AISI 1070 steel is a material that has corrosion when it reacts with the environment. One way to inhibit the corrosion rate is by using organic inhibitors. The organic inhibitors used mango leaves and mango rinds with variations in the concentration of organic inhibitors of 0%, 6%, and 8%, respectively. This study aimed to determine the effectiveness of mango leaf extract and mango rinds as an inhibitor against the corrosion rate of AISI 1070 Steel. The extraction was carried out using the Maceration Method. Fourier Transform Infrared (FTIR), Potenzyodinamic, and Weight Loss tests were carried out in this study. FTIR results show that both mango rinds and mango leaf have ingredients that were able to inhibit the corrosion rate, such as flavonoid functional groups including C – H, C = O, and C – O. Using the weight-loss method, the best corrosion rate was found in the mango rinds extract with a concentration of 8 mL, which was 31.784 mm/year with an inhibition efficiency of 92%. The highest corrosion rate was in 2M H2SO4 solution using potentiodynamic, without a mixture of inhibitors, that is 0.15589478 mm/year.
<p>Pembuatan kawat umumnya termasuk dalam pengerjaan dingin atau <em>coldworking </em>yang berarti proses pengerjaan dilakukan dibawah suhu rekristalisasi dari logam tersebut, pengerjaan dingin akan mempengaruhi sifat mekanik diantaranya kekerasan, kekuatan dan keuletan. <em>Wire drawing </em>mampu menunjukan perubahan sifat mekanik tersebut dan parameter yang mempengaruhi ialah sudut cetakan atau <em>die</em>, temperatur, pelumas dan juga persentase reduksi. Metode dari penelitian ini ialah membandingkan hasil simulasi pada <em>software Ansys Workbench 19.0 </em>dan hasil perhitungan dengan teori yang sudah ada, dengan tujuan mengetahui pengaruh dari variasi sudut <em>die </em>terhadap nilai tegangan alir dan gaya penarikan. Dalam penelitian ini material <em>wire </em>yang digunakan ialah baja AISI 1006 ditarik melalui beberapa variasi sudut die 12º, 14º dan 16º, dengan koefisien gesek 0,03 untuk masing-masing persentase reduksi kawat 17,36%; 9,75%; dan 19,95%. Hasil yang didapat dari penelitian ini adalah rata-rata tegangan alir dan gaya penarikan. Persentase perbedaan hasil simulasi dan teoritis dari rata-rata tegangan alir dan gaya penarikan memiliki rata-rata sebesar secara berurutan 1,47% dan 8,35%, dengan nilai tegangan alir terbesar 158,508 Mpa dan gaya penarikan terbesar 502,63 N .</p><p><strong>Kata kunci:</strong> Baja AISI 1006; Finite Element Methode, Sudut die, Wire Drawing</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
