PENGARUH KADAR KARBON DALAM BAJA PADA PROSES PELAPISAN ALUMINIUM CELUP PANAS
Abstract: Carbon steel is
widely used as a component of engineering work in high temperature conditions.
During the application decreases of oxidation resistance drastically. A steel
coating is very needed to increase an oxidation resistance. One technique is
inexpensive and used to be coating for large components are hot dip coating.
This experiment aimed to determine the
effect of carbon content in steel AISI 1020, AISI 1045 and AISI 1090 against
hot dip aluminium coating on hot dip
aluminium coating process and to study the influence of immersion time in the
tub aluminium molten steel on the growth
of intermetallic layer. Immersion times used were 4, 9, and 16 seconds with a
temperature of 700 °C. Volume composition used for each solution is 100 ml flux
with three variations, namely Y1 flux ( 1.5 g KF, NaF 1.5 g, 8.5 g Borax , and
2.5 g of acetic acid ), Y2 ( 2.0 KF g, 2.0 g NaF, 9.5 g Borax, and 3.0 acetic
acid ) and Y3 ( 2.5 g of KF, 2.5 g NaF, 10 g Borax, 3.5 g acetic acid ). Then
do the impact test , SEM , OM and XRD. For the most thick aluminium layer was
AISI 1020 steel with immersion time of 4 seconds is 0.118 mm and Fe - Al
intermetallic layer ( FeAl3+Fe2Al5 ) is the thickest on AISI 1045 steel with
immersion time of 9 seconds. Energy values were greatest impact on AISI 1020
steel is 187.2 J, means less carbon content of the energy generated greater
impact.
