Abstract

Sejalan dengan perkembangan industri logam di Indonesia yang saat ini maju dengan sangat pesat, termasuk berbagai pendukungnya. Kita lihat setiap harinya dari kebutuhan rumah tangga, automotif, dan elektronika serta lainnya, Ielah mengalami proses finishing logam yang salah satunya adalah lapis listrik (electroplating). Lapis listrik khususnya pelapisan chrom dekoratif yang mempunyai fungsi antara lain: memperbaiki penampilan, memberikan perlindungan terhadap korosi, dan tahan terhadap goresan atau gesekan, sehingga pelapisan chrom dekoratif ini banyak sekali digunakan. Pelapisan logam dengan elektroplating dalam penelitian ini menggunakan teknik pelapisan dasar chrom yang sangat tergantung pada pelapisan dasar (dekoratif), yang mana untuk lapis dasar menggunakan tembaga dan nikel, dan baru pada lapis terakhir menggunakan chrom. Benda kerja dalam proses pelapisan ini menggunakan plat baja. Parameter dalam penelitian ini menggunakan variasi tegangan (voltase) 1,2,3, .. 9,10,12,16,20,24, dan 28 volt dengan arus, waktu, dan temperatur larutan elektrolit tiap pelapisan di jaga konstan. Hasil yang didapat lalu dianalisa secara statistik dengan bantuan software Minitab. Dari hasil penelitian ini, disimpulkan bahwa pengaruh perubahan voltase dengan perbedaan jarak antara anoda atau logam pelapis (elektroda bermuatan positif) dan katoda atau specimen uji (Elektroda bermuatan negatiff) dalam pelapisan Chrom dekoratif sangat berpengaruh terhadap ketebalan pelapisan permukaan specimen yang dilapis. Dari hasil penelitian yang didapatkan, dipilih kriteria ketebalan lapisan chrom dekoratif yang optimal (mengkilap) yaitu terjadi pada voltase 12V, dengan jarak antara anoda-katoda 295 mm dan tebal lapisan mencapai 19 pm

In line with the development of the metal industry in Indonesia which is currently progressing very rapidly, including its various supporters. We see every day from household needs, automotive, and electronics and others, Iela has undergone a metal finishing process, one of which is electroplating. Electroplating, especially decorative chrome plating, has functions including: improving appearance, providing protection against corrosion, and resistance to scratches or friction, so that this decorative chrome plating is widely used. Metal plating with electroplating in this study uses a chrome base coating technique that is highly dependent on the base coating (decorative), which for the base layer uses copper and nickel, and only for the final layer uses chrome. The workpiece in this coating process uses a steel plate. The parameters in this study use variations in voltage (voltage) 1, 2, 3, .. 9, 10, 12, 16, 20, 24, and 28 volts with the current, time, and temperature of the electrolyte solution for each coating kept constant. The results obtained were then analyzed statistically with the help of Minitab software. From the results of this study, it was concluded that the effect of voltage changes with differences in distance between the anode or coating metal (positively charged electrode) and the cathode or test specimen (negatively charged electrode) in decorative chrome plating greatly affects the thickness of the coating on the surface of the coated specimen. From the research results obtained, the criteria for the optimal thickness of the decorative chrome layer (shiny) were selected, which occurs at a voltage of 12V, with a distance between the anode and cathode of 295 mm and a layer thickness of 19 pm
