Korosi Baja Di Muara Baru Jakarta Dan Indramayu Dengan Simulasi Pasang Surut Uji Wet-Dry

Abstract: The corrosive destruction of steel as material of maritime infrastructure had been investigated using simulated wet-dry test, loss weight, energy dispersive X-Ray spectroscopy (EDS) and X-ray diffraction (XRD) in seawater solutions of Muara Baru,Jakarta; Karangsong and Eretan regions, Indramayu. Controlled solution used as the comparison of natural seawater are 3,5% NaCl and 5% NaCl. The results shows that uniform corrosion took place on carbon steel after the exposure. The resistance of corrosion increases ra… Show more

“…Morphological tests on the round bar show that the corrosion formed in cylindrical steel is (uniform corrosion). The corrosion products formed are dominated by black grains (pearlite) compared to white grains (ferrite) [9,10] . The granules are in the form of small granules that are in the form of lines and are connected to each other, so that their shape is like a blooming flower.…”

“…Berdasarkan grafik intensitas pada Gambar 3 sampai dengan Gambar 6 terlihat bahwa pada saat perendaman 10 hari, laju korosi baja ringan mengalami kenaikan dibandingkan dengan perendaman 30 hari. Hal ini disebabkan karena adanya anion klorida yang berada dalam larutan NaCl dapat bersenyawa sebagai kation logam hasil reaksi anodik yang membentuk senyawa kompleks mudah larut, yang dapat meningkatkan reaksi elektrokimia dan laju korosi secara cepat (Priyotomo et al, 2019). Laju korosi mengalami kenaikan yaitu pada perendaman 10 hari, sehingga waktu perendaman ini disebut sebagai tahap inisiasi.…”

“…Laju korosi mengalami kenaikan yaitu pada perendaman 10 hari, sehingga waktu perendaman ini disebut sebagai tahap inisiasi. Pada tahap ini reaksi elektrokimia berjalan sangat cepat (Priyotomo et al, 2019), dimana dalam hal ini reaksi oksidasi (anoda) dan reaksi reduksi (katoda) berlangsung. Reaksi elektromia juga membutuhkan peranan oksigen (reaksi reduksi) dan ion klorida.…”

“…Kerusakan akibat proses korosi juga menyebabkan dampak buruk aspek ekonomi secara makro antara lain kerusakan di pembangkit tenaga listrik uap, gas dan panas bumi. Pengendalian korosi diperlukan untuk meminimal kerusakan antara lain melalui seleksi material [1], proteksi katodik [2], pelapisan [3], dan inhibitor [4,5].…”
