“…The tests were conducted three times, with approximately 99% reproducibility. The test sample preparation and experimental process for electrochemical, surface, and weight loss techniques were related to the one reported in the literature Equations and were employed to evaluate the corrosion rate (CR) and percentage inhibition efficiency at different inhibitor concentrations, respectively. CR = 87.6 W D × A × T 0.25em where T is the exposure time (hour), D is density (g/cm 2 ), A is area (cm 2 ), and W is weight loss (mg). IE ( % ) = CR false( uninhibited false) − CR false( inhibited false) CR uninhibited × 100 where CR uninhibited and CR inhibited are the corrosion rate in the absence and presence of an inhibitor, respectively.…”

There is a high demand for eco-friendly, effective, and high-performance corrosion inhibitors for industrial applications. Thus, the corrosion property of aluminum alloys was studied in essential oil-containing sodium chloride solution at various concentrations. Potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), surface tests, and weight loss analysis were used to study the corrosion inhibition mechanism of the essential oil. The essential oil showed the highest inhibition efficiency of 97.01% at 1000 ppm. A high efficiency of 96.03% was achieved even after 168 h of exposure. The potentiodynamic polarization test showed that the essential oil is a mixed-type inhibitor. EIS results show better adsorption of the oil on the surface of the aluminum at increased inhibitor concentrations. The Langmuir’s adsorption isotherm model was found to describe the adsorption behavior. The surface morphology of the uninhibited and inhibited specimens examined by a scanning electron microscope equipped with an energy-dispersive X-ray spectroscope confirmed the protective film of the inhibitor molecules on the aluminum surface.

“…This experiment was carried out three times at ambient temperature for each exposure time, and the average value of the loss in weight was documented. From this weight loss value, the surface coverage (θ), corrosion rate (mm/year), and inhibitor e ciency (%) were calculated using equations reported elsewhere [36,38].…”

This research aims to identify cheap, effective, and green inhibitors from agricultural waste (coconut shell) as sustainable inhibitors for pure cast aluminium corrosion in 0.5 molar sulphuric acid medium at different concentrations. The inhibitive effect of coconut shell (CS) in 0.5 molar sulphuric acid solutions on aluminium was studied using series of standard corrosion monitoring methods: gravimetric and electrochemical techniques. The nature of adsorption and aluminium surface morphology was conducted with scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM/EDX) method. The obtained result implies that the CS can serve as an environmentally friendly inhibitor for aluminium corrosion in 0.5 molar H2SO4 environments with the highest corrosion inhibition efficiency of 99% at 10 g. The inhibition mechanism was proposed to be physical adsorption and fits the Langmuir adsorption isotherms. The inhibitive effect of CS was proposed to be a mixed inhibition mechanism as shown by the potentiodynamic polarization method. The SEM and EDX observation show that the CS species formed a protective layer on the aluminium surface. The results obtained confirmed that CS is a sustainable inhibitor, which could be used in the industry as an environmentally friendly corrosion inhibitor.

“…The plot of corrosion rates and inhibition efficiency was plotted from the obtained data during the immersion time. The corrosion rate in mm/year and inhibition efficiency was calculated according to equations (1) and (2) [22]: CR 0 and CR are the FSS corrosion rates in inhibited and uninhibited acid solutions.…”

This study examined the corrosion inhibiting properties of parsley (petroselinum sativum) essential oils, for Type 430 ferritic stainless steel in 0.5 molar sulphuric acid solutions. In this study, weight loss, electrochemical and scanning electron microscope techniques were used in gaining a detailed understanding of inhibition effects of parsley (petroselinum sativum) essential oils (PEO) on Type 430 ferritic stainless steel corrosion. The inhibitor studied exhibits good anti-corrosion performance with 98.65 % inhibition efficiency. This result could be ascribed to the adsorbed PEO on the surface of the stainless steel, and this was verified by surface visualization using optical and scanning electron microscope techniques while the crystallographic variation of the inhibited sample is studied by X-ray diffraction (XRD). The adsorption of PEO onto stainless steel surface is controlled by Langmuir adsorption isotherms. Optical images of non-inhibited specimens showed a severely corroded surface with a visible macro pit on the stainless steel from sulphuric solutions. The inhibited sample shows improved surface owing to the surface protection effect of PEO molecules. The corrosion inhibition performance of PEO is due to the presence of active constituents which enhanced the film formation over the surface of the metal, thus, mitigating corrosion.
