Abstract :
Corrosion is one of the problems that is often found in industry, especially
in materials containing iron or carbon steel. And How to Stop Corrosion in
Materials by Using Materials with Zinc Coating. This zinc plating layer is an
alternative for the automotive industry because in addition to the cost of materials
that are cheap, easy, and very easy in the process. This research was conducted to
find the ideal current and time used during the plating process, because in every
industry the most frequent problems are the thickness that coats the material and
the corrosion rate of the material that causes the material to become damaged or
no good. This study uses ASTM A36 carbon steeland zinc as a coating. The
research was carried out on a tank containing various kinds of chemical liquids
and using electric current as conductivity for the coating media. Analysis using
layer thickness measurement using dial thickness gauge measuring instrument and
weight loss method. The results obtained from searching the current and the ideal
time using a current of 900 A and a time of 60 minutes is 0.015 mm or 15 ?m thick
and the SST test (Salt Spray Test) at 96 hoursNo White Rust and 144 Hours No
Red Rust.
