| dc.description | Electroplating adalah proses pelapisan permukaan logam menggunakan media
penghantar cairan elektrolit dengan memberikan aliran listrik pada media tersebut.
Penelitian ini bertujuan untuk mengetahui pengaruh jarak throwing antara anoda
dan katoda pada proses electroplating ring plate terhadap tampilan fisik
(decorative), ketebalan lapisan dan ketahanan korosi. Dalam kegiatan ini proses
electroplating menggunakan variasi jarak antara anoda dan katoda sebesar 15 cm,
17,5 cm dan 20 cm.
Proses electroplating dilakukan dengan menggunakan dua pelapisan logam
yaitu nikel dan krom. Proses electroplating nikel dilakukan dengan menggunakan
arus 8 Ampere dan tegangan 2,3 Volt dengan waktu 30 menit, sedangkan pada
electroplating krom dilakukan dengan arus 25 Ampere dan tegangan 6,9 Volt
dengan waktu 30 detik.
Hasil penelitian menunjukkan disetiap segmen nilai ketebalan lapisan tertinggi
yaitu pada jarak anoda-katoda 17,5 cm dan nilai terendah terdapat pada jarak anodakatoda
20 cm. Pada jarak throwing anoda dan katoda pada jarak 15 cm, ketebalan
menurun dikarenkan ion-ion krom yang menempel pada permukaan spesimen
mempunyai sifat jenuh, sehingga dapat merusak ikatan lapisan spesimen yang
mengakibatkan merusak tampilan fisik, penurunan ketebalan dan ketahanan korosi
permukaan spesimen. Ketahanan korosi yang terjadi pada ring plate dengan variasi
jarak throwing anoda-katoda sebesar 17,5 cm dan 20 cm memiliki ketahanan korosi
yang sama yaitu sebesar 2% dari kedua variasi. | en_US |
| dc.description.abstract | Electroplating is the process of coating a metal surface using an electrolyte
liquid delivery medium by providing electricity to the media. This study aims to
determine the effect of the throwing distance between the anode and cathode on the
ring plate electroplating process on physical appearance (decorative), coating
thickness and corrosion resistance. In this activity the electroplating process uses
variations in the distance between the anode and cathode by 15 cm, 17.5 cm and 20
cm.
The electroplating process is carried out using two metal coatings namely
nickel and chrome. The nickel electroplating process is carried out using a current
of 8 Amperes and a voltage of 2.3 Volts with a time of 30 minutes, while the chrome
electroplating is carried out with a current of 25 Amperes and a voltage of 6.9 Volts
with a time of 30 seconds.
The results showed that in each segment the highest value of layer thickness
was at the anode-cathode distance of 17.5 cm and the lowest value was at the anodecathode
distance of 20 cm. At the throwing distance of the anode and cathode at a
distance of 15 cm, the thickness decreases because the chrome ions attached to the
surface of the specimen have saturated properties, so that it can damage the bonding
specimen layer which results in damaging physical appearance, decreased thickness
and corrosion resistance of the specimen surface. Corrosion resistance that occurs
in the ring plate with an anode-cathode throwing distance variation of 17.5 cm and
20 cm has the same corrosion resistance that is equal to 2% of the two variations | en_US |
