Many engineered structures have a limited life span and are
deteriorated because of the loss of material properties,
exposure to severe environments or increases in service loads.
Carbon steel is one of the most widely used materials in the
ship and offshore structure industry. Corrosion and corrosion-
related problems are considered to be the most important factors
leading to age-related structural degradation of ships and many
other types of steel structures. Corrosion considered as the most
important factor leads to the structural degradation of ships and
other types of steel structures intended for work in the marine
environment. Corrosion of carbon steel in marine environment
becomes serious due to the highly corrosive nature of seawater
with high salinity and microorganisms. Various organic and
inorganic coatings are used to protect metallic materials
particularly steel against corrosion occurrence. The most used
are the polymeric protective coatings. The nanostructured
TiO2 polymer coating is able to offer higher protection to steel
against corrosion and performed relatively better than other
polymer coatings. The aim of the paper is to show the role of
TiO2 nanoparticles in the enhancement of protective coatings
and the lifespan of marine structures. The novelty of this research
consist of the comparative assessment of corrosion resistance of
different types of surfaces: E32 low alloy steel without protective
coating, E32 coated with polymeric primer and E32 steel coated
with polymeric primer mixed with TiO 2 nanoparticles. All samples
were subjected to corrosion in sea water collected from the Black
Sea, Năvodari Oil Terminal. The corrosion properties have been
studied by electrochemical methods. The purpose is to improve
the protection capabilities of polymeric coatings by adding
dispersed inert ceramic nanoparticles as titanium oxide with an
average diameter of 200 nanometers.
