| description | Cathodic protection in the sacrificial
system is essentially a controlled
electrochemical cell; corrosion on the
protected structure is shifted to the
anode. When the anode material is
coupled to steel, they behave anodically
and discharge current.In this work,
magnesium used as sacrificial anode for
the protection of carbon steel rod that
buried in soil with resistance of 1000,
1400, 1800, and 2200Ω/cm that simulate
wide range of resistance of Iraqi
soil.Potential distribution in different
positions between sacrificial anode and
the protected structure was measured
with respect to copper - copper sulfate
electrode, showing that the conditions
for the sacrificial anode for the
protection of carbon steel rod and
simulate with contours.The result show
that the increasing of soil resistivity is
reduces anode life and impairs its
performance. In addition, the changing
of sacrificial anode is important because
it consumed therefore, it is important to
optimize the distance of sacrificial anode
from protected structure according to
soil resistivity so that
avoiding the polarization that causes
high consumption rate of anode. |
