“…Various parts of plants -seeds, fruit, and leaves, were extracted and used as corrosion inhibitors [1][2][3][4][5][6][7]. Punica granatum, commonly known as pomegranate is reported to be a rich source of anthocyanins (delphinidin, cyaniding, and pelargonidin), phenolic compounds (including hydrolysable tannins such as punicalin, pedunculagin, punicalagin, gallagic, and ellagic acid), and organic acids alleged to be responsible for its medicinal properties [8,9].…”

Abstract. Leave of Punica granatum extract (LPGE) as green inhibitor for the corrosion of mild steel in 1M HCl solution was studied using weight-loss and potentiodynamic polarization measurements. The results obtained revealed that LPGE has fairly good inhibiting properties for mild steel corrosion in 1M HCl solution, with efficiency of around 94 % at a concentration of 1 g/l. The inhibition was of a mixed anodic-cathodic nature. The film which is formed over the metal surface was analysed by FT-IR spectroscopy. Further examination using X-ray diffraction confirms the role of LPGE as an effective corrosion inhibitor for mild steel in acid media.

“…5, sample without the addition of inhibitors experienced a sharp increase in mass lost compared to other samples. This is because there is no inhibitor that will inhibit the occurrence of corrosion, so that the loss of mass more and more along with the length of time immersion [11], [22].…”

“…6, where Efficiency Inhibition of steel has increased with increasing inhibitor concentration, while the corrosion rate has decreased. The increase in inhibition efficiency may be attributed to the increase in number of adsorption of nutrients on the surface of steel which makes a barrier for mass and charge transfer and prevent further corrosion [22]. Table 1 shows the rate of corrosion decreases with increasing concentration of cacao peel extract inhibitors added.…”

Corrosion is a natural phenomenon that can not be prevented the process of occurrence, but the timing may be delayed.Various efforts have been made in reducing the impact of losses caused by corrosion. One such effort is to coat the metal surface with a thin layer. As well as other efforts is to use an inhibitor. Efforts have been made to reduce the impact of corrosion loss by synergizing surface coating and using of inhibitors. Deposition of a thin layer of Cu using electrodeposition method with 0.05 M CuSO4.5H2O electrolyte solution and addition of inhibitor of Theobroma cacao peels extract. In this research has been done some variation that is variation of electrodeposition time and variation of concentration of inhibitor of Theobroma cacao peels extract. Scanning Electron Microscope (SEM) characterization shows electrodeposition of a thin layer of Cu for three minutes, a voltage of three volts, and with the addition of an inhibitor of Theobroma cacao peels extract 1% producing a smooth, homogeneous and more uniform surface morphology. Based on the result of characterization with X-Ray Diffraction (XRD) obtained steel surface at electrodeposition with the addition of an inhibitor of Theobroma cacao peels extract, there are sharper peaks of Cu. Based on the corrosion test obtained value of Inhibition Efficiency inhibitor of Theobroma cacao peels extract amounted to 69.4% with the addition of 1%, and 81.9% with the addition of inhibitor 1.5%. Based on this, inhibitor of Theobroma cacao peels extract can reduce the attack rate of corrosion on the steel surface in corrosive media HCl 1N.

Corrosion inhibition and adsorption properties of the crude extract and polar extract of Theobroma cacao peels on mild steel in HCl 1.5M was studied using the method of weight lost and potentiodynamic polarization (Tafel). Inhibition efficiency were measured for immersion for 192 hours, the concentration of the extract 0.5-2.5% with an interval of 0.5% and the rang of temperature (303-323) K. Electrochemical polarization evaluated to know the type of inhibitor. Infrared spectra and GCMS were conducted to determine the extract compounds that act in the inhibition process. The surface morphology of samples was observed by a photo optical. The results showed that the corrosion rate decreases with increasing the concentration of the extract and increases with increasing temperature. Inhibition efficiency for crude extract and polar extract was 83.45% and 96.26% (weight loss), 85.23% and 92.08% (Tafel) and 72.29% and 83.95% (303 K) at 2.5% of concentration of extract. The increase in the efficiency of inhibition was also followed by an increase in the degree of surface coverage of a chemical adsorption is happening on the surface. Adsorption that occurred on the surface of mild steel obeys the Langmuir isotherm. This polarization curve indicates inhibitor behaves as mixture inhibitor with predominantly on cathodic inhibition. Apparently, the polar extract is more effective to reduce the corrosion rate than crude extract. The addition of polar extract of cacao into a solution of HCl is very effective to reduce the attack corrosion of the mild steel surface.
