Abstract

Aluminium seri 6061 merupakan unsur paduan utama Al-Mg-Si. Dalam kehidupan sehari-hari penggunaan aluminium sangat banyak termasuk seri tersebut. Mulai konsumsi sesuai kebutuhan untuk berbagai bidang. Aluminium memiliki sifat mudah terbentuk korosi yang disebabkan oleh udara maupun air. Semakin rendah nilai tingkat korosi maka akan semakin baik. Berbagai macam cara untuk mengurangi korosi salah satunya yaitu dalam mempertebal dan menutupi lapisan. Anodizing adalah proses pembentukan lapisan oksida pada aluminium yang melalui beberapa tahap yaitu cleaning, etching, desmut, anodize, dyeing, dan sealing. Dalam pelaksanaannya, variasi arus dan durasi waktu pencelupan benda uji saat proses anodizing mempengaruhi tipisnya lapisan yang terbentuk. Maka pengujian dilakukan dengan menggunakan metode pengujian SEM (Scanning Electron Microscope). Dengan menggunakan pengujian SEM tujuannya untuk mengetahui secara mudah melihat objek yang lebih kecil sehingga dapat dianalisa dalam pengaruhnya terhadap ketebalan lapisan. Untuk bisa mengetahui pengaruh variasi arus dan waktu pelaksanaan pengujian dilakukan sebanyak 5 titik bahan uji. Parameter kuat arus yang digunakan dalam penelitian ini yaitu 0.6 ampere, 1 ampere, dan 1.4 ampere dengan waktu yang berbeda 10menit, 25menit, 20menit, 25menit, dan 30menit, serta tegangan konstan sebesar 10V. Hasil ketebalan lapisan saat pengujian sifat isolatif akan didapat dari uji megger test. Selain itu juga uji SEM semakin tipis seiring bertambahnya variasi arus dan waktu. Hasil penelitian ini menunjukkan ketebalan lapisan terbaik pada anodizing kuat arus 0.6A, 1A, dan 1.4A sebesar 8,195 µm, 12,2 µm dan 11,270 µm. Waktu anodizing terbaik pada anodizing kuat arus 0.6A, 1A, dan 1.4A selama 10 menit, 20 menit, dan 30 menit.Sehingga semakin tinggi kuat arus dan semakin lama waktu anodizing maka akan membentuk nilai ketebalan lapisan semakin rendah. Dari hasil penelitian ini diharapkan dapat mengetahui pengaruh variasi arus 0.6-1.4A dan waktu pada proses anodizing terhadap ketebalan lapisan aluminium 6061.

The 6061 series aluminum is the main alloying element Al-Mg-Si. In everyday life the use of aluminum is very much including the series. Start consumption as needed for various fields. Aluminum has the property of easily forming corrosion caused by air or water. The lower the value of the corrosion rate, the better. There are various ways to reduce corrosion, one of which is to thicken and cover the coating. Anodizing is the process of forming an oxide layer on aluminum which goes through several stages, namely cleaning, etching, desmut, anodize, dyeing, and sealing. In practice, variations in current and the duration of immersion of the specimen during the anodizing process affect the thickness of the layer formed. Then the test was carried out using the SEM (Scanning Electron Microscope) testing method. By using SEM testing the aim is to find out which objects are smaller so that they can be analyzed in terms of their effect on the thickness of the layer. To be able to determine the effect of variations in current and time of execution of the test carried out as many as 5 points of the test material. The current strength parameters used in this study were 0.6 amperes, 1 ampere, and 1.4 amperes with different times of 10 minutes, 25 minutes, 20 minutes, 25 minutes, and 30 minutes, and a constant voltage of 10V. The results of the coating thickness when testing the insulating properties will be obtained from the megger test. In addition, the SEM test is getting thinner with increasing current and time variations. The results of this study showed that the best anodizing thickness of current 0.6A, 1A, and 1.4A was 8.195 µm, 12.2 µm and 11.270 µm. The best anodizing time for strong anodizing currents of 0.6A, 1A and 1.4A for 10 minutes, 20 minutes and 30 minutes. So that the higher the current strength and the longer the anodizing time, the lower the layer thickness value will form. From the results of this study it is expected to know the effect of variations in current 0.6-1.4A and time in the anodizing process on the thickness of the 6061 aluminum layer.
