“…ZnAl-CO 3 layered double hydroxide precursor buffer layers were transformed to well inter grown ZIF-8 coatings in that study 28 . A recent research created an anticorrosive coating for the petrochemical industry using Samarium (III) nitrate and [bis(phosphonomethyl) amino] methyl phosphonic acid (ATMP) to preserve mild steel in saline solutions 29 . According to a thermodynamic research 30 , the extremely excellent inhibitory property of MOF on metal surface was attributed to chemisorption of MOF on metal surface 30 .…”

The effects of [Co2 (SCN) 4(hmt)2(H2O)6. H2O] (SC1) and [Co (CN)6 (Me3Sn)3(H2O). (qox)] (SCP2) MOF as corrosion inhibitors on C-steel in 0.5 M sulfuric acid solutions are illustrated utilizing mass reduction (MR), electrochemical [potentiodynamic polarization (PP), and AC electrochemical impedance (EIS)]. The experiments revealed that as the dose of these compounds rose, the inhibition efficacy (IE percent) of C-steel corrosion improved, reaching 80.7–93.1% at dose 25 × 10−6 M for SC1 and SCP2, respectively. IE percent, on the other hand, dropped as the temperature range grew. SC1was adsorbed physically and chemically (mixed adsorption) but SCP2 was adsorbed physically on the surface of C-steel and conformed to the Langmuir adsorption isotherm equation. The PP studies revealed that these compounds act as mixed kind inhibitors. To establish the morphology of the inhibited C-steel surface, scanning electron microscopy (SEM), energy transmitted X-ray (EDX), and atomic force microscopy (AFM) studies were used. All tested experiments were in good agreement.

“…When blank Q235 steel is immersed in H 2 SO 4 solution for 72 h, the contact angle is changed to be 0°, exhibiting a complete wettability, which may be attributed to the iron oxide and hydroxide on the steel surface as well as high roughness, leading to water droplets to readily spread on the steel surface. 50,51 As we know, the adsorbed inhibitors on the substrate's outer surface could effectively influence the contact angle. As SQDs are present in H 2 SO 4 solution, the contact angle is 25.2°, compared to the blank Q235 steel, the contact angle is enhanced which is probably attributed to the fact that hydroxyl groups on SQDs are broken during immersion processes and water-soluble SQDs transfer to water-insoluble SQDs.…”

Generally, single organic or inorganic inhibitors could effectively inhibit corrosion for metallic materials; however, there are rarely reports about the hybrid corrosion inhibitors consisting of organic and inorganic inhibitors. Thus, in this work, we synthesize a hybrid environment-friendly water-soluble corrosion inhibitor (Sb quantum dots) containing Sb, Sb2O3, Sb2O4, and carbon using the electrochemical exfoliation method. The inhibition effectiveness in short- and long-term immersion tests is measured using electrochemical methods, weight loss, and surface analysis. The results exhibit that the corrosion inhibition efficiency sensitively relates to the concentration of Sb quantum dots (SQDs), which achieves the largest value as the concentration of SQDs increases to 200 mg/L. Atomic force microscopy, scanning electron microscopy, and contact angle analysis reveal that the SQDs well-disperse on and cover the Q235 steel surface at 200 mg/L. According to the Langmuir adsorption data, the physicochemical adsorption and effective antioxidation of SQDs on the passivated Q235 steel surface are in charge of the effective corrosion inhibition efficiency in 0.5 M H2SO4 solution.

“…Organic inhibitors containing heteroatoms, such as oxygen, nitrogen, sulfur, and phosphorus atoms easily form a layer of organic-iron complexes by absorption on steel surfaces [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. The adsorption layer acts as a physical barrier between the steel surfaces and the corrosive environment to provide effective protection against corrosion [ 1 , 2 , 3 , 4 , 5 ]. This phenomenon has been applied to restrain the internal corrosion of steel pipelines and the unexpected dissolution of steel structures during the acidizing process; therefore, the corrosion life of steel can be extended by a corrosion inhibitor [ 6 ].…”

Corrosion Inhibition of Mild Steel and 304 Stainless Steel in 1 M Hydrochloric Acid Solution by Tea Tree Extract and Its Main Constituents

Tea tree extract, containing antioxidant constituents α-terpineol, terpinen-4-ol, and α-terpinene, has a wide range of applications in the cosmetic, food, and pharmaceutical industries. In this study, tea tree extract showed an anticorrosive effect under 1 M HCl solution on mild steel (MS) and 304 stainless steel (STS). Uniform corrosion for MS and pitting corrosion for STS at 298 K were retarded, with inhibition efficiencies of 77% and 86%, respectively. The inhibition of uniform and pitting corrosion was confirmed by scanning electron microscopy and laser scanning confocal microscopy in terms of surface roughness and pitting morphologies. The most effective constituent contributing to the inhibitory performance of tea tree extract was revealed to be α-terpineol, with an inhibition efficiency of 83%. The adsorption of tea tree extract was confirmed by surface characterization analysis using Fourier transform infrared spectroscopy, Raman spectroscopy, and Electrochemical impedance spectroscopy. Interestingly, G- and D-peaks of Raman spectra were detected from the inhibited steels, and this finding is the first example in the corrosion inhibition field. The anticorrosion mechanism can be explained by the formation of organic-Fe complexes on the corroded steel surface via electron donor and acceptor interactions in the presence of an oxygen atom of the hydroxyl group or ether of organic inhibitors.
