurements of
corrosion rate are generally in agreement, when only
electrochemical dissolution of metals in acid take place. However,
dissolution of oxide layers and other acid-consuming reactions can
cause CMT measurements to exceed EC measurements. It is shown that
when aluminium dissolves in alkali, CMT measurements can also be
applied, but in this case requiring titration with alkali.
Titration with alkali is also required in a special situation,
where corrosion of nickel in an acid solution and subsequent
formation of a nickel complex results in liberation of excess of
acid. A non-electrochemical dissolution of nickel is evidenced in
the latter case.
