Abstract

Abstract. Coffee extract used as an inhibitor in carbon steel samples AISI 1020, soaked in 3% NaCl corrosive medium. By varying the immersion time by 4 days and 8 days, as well as the inhibitor concentrations of 0%, 3%, 5% and 7%. After the treatment of the sample, the results of the calculation of the corrosion rate were the slowest in the sample AISI 1020 8.7 and the fastest in the sample AISI 1020 4.0. The inhibitor used has the highest efficiency value in the sample AISI 1020 4.7. The XRD characterization results showed that the crystal structure formed was pure Fe phase. SEM characterization shows the surface morphology of the sample, visible clumps in the sample. The characterization of EDS in the sample shows oxygen (O) which indicates that the sample has been corroded.
