The inhibiting effect of some compositions of «Soling» series on low-carbon steel St3 in solutions of 5% and 15% HCl and 5% H2SO4 has been studied by the methods of polarization and gravimetric measurements. The protective action and the coefficient of inhibition of the corrosion process are calculated, the slopes of the Tafel sections in the cathode and anode regions of the polarization curves have been calculated. The influence of inhibitors on the kinetics of partial electrochemical reactions has been determined. The state of the surface of the samples has been estimated using micrographs. The high efficiency of inhibitors in acidic media has been shown.

Corrosion inhibitors are vital in industry for protection and prevention of surfaces from corrosion attack. There is need to have green inhibitors that are environmentally friendly and not hazardous to use. Extract from stem of banana (Musa species: Musa-Acuminata) was considered as green inhibitors. Extracts from the stem of banana was subjected to physico-chemical, phytochemical screening and corrosion test using gravimetric measurement with a low carbon steel flat bar coupon. The corrosion inhibition mechanism of the plant extract on the low carbon steel surface in 1M HCl and H2SO4 acid at different temperatures (30 to 60oC) showed that the inhibition efficiency (IE) increased with increase in concentration of the inhibitor (15ml to 75ml) but decreased with increase in temperature (303K to 333K) for the inhibitors throughout the test period, indicating a physisorption of extract on the carbon steel surface. The adsorption on the low carbon steel surface agrees with the Langmuir adsorption isotherm. The inhibition efficiency of the extract was above 50% in both media with banana extract having 69.55% inhibition efficiency in H2SO4 solution

Film Development

In the present work, corrosion inhibition of low carbon steel in a 1M H2SO4 solution by pectin nanoparticles extract was studied by potentiostatic and weight loss methods. Increasing the acid concentration leads to an increase in the corrosion rate of the electrode. The variable conditions of the pectin nanoparticles used in this investigation are (2 to 10g/l at 25oC). It was found that the concentrates acts as a compelling consumption inhibitor for gentle steel in an acidic medium. The hindrance process is credited to the adsorbed film development of the inhibitor on the metal surface of that protects the metal against corrosion. It was observed that the efficiency of the inhibition rose with increased inhibitor concentration up to the maximum level of 92% for 10 g/l at 25 oC. The results showed that the corrosion rate without the inhibitor was 2.263mpy while with the inhibitor 0.179 mpy, meaning that the rate of corrosion improved more than 90%. The results of the immersion time (1 h) at 25oC on the inhibition of the corrosion also indicated improved corrosion resistance. The results demonstrated that an extract of pectin nanoparticles could serve as an excellent eco-friendly, green corrosion inhibitor. Fourier- transform infrared spectroscopy (FTIR) results indicate that these nanoparticles contain various chemical bonds (C-C, CH2, C-O-C, and cellulose) with metal surfaces, lead to producing a barrier layer that protects the surface.

This article proposes a method for obtaining stable hydrophobic inhibitor dispersions, where the micelle core contains a hydrophobic solvent, a corrosion inhibitor and an organosilane. Such compositions can be used as polymer-type corrosion inhibitors for low-carbon steel. Using electrochemical methods, corrosion tests and X-ray photoelectron spectroscopy, features of the formation of polymeric layers of hydrophobic organosilicon dispersions were studied.
