16.1 INTRODUCTION
The scanning Kelvin probe (SKP) is a technique introduced into corrosion science
only recently by the group of Stratmann (1-10). The technique is unique insofar as it
allows a noncontact measurement of electrode potentials, and therefore, also corro-
sion potentials. It is used instead of electrochemical reference electrodes and can
measure electrode potentials through insulating dielectric media, such as air or
polymeric films. It is mainly used where standard electrochemical techniques,
which require a finite electrical resistance between working and reference electrodes,
will fail.
