Finding good protective coatings that hold up to harsh marine
environments has always been an important goal to US Navy.
Because of the large quantity of steel used in ship construction
and repair, and the tremendous amount of money spent annually for
corrosion control, it is imperative that good protective coatings
are found to protect topside systems. To achieve this objective,
a long term study was conducted to evaluate the performance of
some aluminum pigmented coatings on carbon steel in various
marine environmental. An attempt is made to correlate the
results obtained from the field and laboratory tests. Several
coatings appear to be promising candidates for harsh marine usage
for surface combatants.
