Pengaruh Kuat Arus, Jarak, dan Waktu terhadap Laju Korosi Baja SS400 Berlapis Nikel dengan Proses Electroplating
Abstract
Low carbon steel is one type of metal that is often used in the industrial world. However, they
often experience losses due to the high level of damage due to corrosion. One of the efforts to
control corrosion can be done by metal coating, namely by electroplating. The electroplating
process is carried out by coating the surface of low carbon steel with nickel plating metal, so
that the surface hardness value increases. Factors that affect the electroplating results are the
current strength, distance and time variations.The purpose of this study was to determine the
effect of current strength, distance and time on the corrosion rate of SS400 steel with a nickelplated
electroplating process. This research was conducted at the Materials Testing
Laboratory, Department of Mechanical Engineering, Faculty of Engineering, University of
Jember which was carried out from July to November 2022. The results obtained in this study
were that the lowest corrosion rate after the specimen was coated with nickel coating with
electroplating occurred in specimen 8 with a time variable of 45 minutes, a current strength of
3A and a distance of 5 cm, namely 1.01 mpy and the highest corrosion rate occurred in
specimen 1 with a time 15 minutes, a current of 1A and a distance of 5 cm is 5.98 mpy. The
longer the time, the higher the current strength, and the closer the distance between the
electrodes used in the electroplating process, the corrosion rate will decrease.
