abstract = "There has been a recent increase in both the production and
consumption of ethanol due to the numerous environmental
advantages that it offers, such as the fact that it can be
produced from a variety of renewable materials, for instance corn
and cellulose, or it can be obtained from sugarcane bagasse and
biomass (2nd and 3rd generation ethanol). The result of this is
that nowadays ethanol is widely seen as the dominant biofuel or as
a blend component in gasoline or pure fuel - in many countries.
However, one disadvantage of the use of ethanol is the high
corrosive behavior that occurs when its hygroscopic properties are
exposed to a large number of materials. Xiaoyuan Lou and Preet
Singh showed that the increase of water concentration in ethanol
induces pitting and metal loss. Diamond-Like Carbon (DLC) films
may be a solution to this problem due to the fact that they can be
deposited inside tubes, offer good protection levels against
corrosion, and reduce the friction coefficient and wear. This
paper shows the tribocorrosion and corrosion studies of DLC films
deposited on stainless steel grade 304 (SS304) substrates in order
to gauge its appropriateness usage in the construction of
pipelines and fuel storage tanks. The surface morphology was
analyzed before and after 14 days of immersion. The
tribocorrosion, friction coefficient, and wear rate were studied
in ethanol to see the effects of water concentration. The films
showed good adherence to the substrates. Corrosion and
tribocorrosion results showed that for bare Stainless Steel 304
the increase of the water content increases the corrosion and the
friction coefficient. DLC coated samples presented few points of
delamination, and the friction coefficient and open circuit
potentials were very low compared with the bare sample which was
water concentration independent.",
