Abstract

Abstract. This study aims to determine the extract of green cincau leaves (Cyclea Barbata Miers) as a corrosion inhibitor soaked in 3% NaCl corrosive medium. To determine the effect of concentration and temperature to connect steel, the average inhibitor is 0, 2, 4, and 6% and each temperature is 40℃ and 80℃. To find out the measurements done by the method, save weight. Corrosion rate at immersion temperature is 40℃ lower than speed at 80℃ immersion temperature. To find out the phase formed and the structure of the sample in XRD and SEM-EDS characterization. The X-Ray Diffraction (XRD) characterization results show that the phase formed is pure Fe. XRD results showed that the lowest Fe peaks were formed on samples without inhibitors at 80℃.The results of SEM characterization of PGDaun-80-6 steel also showed that it looked more corroded, and the PGDaun-40-2 sample looked slightly corroded. This result is reinforced by the percentage of corrosion products shown in the EDS results. Keywords:Corrosion inhibitors, green cincau leaves, leaf spring steel, NaCl.
