“…As shown in Figure 4 and Table 1, with increasing concentration of inhibitors, PETA/4ITU-0G and PETA/ 8ITU-1G decreased the corrosion current density (i corr ), and potentiodynamic polarization curves move toward low current density compared with the blank group, resulting in an increase in η p . The results from Table 1 show that the corrosion potential of carbon steel after adding PETA/8ITU-1G and PETA/4ITU-0G shifts less than 85 mV, 52 indicating that both PETA/4ITU-0G and PETA/8ITU-1G were mixed-type inhibitors. 53 These results revealed that the addition of PETA/4ITU-0G and PETA/8ITU-1G formed a dense protective film on the surface of the carbon steel to inhibit the corrosion process.…”

The potential of increasing use of soft water in a circulating cooling water system can solve scaling problem and improve water conservation efficiency; however, it will bring corrosion to equipment and pipelines. In this study, isothioureaterminated pentaerythritol core dendrimers with 0−2 generations (PETA/4ITU-0G, PETA/8ITU-1G, and PETA/16ITU-2G) were developed as phosphorus-free corrosion inhibitors for carbon steel in soft water. The corrosion inhibition performance and mechanism of these dendrimers were studied by weight loss analysis and electrochemical measurements, surface morphology analysis, and molecular dynamics (MD) simulations. The results show that the corrosion inhibition efficiency isand they can spontaneously adsorb on the carbon steel surface to form a protective film. The sulfur and nitrogen atoms in the terminal isothiourea of the dendritic polymers bound with iron through physical and chemical processes. The performance of isothiourea-terminated pentaerythritol core dendrimers was better than that of isothiourea-terminated pentitol core dendrimers. PETA/8ITU-1G was the most cost-effective inhibitor and showed a better inhibition performance than PETA/4ITU-0G owing to its numerous terminal isothiourea groups in the molecular structure, which helps form a stronger protective film. The central core and number of terminated groups of dendrimers both play a role in the corrosion inhibition performance.

“…Ionic liquids (ILs) are likely to get the attention of many researchers for their potential application as corrosion inhibitors in a variety of industries due to their low toxicity and outstanding efficacy. , The ionic liquids’ alkyl chain length significantly affects the rate of corrosion. The performance of ILs’ ability to inhibit corrosion is improved by an increase in the metal surface coverage brought on by an increase in the alkyl chain lengths of ILs. , …”

“… Naidu and Joseph (2022) state that corrosion in reinforced concrete happens when an aggressive substance, such as chloride, diffuses into the reinforcement. Although there are several ways to prevent corrosion, using inhibitors is still the most popular method ( Saha et al, 2015b ; Saha et al, 2015a ; Saha et al, 2016 ; Saha et al, 2019 ; Saha et al, 2021 ; Fouda et al, 2022 ; Saha et al, 2022 ; Wang et al, 2022 ; Bijapur et al, 2023 ; Li et al, 2023 ). Prior research has extensively examined the application of synthetic organic compounds with heteroatoms, heterocyclic rings, and aromatic rings to reduce corrosion aggression on steel.…”

Each year, the rising demand for palm oil generates large amounts of palm kernel shell waste. Discarded palm kernel shells can produce activated carbon, crushed shells, liquified fumes, and other derivatives; however, their indiscriminate disposal persists, raising issues related to the environment and economy. Therefore, the purpose of this study is to investigate the use of palm kernel shell as a corrosion inhibitor for thermo-mechanically treated steel in a seawater environment using gravimetric and electrochemical techniques, as well as surface tests at varying concentrations. The findings demonstrated that the palm kernel shell inhibited the cathodic and anodic processes by adsorption on the steel surface, which followed the Langmuir adsorption isotherm. The inhibitor exhibited a 98% inhibitory efficiency at 500 ppm concentration. Scanning electron microscopy analysis verified the thin films of the inhibitor on steel surface in seawater solution. Fourier transform infrared spectroscopy results show that the extract’s components prevent the steel corrosion through an adsorptive mechanism. According to the inhibitor economic evaluation, employing the palm kernel shell extract is less expensive than utilizing conventional inhibitors.
