In this paper, the possibility of using newly synthesized ionic liquid based on nicotinamide as a potential inhibitor copper corrosion in an acidic sulfate medium was investigated. Inhibition efficiency butyl-nicotinamide, [C4Nic]Br (pH=3) 0.1 mol/dm3 sodium sulphate solution analyzed potentiostatic polarization measurements and electrochemical impedance spectroscopy (EIS). It found that invest...

This work investigates the movement of anions during potentiostatic controlled reduction of novel composite materials consisting of high surface area cellulose substrates, extracted from the Cladophora sp. algae, coated with thin ( approximately 50 nm) layers of the intrinsically conducting polymer (ICP) polypyrrole. The coating was achieved by chemical polymerization of pyrrole on the cellulos...

Magnesium (Mg) is a promising implant material for orthopedic applications due to its biodegradability and desirable mechanical properties. However, in order for Mg to have wide-spread clinical relevance, engineering solutions that address the rapid degradation in physiological environments and promote increased bone-forming activity are necessary. The objective of this study was to develop an ...

Potentiostatic, galvanostatic and cyclic potentiodynamic depositions of polyaniline were studied by cyclic voltammetry and in-situ Raman spectroscopy. Multivariate analysis of the spectroelectrochemical data including evolving factor analysis, multivariate curve resolution and 2Dcorrelation spectroscopy was applied to resolve overlapped bands in Raman spectra and to assign them reliably. Oxidiz...

A research on the corrosion inhibition of mild steel pitting corrosion in concrete pore solution by sodium nitrite was carried out by employing potentiodynamic, potentiostatic polarization and zero resistance ammetery (ZRA) techniques. Passivity breakdown potential was decreased from the transpassive potential of 700 mV at the absence of chloride to a value of -50 mV when just 0.01M NaCl was ad...

In the present work, austenitic stainless steel 316L (SS316L) samples were implanted with Ni and Ni-Cr. A nickel-rich layer about 100 nm in thickness and a Ni-Cr enriched layer about 60 nm thick are formed on the surface of SS316L. The effects of ion implantation on the corrosion performance of SS316L are investigated in a 0.5 M H2SO4 with 2 ppm HF solution at 80°C by open circuit potential (OC...

In order to improve the corrosion and wear resistance of biomedical Ti-6Al-4V implants, a Ta₂N nanoceramic coating was synthesized on a Ti-6Al-4V substrate by the double glow discharge plasma process. The Ta₂N coating, composed of fine nanocrystals, with an average grain size of 12.8 nm, improved the surface hardness of Ti-6Al-4V and showed good contact damage tolerance and good adhesion streng...

One of the most important sources renewable energy worldwide is use solar energy, which developing rapidly, and power plants are becoming part infrastructure many countries. In this regard, titanium dioxide, has photovoltaic properties, used in conversion into electrical widely used. Purpose to develop a method for attaching nanostructured stable aqueous solutions, surface metal plate. Objects....

To evaluate the susceptibility of steels to hydrogen embrittlement, it must be charged and have its content controlled before any mechanical testing. In this study, permeation tests an iron sheet were performed during potentiostatic charging in various solutions containing ammonium thiocyanate obtain a guideline for efficient wide range contents. As polarization potential shifted negative direc...
