Abstract
It has been argued in various places that prediction of the
behaviour of corrosion allowance materials is easier than for
passive materials which may undergo localised corrosion. The
mechanisms of localised corrosion are presented in this paper,
together with supporting experimental facts. Important parameters
are pH and aggressive ions in the environment, protection potential
and changes of electrode potentials with time.
