Abstract
Baja menjadi sangat mudah terkorosi ketika berada
dalam lingkungan yang korosif. Coating merupakan salah satu
metode proteksi korosi untuk baja. Coating menggunakan metode
hot dip galfan dapat dijadikan solusi untuk proteksi korosi pada
baja. Kualitas hasil coating ditentukan oleh beberapa factor
diantaranya adalah sifat adhesive, ketebalan dan ketahanan
korosi, dimana ketiganya dipengaruhi oleh waktu pencelupan.
Penelitian ini menganalisis pengaruh waktu celup terhadap sifat
adhesive, ketebalan, dan ketahanan korosi lapisan. Waktu celup
yang digunakan adalah 1,5,9, dan 13 meni pada temperatur
450oC. Pada penelitian ini telah dilakukan pengujian SEM,
Metallography, XRD, Thickness Test, Adhesive Test, dan Weight
loss. Berdasarkan hasil pengujian, nilai ketebalan maksimum
adalah 288.9µm, nilai kekuatan adhesive maksimum adalah 8,05
Mpa, dan nilai ketahanan korosi yang paling optimum adalah
0.0229mmpy. Nilai ketebalan dan sifat adhesive yang dihasilkan
dipengaruhi oleh itermetallic layer yang terbentuk. Waktu
pencelupan 1 menit memiliki struktur mikro intermetallic layer
yang berbeda dibandingkan dengan variable waktu celup yang
lainnya. Senyawa intermetallic yang terbentuk adalah Fe2Al5.

Steel is easily corroded in a corrosive environtment.
Coating is a method of corrosion protection for a steel. Hot dip
galfan coating is able to be a solution for corrosion protection for
a steel. The quality coating is determined by several factors, there
are adhesive properties, thickness, and corrosion resistance of
coating, all of whom are affected by immersion time. This
research analyzed the effect of immersion time to the adhesive
properties , thickness , and corrosion resistance of coating. The
immersion time that used are 1,5,9 , and 13 minutes at 450oC .
This research has been evaluated by several test, there are SEM ,
Metallography , XRD , Thickness Test , Adhesive Test , and
Weight loss. Based on the test results , the maximum thickness
value is 288.9μm , maximum adhesive strength value is 8.05 Mpa
, the most excellent corrosion resistance value is 0.0229 mmpy.
The value of the thickness and properties of the resulting adhesive
layer is affected by itermetallic formed . The immersion time of 1
minute has the microstructure intermetallic layer that is different
than the other variable immersion time . Intermetallic compounds
formed is Fe2Al5 .
