Electroplating Process

The electroplating method has the aim of producing a surface that has characteristics by the coating metal. The coating process requires a device that can place the ions from the coating material (anode) into the coated metal (cathode) through an electro-deposition process. Parameters such as temperature affect the electroplating process and greatly determine the coating result. The purpose of this study was to design the electroplating device, as well as to test the coating process using CuSO4 anode. The research method was carried out with an experimental approach through the manufacture of electroplating tools and coating testing of time variations of 20, 26, 32, 38, and 44 minutes and temperatures of 60, 65, 70, 75, and 80 oC. The results of the electroplating device design consist of frame components, plating and rinsing tubs, electrical systems, and cathode hanger. The coating results obtained the highest layer thickness 2.890 μm at a temperature of 80 oC for 40 minutes.

AbstractDye sensitized solar cells of the Graetzel type are usually fabricated with TiO2 covered with dye after its synthesis as one electrode. ZnO is, aside from TiO2, a promising alternative semiconducting material for solar energy conversion due to its enhanced surface area and a strong attachment of non-aggregated sensitizer dyes. We investigate ZnO/dye electrodes where the dye is already added during the electro-deposition process of the ZnO. We examine the influence of the dye species and the dye concentration on the surface morphology by means of atomic force and scanning electron microscopy imaging. The electrical properties of the films are characterized by means of current-voltage measurements. In order to study the integral properties of the charge carrier transport in the lateral direction of the film we characterized ZnO thin films electro-deposited across an insulating gap between two microstructured electrodes made of gold.

Proses pelapisan krom keras merupakan proses akhir atau tahap penyelesaian pada kebanyakan pembuatan komponen agar tidak cepat aus, seperti pada poros, pasak, ring piston, silinder, bearing dan crank shaf. Dalam bidang industri sifat mekanik yang banyak diperlukan pada logam yang dipergunakan adalah kemampuannya untuk tahan aus dan tahan korosi yang mana kita ketahui logam mempunyai reaksi yang sangat aktif terhadap perubahaan temperatur dan cuaca, maka perlu dilakukan pelapisan sehingga kemungkinan suatu bahan logam terkena korosi bisa dihambat. Bahan spesimen yang di gunakan adalah Baja St 60 (C 0.40%; Mn 7%; Si 0.28%; P+S 0.09%; Fe 98,53%) dengan variasi tegangan listrik: 4, 6, dan 8 volt, untuk variasi waktu elektroplating krom keras 30, 45, dan 60 menit. Pengujian yang dilakukan dengan pengukuran ketebalan lapisan menggunakan skala foto mikro dan menghitung ketebalan lapisan permukaan. Hasil penelitian menunjukkan bahwa semakin tinggi tegangan listrik yang digunakan dan semakin lama waktu proses pelapisan krom keras maka meningkat ketebalan lapisannya. Ketebalan lapisan permukaan yang paling tebal didapatkan pada tegangan 8 volt dengan waktu pelapisan 60 menit dengan ketebalan lapisannya sebesar 89,37 ?m, sedangkan ketebalan lapisan permukaan tipis didapat pada tegangan 4 volt dengan waktu pelapisan 30 menit ketebalan lapisannya sebesar 20,18 ?m. Jadi tegangan listrik dan waktu electroplating dapat mempengaruhi dan memberikan efek terhadap ketebalan lapisan yang terjadi pada Baja St.60. The hard chrome coating process is the final process or completion stage in most parts making so as not to wear out quickly, such as on the shaft, pegs, piston rings, cylinders, bearings and crank shafts. In the industrial field of mechanical properties that are much needed in the metal used is its ability to withstand wear and corrosion resistance which we know metals have a very active reaction to changes in temperature and weather, coating is necessary so that the possibility of a metal being corroded can be inhibited. The specimens used were Baja St 60 (C 0.40%; Mn 7%; Si 0.28%; P + S 0.09%; Fe 98.53%) with variations in electrical voltage: 4, 6 and 8 volts, for time variations hard chrome electroplating 30, 60 and 90 minutes. Tests carried out by measuring the thickness of the layer use a micro photo scale and calculate the thickness of the surface layer. The results showed that the higher the voltage used and the longer the coating process was hard chrome, the thickness of the layer increased. The thickest surface layer thickness was obtained at 8 volts with a coating time of 60 minutes with a layer thickness of 89.37 ?m, while the thickness of the thin surface layer was obtained at a voltage of 4 volts with a coating time of 30 minutes layer thickness of 20.18 ?m. So the electrical voltage and time of electroplating can affect and give effect to the thickness of the coating that occurs in Steel St.60

We have developed a simulation code which predicts the film thickness of the electro-deposition coating for automotive bodies. The time-dependent electro-potential distribution in the paint materials is predicted based on an electro-potential diffusion equation. As for descretization, we adopt the unstructured finite volume method. In order to verify the code accuracy, we have done a calculation for the electro-paint deposition experiment of a small box with 3 plates inside in it. The calculated results agreed with the test results very well not only qualitatively, but also quantitatively, especially in the range of 10 micron, which is included in the thickness criteria for automotive design. In addition, we applied the code to the real center pillar of an automobile. The analysis results mostly agreed with the results obtained from the experiment with the center pillar. This paper will describe the application case of this analysis code.

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.
