PENGARUH JENIS MEDIA KOROSIF TERHADAP LAJU KOROSI BESI COR KELABU
Abstract: Corrosion is one of
dangerous-phenomenon which can generate a lot of loss. Grey cast iron is the
most useful material by a human being to various industrial need and
engineering. This use is triggered from advantage its use. The use of grey cast iron in various area causes grey cast iron has to deal with
various environment. This research aim
to determine corrosion rate of grey cast
iron in corrosive media of the sea,
condensation of NaCl 5 % concentration,
and calcify condensation in concentration 5 %. Method used by taking data from
appliance echem corrosion test. Result got to be analysed by softcorr 342 DC
corrosion . Result of data analysis indicated that at corrosive media type sea smallest corrosion rate was 2,194 mpy and
biggest 17,279 mpy. The smallest Corrosion rate at corrosive media of Nacl was 2,663 mpy and biggest 5,800 mpy.
While corrosion rate at corrosive media
of calcify condensation was 0,003
until 12,992 mpy. Corrosion type at the
sea and salt condensation corrosive media was pitting corrosion.
