Abstract

Telah dilakukan penelitian pembentukan lapisan komposit Ni-TiN-AlN/Si3N4 untuk mengkaji pengaruh temperatur terhadap morfologi lapisan. Proses pelapisan menggunakan metode elektrodeposisi dengan arus sebesar 5 mA selama 15 menit. Lapisan komposit ini terbentuk pada substrat tungsten karbida dengan komposisi larutan elektrolit yang terdiri dari 6 g/L AlN, 6 g/L TiN, 40 g/L H3BO3, 0.6 g/L Si3N4, 0.17 M NiCl2.6H2O, 0.38 M NiSO4.6H2O dan 0,6 g/L Sodium Dodecyl Sulfate. Variasi temperatur yang digunakan 35°C, 40°C dan 45°C. Penelitian ini menggunakan Karakterisasi Scanning Electron Microscopy (SEM) yang menunjukan bahwa semakin besar variasi temperatur maka morfologi permukaan lapisan komposit Ni-TiN-AlN/Si3N4 yang terbentuk semakin halus dan lebih berpori, Energy Dispersisive Spectroscopy (EDS) menunjukan bahwa semakin meningkatnya suhu maka semakin meningkatnya komposisi massa dan atomik unsur. Berdasarkan hasil karakterisasi X-Ray Diffraction (XRD) semakin kecil ukuran kristal seiring meningkatnya temperatur dan uji keras Vickers kekerasan tertinggi terdapat pada temperatur 45C. Research on the formation of Ni-TiN-AlN/Si3N4composite layers has been done to study the effect of temperature on the morphology of the layers. The coating process uses the electrodeposition method with a current of 5 mA for 15 minutes. Composite layer is formed on a tungsten carbide substrate with an electrolyte solution composition consisting of 6 g/L AlN, 6 g/L TiN, 40 g/L H3BO3, 0.6 g/L Si3N4, 0.17 M NiCl2.6H2O, 0.38 M NiSO4.6H2O and 0,6 g/L Sodium Dodecyl Sulfate. The temperature variations used are 35°C, 40°C and 45°C. The results of the Scanning Electron Microscopy (SEM) characterization process show that an increase in temperature makes the surface morphology of the Ni-TiN-AlN/Si3N4composite layer formed is smoother and more porous. The results of the Energy Dispersisive Spectroscopy (EDS) characterization process show that an increase in temperature increases the composition of the mass and atomic elements. The results of the X-Ray Diffraction (XRD) characterization process show that an decrease in crystal size with increasing temperature and the highest hardness in the Vickers characterization process at temperature 45 °C.
