| dc.description.abstract | The life time of metallic materials used in naval transport industry is
influenced by their corrosion resistance. For utilization in shipbuilding and offshore
construction, metallic materials need to be covered with protective coatings,
especially, or different anti-corrosion protection methods need to be used. During
the last decades a series of inorganic and organic coatings was developed. Among
inorganic coatings, the most used ones are the galvanizing treatments. This paper
presents a comparative investigation regarding the corrosion resistance of uncoated
low alloy steel and galvanizing steel. Both samples have been subjected to corrosion
in sea water harvested from the Black Sea, Mangalia harbor. The electrochemical
assays were: open circuit potential (OCP), linear polarization resistance (Rp),
potentiodynamic polarization (PD) and cyclic voltammetry. The results obtained by
in situ determination were confirmed by optical microscopy. The results revealed an
improved corrosion resistance of galvanized steel in natural sea water in
comparison with low alloy steel. | ro_RO |
