St37 steel has been used in various industries due to its abundance and low cost. However, the high corrosion rate of steel in acidic environments is one of the limiting factors for its application. In this study, Ni-Cu composite coating reinforced with CNTs was applied on the st37 steel substrate. The extract of the Sarang Semut plant was added to the coating as inhibitory particles and the electrochemical behavior of the coating was investigated. The X-ray diffraction test was performed for phase analysis. Hardness, wear, and dynamic potential polarization tests were performed. Results showed that the presence of CNT particles improved the hardness, tribological performance, and electrochemical behavior of the coating. Also, the presence of Sarang Semut particles acted as a barrier and protected the surface of st37 steel from corrosion. It should be noted that these particles affected the kinetics and thermodynamics of corrosion reactions and were not involved in the reactions.

“…By increasing the concentration of the APE, the corrosion current density (i corr ) was notably decreased and the lowest i corr was obtained at 3% (v/v) apple pomace extract. The maximum inhibition efficiency (IE%) of APE calculated using i corr value was 83%, which is significantly more than that of pectin (78.7%) for X60 steel in 0.5 M HCl solution [79] and that of Sarang Semut (Myrmecodia Pendans) extract (65.21%) for low carbon steel in 3.5% NaCl solution [62]. By adding the extract at 3% (v/v), the corrosion potential (E corr ) of the steel increased by more than 85 mV, which shows that APE is an anodic inhibitor and the corrosion inhibition is attributable to change in the activation energy [14,21].…”

Preservation of metals in infrastructures and other assets requires cost-effective and sustainable solutions such as green corrosion inhibitors. This study assesses an apple pomace-derived green inhibitor synthesized by an innovative zero-waste method. Electrochemical measurements revealed the high performance of this liquid extract in reducing the corrosion of carbon steel in NaCl brine. The chemical composition of this inhibitor was characterized by liquid chromatography mass spectroscopy (LC-MS) to shed light on the corrosion inhibition mechanism. Based on LC-MS analysis, the results of surface analysis were interpreted. Specifically, the major corrosion inhibitor agent in the apple pomace extract was determined as C 26 H 50 NO 7 P (1-Linoleoylsn-glycero-3-phosphocholine), which can adsorb onto the steel surface to form a barrier layer and serve as a blocker of active anodic sites. Further study showed that the apple extract adsorption follows the Langmuir isotherm, and physical adsorption is dominant (vs. chemical adsorption). Theoretical calculations using quantum chemistry proposed a physisorption mechanism for the protection of steel by C 26 H 50 NO 7 P molecules.

“…To produce the extended structure of the pipe system, the most common metal used is carbon steel because of its effectiveness and availability as an economical metal despite that the fact corrosion resistance of carbon steel is relatively low [4] ; alternate metals with good corrosion resistance are costly. Thus, most industries prefer to rely on corrosion control and monitoring techniques to protect the metallic structures [5] to enhance their service life for obvious reasons. Corrosion inhibitors may be considered an essential chemical addition to protecting carbon steels, among several corrosion control methods; addition of a small concentration of inhibitors can minimize the rate of corrosion.…”

The investigation of Corrosion inhibition behavior of synthesized amino acid-based Schiff base inhibitor [(E)-5-nitro-N1-((E)-3-phenylallylidene) benzene-1,2-diamine] was carried out. Its adsorption in two types of (5%) soil solutions was studied at room temperature, using potentiodynamic polarization and gravimetric techniques. The inhibition efficiency obtained at the optimum inhibitor concentration (300ppm), were 23% in acidic and 70% in neutral electrolyte. Results illustrated that the inhibitor worked well in less acidic environment in one of the soil solutions which was relatively acidic than the other. Experimental data of potentiodynamic study also indicated that the inhibitor was more inclined to adsorb on the anodic sites of the carbon steel sample, thus the inhibitor can be categorized as the anodic inhibitor due to suppression of more anodic reaction on the carbon steel sample.
