Abstract
Telah dilakukan proses pelapisan komposit Ni-TiAlN untuk mengkaji pengaruh variasi konsentrasi Sodium Dodecyl Sulfate (SDS) terhadap morfologi permukaan, sistem kristal dan kekerasan lapisan komposit Ni-TiAlN yang telah terbentuk. Proses pelapisan menggunakan metode elektrodeposisi dengan arus 3mA, selama 15 menit. Lapisan komposit ini terbentuk pada substrat Tungsten Karbida dengan komposisi larutan elektrolit yang terdiri dari 2 gr/l AlN; 2 gr/l TiN; 0,49 mol/L H3BO3; 0,17 M NiCl26H2O; 0,38 M NiSO46H2O dan SDS. Variasi konsentrasi SDS yang digunakan yaitu 0,2 gr/l; 0,4 g/l dan 0,6 g/l. Berdasarkan pengujian karakterisasi Scanning Electron Microscopy (SEM) dan Energy Dispersive Spectroscopy (EDS) variasi konsentrasi 0,4 gr/l membentuk aglomerasi lebih sedikit dan komposisi Ni-TiAlN 39,83% dibandingkan SDS 0,2gr/l dan 0,6 gr/l. Berdasarkan uji X-Ray Diffraction (XRD) dan uji keras terjadinya peningkatan ukuran kristal dan diikuti pula peningkatan nilai kekerasan lapisan disetiap kenaikan variasi konsentrasi SDS. An experiment has been done to deposit a composite coating of Ni-TiAlN, the expeeriment has coducted to study the effect of concentration variation of SDS on surface morphology, crystal structure and hardness of composite Ni-TiAlN layers. Coating process is used electrodeposition method with current 3mA, for 15 minutes. This composite layer is formed on a Tungsten Carbide substrate with an electrolyte solution composition comprising 2 gr/l AlN; 2 g/l TiN; 0.49 mol/l H3BO3; 0.17 M NiCl2.6H2O; 0.38 M NiSO46H2O and SDS. SDS concentration variations used were 0.2 gr/l; 0.4 gr/l and 0.6 gr/l. Based on the characterization test of Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS), less aglomeration was formed on the surface coating at SDS concentration of 0,4 gr/l formed of less aglomeration and Ni-TiAlN composition 39,83% than SDS 0,2gr/L and 0,6 gr/l. Based on X-Ray Diffraction (XRD) test and hardness test of crystal size increase and followed by increase of layer hardness value in every increase of SDS concentration variation.
