Abstract

Telah dilakuka n penelitian tentang pembuatan lapisan paduan Ni-Mo  yang akan digunakan sebagai lapisan bond coat untuk lapisan tahan temperatur tinggi (TBC). Penelitian dilakukan dengan menggunakan bahan dasar plat nikel 99% yang diroll dan dibentuk sampel berukuran 25 x 50 x 2 mm. Sampel kemudian diberi lapisan dengan  cara elektroplating  menggunakan  larutan  yang  terdiri dari NiSO4 , Na2MoO4 ,  C8H8O7. Komposisi larutan divarisikan menjadi 5 jenis larutan dengan perbandingan; I.  0,1 : 0,1: 0,1 mol, II. 0,075 : 0,125 : 0,1 mol, III. 0,050 : 0,100 ,0,1 mol, IV. 0,025 : 0,125: 0,1 moll dan V. 0,001 : 0,2 : 0,1 mol. Proses dilakukan pada suhu ruang dengan rapt arus 0,1 A/dm2. Dari hasil percobaan diperoleh bahwa larutan III menghasilkan lapisan dengan kadar Mo terbaik yaitu 21,19%. AbstractThere has been done the experiment about electro deposition Ni-Mo alloy as a bond coat layer for high temperature resistance coating, known as Thermal barrier coating (TBC). The sample is made from Nickel 99%. Roll process was done to thinning the samples and then cut the material into 25 x 50 x 2 mm shape. Electroplating process was done on the surface of materials by mixed NiSO4, Na2MoO4 and C8H8O7 for the solution. Electroplating process was carried out at 0,1-0,6 A/dm2 at room temperature. Composition of the solution was varied within I. 0,1 : 0,1: 0,1 mol, II. 0,075 : 0,125 : 0,1 mol, III. 0,050 : 0,100 , 0,1 mol, IV. 0,025 : 0,125: 0,1 moll and V. 0,001 : 0,2 : 0,1 mol. The best Mo content from the experiment is NiMo coating from solution III, it was 21,19 %.
