KOMPARASI EFISIENSI MATERIAL BAJA KARBON St 37, BAJA KARBON St 41 DAN BAJA KARBON St 60 TERHADAP LAJU KOROSI DI MEDIA AIR MUARA SUNGAI (PAYAU) DENGAN METODE ELEKTROKIMIA
Abstract: Mouth of the river
is the meeting place of river water and sea water . water estuaries (brackish
water) has asodium chloride content of between 1% -2.5 whether it's from
natural sources around the surrounding river water or a mixture of sea water .
many construction or structure that is attached to the mouth of the river
environment made of metal materials, especially carbon steel.
the use of steel in building
structures in estuaries susceptible
to corrosion due
to environmental water
containing chemical elements
that are corrosive. Factors affecting
corrosion such as
temperature, acidity (pH),
salinity (NaCl), the
levels of chloride (Cl),
the levels of sulfate
(SO) as well as dissolved oxygen, causing easily corroded carbon steel. This study aims to determine the
Comparative Efficiency of Steel St 37, St 41 Steel and Steel st 60 on the rate
of corrosion in aqueous media estuaries
with tool Potensiostat methods. This
research is an experimental laboratory
to design the post-test group design. From the results obtained data show the
results of corrosion rate measurements made
in this study that
the greatest rate of corrosion occurring on the steel material St 37 is 29.527 mpy, St
41 steel was 27.548 mpy, and steel St 60
is 24,493 mpy. The results showed
that the corrosion rate of steel
st 37 has a very large corrosion rate in comparison steel and carbon steel st
41 high st 60. From the observation in
micro on the trid specimen
three is corrosion that resembles a uniform or evenly corrosion.
A form of corrosion
that results in a uniform attack on the
entire surface of the metal.
