Abstract

ABSTRAK Sebagai logam ringan dengan rasio kekuatan terhadap berat yang tinggi, magnesium banyak digunakan dalam industri manufaktur, tetapi ketahanan korosinya yang rendah memerlukan perlakuan anodisasi guna membentuk lapisan pelindung oksida. Oleh karena itu, penelitian menerapkan proses batch anodisasi magnesium menggunakan metode barreling untuk meningkatkan keseragaman lapisan oksida yang terbentuk. Penelitian dilakukan secara eksperimental menggunakan larutan elektrolit NaOH 1 M sebanyak 350 mL dengan parameter arus 0,5 A, 1 A, dan 2 A, serta putaran barrel 0 rpm, 50 rpm, dan 100 rpm selama 20 menit setiap proses. Pengujian yang dilakukan meliputi perubahan massa menggunakan timbangan digital, kekasaran permukaan menggunakan Surfcorder SE 1200, ketebalan lapisan menggunakan Coating Thickness Gauge AMT15, serta analisis morfologi permukaan menggunakan Scanning Electron Microscope (SEM). Hasil penelitian menunjukkan bahwa metode barreling berhasil diterapkan pada proses batch anodisasi magnesium, menghasilkan lapisan pelindung yang merata secara visual pada seluruh spesimen. Kuat arus rendah efektif menekan pelarutan massa sekaligus mengoptimalkan ketebalan lapisan oksida. Rotasi barrel memastikan distribusi arus dan aliran elektrolit merata pada seluruh spesimen untuk menghasilkan tingkat kekasaran permukaan yang rendah dan ketebalan lapisan yang seragam. Kata Kunci : Magnesium, Batch Anodisasi, Metode Barreling, Lapisan Oksida. ***** ABSTRACT As a lightweight metal with a high strength-to-weight ratio, magnesium is widely used in the manufacturing industry; however, its low corrosion resistance necessitates an anodization surface treatment to form a protective oxide layer. Therefore, this study applies a batch magnesium anodization process using the barreling method to improve the uniformity of the formed oxide layer. The research was conducted experimentally using a 350 mL electrolyte solution of 1 M NaOH with current parameters of 0.5 A, 1 A, and 2 A, as well as barrel rotation speeds of 0 rpm, 50 rpm, and 100 rpm for 20 minutes per process. The performed evaluations included mass change analysis using a digital scale, surface roughness measurement using a Surfcorder SE 1200, coating thickness testing using an AMT15 Coating Thickness Gauge, and surface morphology analysis using a Scanning Electron Microscope (SEM). The results indicated that the barreling method was successfully implemented in the batch magnesium anodization process, producing a visually uniform protective layer across all specimens. Low current density effectively suppressed mass dissolution while optimizing the thickness of the oxide layer. Furthermore, the barrel rotation ensured even current distribution and electrolyte flow across all specimens, resulting in low surface roughness and uniform coating thickness. Keywords : Magnesium, Batch Anodizing, Barreling Method, Oxide Coating.
