Abstract
Telah dilakukan pembentukan lapisan tipis komposit elektrodeposisi Ni-TiAlN pada batang tungsten karbida. Sejumlah 6 gr/liter masing-masing serbuk TiN dan AlN ditambahkan kedalam larutan elektrolit yang terdiri dari 0.38 M Ni2SO4.6H2O, 0.17 M NiCl2.6H2O,dan 0.49 M H3BO3. Percobaan dilakukan dengan sistem elektrodeposisi sederhana yang terdiri dari rangkaian power supply, gelas kimia, kabel, resistor, larutan elektrolit dan elektroda. Elektrodeposisi dilakukan pada arus sebesar 2, 3 dan 4 mA selama 25 menit. Hasil penelitian menunjukkan sampel pada arus 4 ma memiliki struktur kristal FCC , morfologi paling halus, komposisi nikel paling banyak dan laju korosi paling kecil. Has been done the formation a thin layer of composite elektrodeposisi Ni-tungsten carbide rods on TiAlN.. Amount of 6 gr/liter of TiN and AlN powders were added into the electrolyte solution that consists of 0.38 M Ni2SO4.6H2O, 0.17 M NiCl2.6H2O, 0.49 M H3BO3 and 0,06 gr/l Sodium Dodecyl Sulfat (SDS). The experiment was performed with autonomous electrodeposition system because the device completed with potensiostat is expensive. Electrodeposiyon system is consist of power suplly, cable, resistor, electrolyte solution, and electrode. Electrodeposition was do in current of 3mA for about 25 minutes. The results showed the samples on a current of 4 ma have a FCC crystal structure, most subtle morphology, most nickel composition and most small corrosion rate
