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 %.

Abstract

ANALISA KERUSAKAN PADA ATAP ZINCOATING DI LINGKUNGAN ATMOSFER INDUSTRI.Telah terjadi kerusakan pada atap salah satu pabrik di Kawasan Industri di Bekasi. Atap tersebut telahdilindungi oleh lapisan zinccoating. Namun, setelah pemakaian selama 16 bulan, atap tersebut telahmengalami kerusakan. Bentuk kerusakannya adalah deposit berwarna kecoklatan tebal dan tipis yangmenempel pada atap tersebut. Pada tulisan ini, analisa kerusakan yang dilakukan antara lain pemeriksaanvisual, SEM-EDAX, metalografi, uji kerapatan deposit, dan analisa laju korosi. Hasil menunjukkan bahwawarna kecoklatan yang menempel pada atap tersebut disebabkan karena adanya deposit besi oksida dariudara. Adanya deposit tersebut mengakibatkan terjadi korosi galvanik antara deposit besi oksida denganzinccoating. Laju korosi terbesar ditemukan pada atap dengan deposit warna kecoklatan tebal. AbstractThere has been damage to the roof of a factory in Industrial Area in Bekasi. The roof has been coated by azincoating. However, after 16 months of usage, the roof has been damaged. The form of damage is thick andthin brownish deposits that stick on the roof. In this paper, the analysis of the damage include visualinspection, SEM-EDAX, metallography, test of deposit density, and analysis of the corrosion rate. Theresults showed that the color brown that sticks to the roof caused by the deposit of iron oxide from the air.The existence of deposits resulted in galvanic corrosion between iron oxide deposit and zincoating layers.Greatest corrosion rate was found in the roof with a thick brownish deposits.
