“…Conversely, at a distance of 5 cm and 15 cm, the loss of mass when immersed in the corrosion solution is smaller than the loss of mass at a distance of 10 cm. This is in accordance with the weight loss method of calculating the corrosion rate which states that the greater the mass loss value, the higher the corrosion rate value [5].…”

Aluminum foil is used more often than actual aluminum in everyday life because aluminum is actually quite unstable and is not suitable for securing heavy containing objects. For car wheels, aluminum is mixed with manganese and then hardened to withstand the load. Using aluminum alloys requires an electroplating process to increase corrosion resistance, decorative value and friction resistance. The purpose of this study was to determine the properties of anodized cathode aluminum alloy and the required coating time. In this study, a quantitative experiment used 20 samples. The results showed that there were defects in the aluminum alloy lattice, but not too significant. Different corrosion rate values were shown using electrolysis periods of 30 minutes and 60 minutes combined with anode-cathode distances of 5 cm, 10 cm and 15 cm. The group with 30 minutes of coating time and 5 cm anode-cathode distance had the highest corrosion rate (0.853 mm/year), while the group with 30 minutes of coating time and 10 cm anode-cathode distance had the lowest corrosion rate (0.610). The group with 60 minutes of coating time and 10 cm distance between the anode and cathode had the highest corrosion rate of 1,564 mm/year, while the group with 60 minutes of coating time and 15 cm distance had the lowest corrosion rate. The anode-cathode distance partially affects the corrosion rate of aluminum alloy electroplating. The smaller the distance between the anode and cathode, the higher the corrosion rate of the aluminum alloy. The longer the coating lasts, the higher the corrosive rate of the Al alloy.

“…This method calculates the weight loss caused by corrosion by using interval inspection. To calculate the weight loss due to corrosion, use the formula below [5]. In this procedure, the actual weight of the test item-the object whose corrosion rate is to be determined-is measured; the lost weight is calculated from the original weight.…”

“…Serta kelebihan menggunakan sistem ini yaitu hasil lebih baik, lebih mudah dilakukan, serta murah dalam ongkos produksinya [1]. Menurut [7] semakin tinggi temperatur larutan elektrolit pada proses elektroplating maka ketebalan lapisan akan semakin tebal dan juga nilai ketahanan korosi semakin tinggi. Pada penelitian yang dilakukan [8] baja ST 41 yang mengalami electroplating mengalami kenaikan nilai kekerasan dibanding dengan sebelum di electroplating.…”

Dunia industri pelapisan logam mengalami peningkatan yang sangat cepat, mulai dari pelapisan bahan, jenis pelapisan hingga hasil dari pelapisan tersebut. Untuk menanggulangi bahaya kerusakan pada logam salah satunya korosi diperlukan cara untuk melindunginya yaitu dengan menggunakan pelapisan logam salah satunya electroplating. Baja ST41 adalah salah satu dari baja karbon rendah. Baja ini termasuk dalam golongan baja karbon rendah karena dalam komposisinya mengandung karbon sebesar 0,08%-0,20%. Prosedur penelitian yang akan dilakukan dalam penelitian ini yaitu dengan cara memotong benda kerja baja ST 41 yang berdiameter 40 mm dengan panjang 20 mm sampai jumlah total 14 spesimen dilakukan electroplating menggunakan variasi 5 V dan 10 V serta mengggunakan variasi waktu 15, 30 dan 45 menit. Hasil electroplating pada tegangan 5 volt dan 10 volt memperlihatkan bahwa ketebalan terendah berada pada waktu 15 menit sebesar tegangan 5 Volt sebesar 2,316 µm dan ketebalan tertinggi pada waktu 45 menit tegangan 10 volt dengan tingkat ketebalan 7,93 µm. Hasil kekerasan pada baja ST 41 tegangan 5 dan 10 volt memperlihatkan bahwa tingkat kekerasan terendah pada variasi waktu 30 menit tegangan 5 Volt sebesar 147 HB dan nilai kekerasan tertinggi pada variasi waktu 45 menit tegangan 10 volt sebesar 170 HB.
