Description
Assessment of silicon oil as natural inhibitor on brass
in 1 M H2SO4 acid solution has been studied using
linear potentiodynamic polarization and gravimetric
method in the inhibited concentration variation
between 2% to 10% range. Tafel extrapolation
techniques were used to obtain corrosion potential
(Ecorr) and corrosion current density (Icorr). From
all indication, the inhibitor is of mixed type. The
adsorption behavior occurs on the surface of brass
due to the presence of the absorbed complex atom
from the oil. The calculated portion of the surface
covered from the corrosion process follows Langmuir
adsorption Isotherm.
