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
