The corrosion inhibition of AISI309 austenitic stainless steel by 2,2'-Bipyridyl in 0.5M H 2 SO 4 at 298K was studied using the mass loss’ method, the potentiodynamic polarization (Tafel), the linear polarization (LRP) and the electrochemical impedance spectroscopy (EIS). The results showed a mixed inhibition mode and an increase in the charge transfer resistance, due to inhibitor molecules’ ad...

The corrosion behavior of oxygen-free copper in anoxic sulfide solutions under nuclear waste disposal conditions was studied using electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) equipped with a focused ion beam (FIB), X-ray photoelectron spectroscopy (XPS) and Micro X-ray diffraction ( XRD). The film growth process and mechanism were elucidated using an Au mark...

is an AFM-based technique for materials and device characterization. The reflected microwave signal from the tip-sample interface holds information of the electrodynamic properties of the sample surface underneath the tip apex. Detecting and processing of the reflectance in real time allows sMIM to directly access the permittivity and conductivity of materials. When an AFM-type sMIM probe is sc...

Abstract The aim of this work was to investigate the effect microstructure Inconel 625 additively manufactured by laser powder bed fusion (LPBF) and laser-assisted directed energy deposition (LDED) on resistance corrosion in sulfuric acid solution. Corrosion tests lasted 30 days, 90 days 180 days. Microstructure characterization performed using light microscopy, scanning scanning-transmission e...

In this work, for the first time poly (benzoquinone) chromium (III) complex (PBQC) was synthesized with a one pot, one step, simple and fast method. This novel polymer was used for modification of graphite paste electrode for electrochemical determination of Mesalazine. Moreover, this novel modifier was characterized by Fourier transform infrared spectroscopy, Field emission scanning electron m...

In the present study, Ni-P-CNT composite coating was successfully fabricated via electroless plating. Scanning electron microscopy (SEM) was used to characterize the coatings. The effect of CNTs concentration in the bath on its content in the composite coatings was studied. Furthermore, the corrosion behaviour of the coatings with different contents of CNTs was evaluated using Tafel polarizatio...

In this study, Malvasylvestris flower extract (MFE) was used as a corrosion inhibitor for carbon steel in 1 M HCl solution. Malvasylvestris extract was analyzed by gas chromatography coupled with a mass spectrometry detector (GC-MS). Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) studies revealed that the inhibition efficiency increases with increasing MFE concent...

Composite electrodes of polyaniline/MnO2-Multi walled carbon nanotube (PANI/MnO2-MWCNT), MnO2-MWCNT nanocomposites and MWCNT was produced by the in situ direct coating approach. The supercapacitor performance of the nanocomposites was studied by Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM). The electrochemical properties of electrodes were also investig...
