Materials
that do not form protective surface films may be protected by the application
of other coating materials. The table below shows some material types and
their comparative properties.
·
Local
failure of any of these films may give rise to local corrosion of the base
material. The exception is when the film is able to provide anodic protection
in the corrosive environment. |
