They evoked an important anticorrosion rate in alkaline solution thanks to the formation of thick, compact, and stable passive film.…”

The present work aims to study the anticorrosion and the photodegradation properties of titanate nanotubes (TiNTs) and vanadium doped-titanate nanotubes (V-TiNTs). Moreover, this article seeks to investigate the effect of doping TiNTs by vanadium species at different amount (2, 5 and 10 wt %). The raw materials (i.e:TiO 2 and V 2 O 5-TiO 2) are obtained by a sol gel process, while the hydrothermal treatment is chosen to achieve the hollow structure. The structural evolutions and morphological characteristics of materials have performed using various techniques such as: Scanning Electron Microscopy and Energy Dispersive X-ray (MEB/EDS), X-ray diffraction (XRD), UV-Visible in Reflection Diffuse spectroscopy (RD/UV-Vis) and Fourier Transform InfraRed spectroscopy (FTIR) analysis. However , the anticorrosion properties of the synthesized nanotubes are evaluated on mild steel corrosion in 1 N HCl using a weight loss method. All materials showed a potential inhibitor effect (up to 90 %) depending on the vanadium percentage and the inhibitor concentration. The photodegradation activity of the prepared materials is evaluated in the photodegradation of two organic pollutants: Methylene Blue (MB) and Malachite Green (MG) under UV-Visible irradiation. The obtained results underlined the improvement of photocatalytic activity of TiNTs by vanadium species. A conversion rate up to 96 % is achieved at reduced time. Therefore, the prepared materials could be suitable for the anticorrosion of mild steel and the photodegradation of organic pollutants.

“…It can be seen that all specimens have reached a sufficient steady state with a stability lower than 1 mV/s. All curves displayed an increase of potential in the positive direction starting from the beginning of the test until a steady state was reached, and they showed no sign of noteworthy oscillation, which is an indication of passive film growth and stabilization . As seen in the figure, the activity of 316 stainless steel and CoCrMo alloy were considerably higher (>0.3 V) than the other materials.…”

Corrosion behavior is an important parameter for metallic biomaterials used in the body environment. To mimic bodily fluids, simulated body fluid (SBF) has been used extensively. Even though many studies focus on corrosion inside SBF, SBF has a very time consuming and delicate preparation procedure and contains no essential and organic components for the cell environment, which may affect corrosion kinetics. We aimed to investigate whether corrosion behavior or kinetics change in different solutions, SBF and Dulbecco's modified Eagle medium (DMEM). For this purpose, five commonly used metallic biomaterials, AISI 316 stainless steel, CoCrMo alloy, CP‐Ti, Ti6Al4V, and Ti6Al7Nb were subjected to open circuit measurements, cyclic polarization, and electrochemical impedance spectroscopy. Quantitative analyses were performed and surface topography was investigated via scanning electron microscope and a roughness tester. We observed that the materials exhibited similar behaviors in SBF and DMEM but the corrosion kinetics were somewhat different and the results obtained from DMEM were time dependent.

“…Besides, the corrosion potential (E corr ) was becoming more electrochemically negative. E corr values showed that when the value becomes more negative, the Tafel curve is prone to the less noble region, and the corrosion rate is increasing [22][23][24]. The calculated corrosion rate in the highest molarity 1.00 M H 2 SO 4 is 4.75 x 10 6 mpy.…”

This work discussed the corrosion behaviour of the internal surface of pipeline steel caused by petroleum products' composition, particularly crude oil. Internal and external pipeline corrosion is the notable cause of pipeline failure in Malaysia's oil and gas industry. However, internal corrosion is preferred to be concerned in this work because it involved one of the significant corrosive media in crude oil, such as sulfur content. This project aims to find the sulfur concentration in the crude oil using Fourier transform infrared spectroscopy and atomic absorption spectroscopy. The corrosion rate, corrosion current and corrosion potential of the API 5L X65 grade carbon steel pipeline in different simulated H 2 SO 4 solution concentrations were carried out using the Tafel extrapolation technique. The samples' corrosion properties were morphologically measured through the optical microscope, scanning electron microscope, and energy dispersive X-ray analyses. The results showed pipeline steel's corrosion rate significantly increased with increasing H 2 SO 4 concentrations. The corrosion products formed on the pipeline steel surfaces were mainly composed of iron sulphate, iron sulphide, and iron oxide. These findings are crucial to understanding the corrosion behaviour caused by crude oil and should be further investigated with the other influential factors such as temperature and petroleum flowing velocity.
