“…It is obvious from Figure 1a,b that the presence of BUT in the corrosive solution had corrosion inhibiting effect. The appearance of a depressed semicircle with larger diameter (Figure 1a) and the suppression of the corrosion current density (Figure 1b) in the presence of BUT are indicators of API 5L X60 corrosion inhibition [30]. The corrosion inhibition performance by BUT is found to improve with increasing concentration with the largest semicircle (Figure 1a) and the lowest corrosion current density (Figure 1b) produced by the highest studied BUT concentration (700 mg/L).…”

“…Common synergists include formic acid [26,27] (used at a concentration range of 0.5 to 10 wt.% [22]), potassium iodide [10,22,28] (used at a concentration range of 0.5 to 10 wt.% [22]), copper halides [22], and metals ions (e.g., Zn(NO 3 ) 2 , Sb 2 O 3 , SbCl 3 , Sb 2 O 5 , etc.) [22,29,30], which are used at the concentration range of 1-1.5 wt.% [22]. This work was thus designed to examine the effect of the addition of different concentrations of Zn(NO 3 ) 2 , KI, and formic acid on the corrosion inhibition performance of butanolic extract of date palm leaves for API 5L X60 carbon steel in 15 wt.% HCl solution at 25-60 • C. To accomplish this task, the mass loss, electrochemical (electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), and linear polarization resistance (LPR)), and surface screening (scanning electron microscopy (SEM), energy dispersive spectroscopy (EDAX), and atomic force microscopy (AFM)) techniques were deployed for anticorrosion studies.…”

The quest to replace toxic chemicals in the nearest future is revolutionizing the corrosion inhibitor research world by turning its attention to plant biomaterials. Herein, we report the corrosion inhibiting potential of butanolic extract of date palm leaves (BUT) on the corrosion of API 5L X60 carbon steel in 15 wt.% HCl solution. The mass loss, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), linear polarization (LPR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX), and atomic force microscopy (AFM) techniques were employed in the investigation. We also report the effect of intensifier additives, namely formic acid (FA), potassium iodide (KI), and zinc nitrate (Zn(NO3)2) as well as temperature on the corrosion inhibiting performance of BUT. BUT exhibits inhibiting ability but the extent of inhibition is dependent on concentration, temperature, and intensifiers’ concentration. At 25 °C, 200 mg/L BUT and 700 mg/L BUT protected the carbon steel surface by 50% and 88%, respectively. The addition of 3 mM FA and 5 mM KI to 200 mg/L upgraded the extract performance to 97% and 95%, respectively. Zn(NO3)2 performs poorly as an intensifier for BUT under acidizing conditions. The adsorption of BUT + FA and BUT + KI is synergistic in nature whereas that of BUT + Zn(NO3)2 drifts towards antagonistic behavior according to the calculated synergism parameter. Increase in the system temperature resulted in a slight decline in the inhibition efficiency of BUT + FA and BUT + KI but with efficiency of above 85% achieved at 60 °C. The SEM and AFM results corroborate results from the electrochemical techniques.

“…According to the literature, molecules containing P, N, S, and O atoms, as well as molecules with double or triple bonds, are better adsorbed on the metal surface and thus more effective inhibitors [6][7][8]. Studies on the use of environmentally friendly molecules are being conducted in this field because the majority of organic inhibitors used are toxic and have negative effects on people and the environment [9][10][11][12]. Natural plant extracts have become popular for this purpose in recent years [13][14][15][16][17][18][19][20].…”

Bu çalışmada, ışgının çiçek (RRF), yaprak (RRL) ve kök (RRR) gibi farklı bölgelerinin ayrı ayrı özütleri hazırlanarak asidik ortamda bakırın korozyonuna koruma etkileri incelenmiştir. Böylelikle ışgının kullanılmayan diğer kısımlarının da faydaya dönüştürülmesi mümkün olabilecektir. Bu amaçla, RR özütlerinin 1 M HCl çözeltisinde 1000 ppm çözeltileri hazırlanmıştır. Bakır metalinin bu çözeltilerdeki elektrokimyasal davranışları açık devre potansiyelinin zamanla değişimi (Eocp-t), elektrokimyasal impedans spektroskopisi (EIS), lineer polarizasyon direnci (LPR) ve potansiyodinamik polarizasyon (PP) teknikleri ile incelenmiştir. Bakırın korozif ortam ile muamelesi sonrasında yüzeyi taramalı elektron mikroskopu (SEM), enerji dağılımlı X-ışını spektroskopisi (EDX) ve temas açısı ölçümleri ile incelenmiştir. Elde edilen bulgular, RR’nin farklı bölgelerinden elde edilen özütlerin bakırın asidik ortamdaki davranışına etkilerinin farklı olduğunu göstermiştir. En iyi koruma RRF özütünde elde edilmiştir. RRR özütü ise bakırı 1 M HCl çözeltisinde korozyona karşı koruyamamaktadır. Yüzey analizleri bitki özütlerinin metal yüzeyinde koruyucu bir film oluşturduğunu göstermiştir.

“…Tian et al (2015) indicated that inclusion of 8-Hydroxyquinoline (8-HQ) into a hybrid silane film formulation can result in precipitation of insoluble Me n (8-HQ) n complexes in defects, improving the corrosion resistance of AA 2024-T3 in NaCl solution. Alinejad et al (2017) took advantage of the inhibition synergism of zinc cation and 2-mercaptobenzoxzole to formulate an eco-friendly silane sol-gel coating characterized with active corrosion protection. According to Chen et al (2015), incorporation of TiO 2 nanoparticles into the bis-[triethoxysilylpropyl] tetrasulfide silane film makes it more compact because of the strong chemical interaction between Si and Ti atoms which could control the corrosion of 304 stainless steel in 3.5 per cent NaCl solution.…”

“…Moreover, we have already used some organic and inorganic inhibitors [e.g. ZnCl 2 (Alinejad et al , 2016), zinc acetylacetonate (ZAA) (Taheri et al , 2017) and mercaptobenzoxzole (Alinejad et al , 2017)], as well as nanoparticles [e.g. clay (Asadi et al , 2014a; Asadi et al , 2014b) and nickel ferrite (Gharagozlou et al , 2016)] individually in the formulation of silane coating to increase the corrosion resistance of steel substrate in NaCl solution.…”

Purpose This paper aims to enhance the barrier properties and active protection of a water-based silane coating on mild steel through nanoclay and zinc acetylacetonate simultaneously included into the formulation. Design/methodology/approach The corrosion protection performance of the silane sol-gel coatings with no additive, zinc acetylacetonate, nanoclay and nanoclay + zinc acetylacetonate was monitored using electrochemical impedance spectroscopy during 5 h of immersion in a sodium chloride solution. Moreover, the surface of coatings was analyzed using a field emission scanning electron microscopy equipped with an energy dispersive X-ray spectrometer (FESEM-EDX) and water contact angle measurements. Findings In electrochemical impedance spectroscopy analysis, the impedance at low frequencies, coating resistance and charge transfer resistance were the parameters considered which indicated the superiority of silane coating formulated with both nanoclay and zinc acetylacetonate. According to the results of FESEM/EDX and water contact angle measurements, the superiority was linked with the enhancement in the barrier properties in the presence of nanoclay, as well as function of the corrosion inhibitor at coating–substrate interface. Originality/value According to the literature, there is no research conducted to study the impact of the simultaneous use of nanoclay and zinc acetylacetonate on the barrier properties and active protection of an eco-friendly silane sol-gel coating including glycidyloxypropyltrimethoxysilane, tetraethoxysilane and methyltriethoxysilane on mild steel in a sodium chloride solution.
