Abstract
Dalam tulisan ini, dilakukan pembentukan lapisan komposit Ni-TiN-AlN untuk mengkaji pengaruh variasi rapat arus pulsa terhadap morfologi permukaan dan komposisi lapisan. Proses pelapisan dilakukan dengan metode elektrodeposisi. Lapisan komposit Ni-TiN-AlN terbentuk pada substrat Tungsten Karbida (WC) dengan komposisi larutan elektrolit yang terdiri dari 0.17 M NiCl2.6H2O, 0.38 M NiSO4.6H2O, 0.49 M H3BO3, 0.6 g/l Sodium Dodecyl Sulfate (SDS), partikel serbuk penguat TiN sebesar 6 gr/l dan serbuk AlN sebesar 10 g/l. Elektrodeposisi pada substrat dilakukan selama 30 menit dan variasi rapat arus yang digunakan sebesar 0.15 mA/mm2, 0.25 mA/mm2, dan 0.35 mA/mm2. Lapisan komposit Ni-TiN-AlN dikarakterisasi dengan menggunakan SEM-EDS (Scanning Electron Microscopy-Energy Dispersive Spectroscopy), Difraksi Sinar-X (XRD), dan Uji Keras (Vickers). Hasil menunjukkan bahwa morfologi permukaan dan komposisi lapisan komposit Ni-TiN-AlN dipengaruhi oleh rapat arus yang digunakan. Kata-kata kunci: Elektrodeposisi, Rapat Arus, Lapisan Komposit Ni-TiN-AlN, Morfologi, Komposisi. ***** In this paper, the formation of a Ni-TiN-AlN composite coating layer is carried out to study the effect of variations in pulse current density on surface morphology and coating composition. The coating process is carried out using the electrodeposition method. The Ni-TiN-AlN composite layer was formed on a Tungsten Carbide (WC) substrate with an electrolyte solution composition consisting of 0.17 M NiCl2.6H2O, 0.38 M NiSO4.6H2O, 0.49 M H3BO3, 0.6 g/l Sodium Dodecyl Sulfate (SDS), particles TiN strengthening powder of 6 gr/l and AlN powder of 10 g/l. Electrodeposition on the substrate was carried out for 30 minutes and variations in current density used were 0.15 mA/mm2, 0.25 mA/mm2, and 0.35 mA/mm2. The Ni-TiN-AlN composite layer was characterized using SEM-EDS (Scanning Electron Microscopy-Energy Dispersive Spectroscopy), X-Ray Diffraction (XRD), and Hardness Test (Vickers). The results show that the surface morphology and composition of the Ni-TiN-AlN composite layer are influenced by the current density used. Keywords: Electrodeposition, Current Density, Ni-TiN-AlN Composite Coating, Morphology, Composition.
