The majority of naval ships
are constructed of mild steel. Corrosion is a major concern in a maritime
environment. This particular type of material degradation has recently received
more attention by the marine industry. The present work aims to investigate the
effect of recent coatings used in marine ship surfaces for preventing
corrosion. Experiments were performed according to standard tests to evaluate
and measure the coating adhesion to steel and to measure the corrosion wear
rate if any for three types of coatings. An accelerated corrosion test was
conducted to duplicate in the laboratory the field corrosion performance of a
product. The results indicate that all tested types of paint have resulted in a
reduction in the corrosion rate compared with the uncoated steel. A minimum
corrosion rate of 0.8 mm/year for the coat “Hempadur 52,140” was obtained
compared to 2.1 mm/year for the uncoated steel. A microscopic examination of
the corroded steel surfaces was conducted which prevailed pitting behavior with
different degree. The minimum corroded surface exhibited few pitting attack in
comparison to other specimens. Although the pitting attack of the surface layer
(paint), one can drive a conclusion that sample surface without coating is
aggressively attacked by pits.
