Corrosion Failure
A corrosion failure
occurs when the metal wears away
or dissolves or is oxidized due to chemical reactions, mainly
oxidation. It
occurs whenever a gas or liquid chemically attacks
an exposed surface, often a metal. Corrosion is
accelerated by warm temperatures and by acids and
salts. Corrosion products (e.g., rust,
patina) can remain on the surface and protect it. Removing
these deposits re-exposes the surface, and corrosion
restarts and/or
continues. Some materials resist corrosion
naturally; others can be treated to protect (e.g.,
by coating, painting, galvanizing, or anodizing)
against corrosion. An example of salt water
corrosion of a cast iron bath tub is shown in the
photograph below.
