Proses elektroplating nikel dengan variasi jarak anoda katoda dan tegangan listrik pada baja ST-41

Electroplating process is a coating process where the deposition of a thin metal coating occurs on a coated surface using direct current and constant voltage. The process of finishing metal products uses Nickel as a coating that serves to improve the properties of the metal so that it resists corrosion and attach importance to the appearance of the metal surface. The metal coating process is carried out by electroplating technique with Nickel which occurs as an anode, and electrolyte uses in this process contained Nickel Sulphate. This study aims to determine the effect of distance variations and electrical pressure on layer thickness and adhesive strength. Anode Material coated with ST-41 Steel Plate with dimensions of 70 x 25 x 20 mm. While the cathode uses nickel (Ni) with dimensions of 10 x 20 x 20 mm. Cathode distance variations with anodes 5, 10, and 15 cm and electrical voltage variations of 3.5 Volts, 5 Volts, and 7.5 Volts. Bath time of 40 minutes and adhesion testing using the Posi Test AT-M Adhesion Tester.

Aluminum Material

Electroplating uses aluminum material, where it’s easy to obtain, lighter, and cheaper than other metals. The research goal was to determine the ability of the electric current to power aluminum (Al) coated with silver (Ag) by the electroplating method, to determine the effect of the magnitude of the electric current and the length of time the coating process took on the weight of Al coated with Ag and to determine the strength of the metal Al after tested using Brinnell test. The method used is to compare pure Al and pure Al coated with Ag by electroplating at different currents to determine the effect of the electroplating process. A Brinnell test was carried out to determine the hardness of the Al material after electroplating. The results are the amount of current that flows during the electroplating is directly proportional to the thickness of the electroplating layer attached to the Al surface. If the electroplating process uses a large current, the attached layer will look rough and not smooth, which also affects the material testing by using the Brinnell method. The Brinnell test proves that the hardness value of the Al material is directly proportional to the thickness of the layer.

Saat ini, banyak perangkat elektronik yang menggunakan baterai sebagai sumber dayanya seperti handphone dan laptop. Sebuah charger baterai yang bersumber AC (Alternating Current) memiliki sebuah penyearah AC ke DC (Direct Current). Keluaran penyearah AC-DC tidak sesuai untuk pengisian CC/CV (Constant Current/Constant Voltage), sehingga diperlukan buck converter untuk menghasilkan nilai yang diinginkan. Selain itu, penyearahan AC-DC membawa ripple yang dapat merusak baterai dan mempengaruhi rectification ratio (RR), sehingga memerlukan filter untuk mengurangi ripple dan meningkatkan rectification ratio. Percobaan dilakukan pada kondisi arus konstan atau CC 1,5A dan kondisi tegangan konstan atau CV 4,2V menggunakan variasi beban. Pada percobaan CC, diketahui bahwa peningkatan beban akan menyebabkan peningkatan duty cycle yang dibutuhkan. Pada uji coba CV, diperoleh hasil bahwa peningkatan beban menyebabkan pengurangan duty cycle yang dibutuhkan. Penggunaan filter pada kondisi CC dan CV dapat mengurangi ripple dan meningkatkan RR. Pada kondisi CC, ripple matematis, simulasi, dan uji coba secara berturut-turut berkurang 46,45%, 46,43%, dan 45,46%. RR matematis, simulasi, dan uji coba secara berturut-turut meningkat 18,17%, 18,17%, dan 21,59%. Pada kondisi CV, ripple matematis, simulasi, dan uji coba secara berturut-turut berkurang 46,44%, 46,6%, dan 48,78%. RR matematis, simulasi, dan uji coba secara berturut-turut meningkat 18,17%, 18,17%, dan 20,99%. Pengisian Li-ion 3Ah memakan waktu 4 jam 58 detik. Dimana pengisian CC selama 32 menit 10 detik dan pengisian CV selama 3 jam 28 menit 48 detik. Pada pengisian CC duty cycle meningkat saat terjadinya peningkatan tegangan baterai. Sedangkan pada pengisian CV, duty cycle menurun saat berkurangnya arus pengisian.

Chrome Electroplating

Electroplating is a process of settling substances (metal ions) on the electrodes (cathodes) using electrolysis. The occurrence of a precipitate in this process is due to the presence of electrically charged ions moving from an electrode through the electrolyte, the result of the electrolyte will seal on another electrode (cathode). During the process of deposition/deposit takes place a chemical reaction occurs at the electrode and electrolyte both reduction in a certain direction permanently, therefore it requires direct current and a constant voltage. Metal coatings commonly used are copper, nickel, chromium, and others. Electroplating is basically to coat the metal to make it look more attractive and protected from corrosion, and can increase the product's resistance to friction. The purpose of this study was to determine the effect of stirrer rpm variations on the thickness and thickness of the A36 steel layer in the decorative nickel-chrome electroplating process. 4 specimens in this study were 30x30x2 (mm). Nickel and chromium coatings have variations in the speed of 72, 102, 132, and 162 (rpm) with a time immersion of 22 minutes and with a temperature of 55-60 ° C. The results of this electroplating process were tested by Vickers's hardness test and observation of microstructure results. The results showed that the faster the rpm, the more hardness was obtained which increased and the thickness of the layer increased. The highest hardness and thickness values are found at a rotational speed of 132 rpm. With a hardness value of 77.5 VHN and a thickness value of 4.55 µm (Nickel) and 13.76 µm (Chrome).
