Protection of Galvanized steel from corrosion in salt media using sulfur nanoparticles

Metal oxide nanoparticles demonstrate uniqueness in various technical applications due to their suitable physiochemical properties. In particular, yttrium oxide nanoparticle(Y2O3NPs) is familiar for technical applications because of its higher dielectric constant and thermal stability. It is widely used as a host material for a variety of rare-earth dopants, biological imaging, and photodynamic therapies. In this investigation, yttrium oxide nanoparticles (Y2O3NPs) was used as an ecofriendly corrosion inhibitor through the use of scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FT-IR), UV-Visible spectroscopy, X-ray diffraction (XRD), and energy dispersive X-ray spectroscopy(EDX), the physico-chemical characterization of Y2O3NPs was examined. The primary characteristic peak of YOY at 565 cm-1, which indicates the synthesis of nanoparticles, is seen in the FT-IR spectra. The XRD pattern showed that a single phase cubic structure of YONPs with an Ia-3 space group had formed. SEM was used to examine the surface morphology. The composition of Yttrium and oxygen in Y2O3NPs was determined to be 78.74% and 21.26%, respectively, according to the EDX results. The anticorrosive behavior was tested by polarization curve in 18.204% CaCl2 solution at five temperatures in the range 293- 313 K. Various concentrations 0.15 0.26 and 0.37 of N Y2O3NPs coating on the carbon steel surface were applied using the electrophoresis deposition method. The obtained results indicated that Y2O3NPs formed a protective film acts as a physical barrier for the protection of steel alloy. Additionally, corrosion protection efficiency values of 0.26 N Y2O3NPs coating were superior to that of 0.15 and 0.37 N Y2O3NPs coating, respectively.

“…The aluminum gained (Uptake) resulting from the aluminumization process increases with time according to the parabola relationship as shown in Fig . 3, which indicates that the diffusion process governs the coating process 25 and Fig. 4 shows the relationship of the thickness of the resulting coating as a function of time, which also obeys the law of parabola.…”

This research aims to modify the components of stainless steel alloy by the method of surface engineering through the single diffusion coating technique in order to obtain new alloys with high efficiency in resisting harsh environmental conditions. Steam a mixture of sodium chloride ( ) and sodium sulfate ( ) at a temperature of 900 and then compare it with the base alloy. The results showed that the alloys produced in this way are very efficient. The results showed that the aluminum coating showed high efficiency in resisting oxidation and provided better protection for a longer time compared to the uncoated alloy due to the oxide crust layer formed with high adhesion as well as the aluminum-rich phases, whether the phases were nickel-aluminum or iron-aluminum. The results also showed that the thickness of the coating and the weight gain of the alloy is subject to the parabola relationship with time.

The effect of barley seed extracts on the corrosion of carbon steel in 1M hydrochloric acid at different temperatures was investigated from the perspective of their potential use as green inhibitors in the cleaning and descaling processes in heat exchangers. A 50% ethanol/water (vol) solution was used for extraction. Two extraction methods were used: soaking and ultrasound. The inhibition mechanism of the inhibitor that gave the best efficiency was investigated by studying the adsorption and corrosion processes by electrochemical methods (potentiodynamic polarisation (Tafel curves) and electrochemical resistance spectroscopy) and thermodynamic calculations. The results of the study showed no effect of the extraction method on the inhibition behavior, the inhibition as a function of concentration showed a significant increase in the inhibition efficiency up to concentration 400 ppm, then it appeared independent of it in both methods. However, the inhibition efficiency of the soaking method was higher at 800 ppm (87.01% compared to 80% for the ultrasound method). The study of the inhibition mechanism of this extract indicated the possibility of chemical adsorption. Inhibition activity increased with temperature.
