vanillin is an interesting corrosion inhibitor because of its safe use and high solubility inwater. the effect of vanillin on the corrosion inhibition of carbon steel in 1.0 mhydrochloric acid solution has been studied using potentiodynamic polarization,electrochemical impedance spectroscopy (eis) and electrochemical noise (en) techniques.the effect of temperature on the rate of corrosion in th...

A corrosion inhibitor suitable for industrial production and field application was rapidly synthesized from benzene-1,2-diamine, benzaldehyde, methanol, hydrochloric acid, and FeCl3. The mechanism of corrosion and its inhibition was proposed. We investigated the effect of the main reactants on corrosion rate, and optimal synthetic composition (benzene-1,2-diamine 10 g, b...

Abstract Detrimental corrosion is an ever-concerning challenge for metals and alloys. One possible remedy to apply organic inhibitors. Despite progress in molecular assembly inhibitor research, better mechanistic insight on the level needed. Here we report behavior of well-defined artificial interfaces created by micro-contact printing thiol-inhibitor molecules subsequent backfilling. The obtai...

In this work we proposed to evaluate the corrosion resistance of four different alloys by electrochemical techniques, a binary alloy Cu10Al, and three ternary alloys Cu10Al-xAg (x = 5, 10, and 15 wt.%) to be used like biomaterials in dental application. Biomaterials proposed were tested in artificial saliva at 37°C for 48 h. In addition, pure metals Cu, Al, Ag, and Ti as reference materials wer...

The chemical content of water pH, mineralization, alkalinity, hardness, calcium and magnesium compounds, carbon dioxide free provide guidance about buffering capacity of water. Therefore, if the mineralization and pH is low, the water is aggressive towards the materials used in manufacturing pipes concrete, steel, HDPE, PVC, PAX. If the mineralization is high, the pH is high, too and the water ...

An optical fiber corrosion sensor (OFCS) based on iron-carbon (Fe-C) film was researched. OFCS was formed by electroplating a Fe-C film on fiber Bragg grating (FBG)metalized with silver film bymagnetron sputtering. There was a more than 430-pm change of FBG wavelength when Fe-C film was seriously corroded. Compared to electrochemical method, the optical fiber sensor shows dominance in long-last...

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...

Imidazoline obtained from the essential oil contained in Pouteria sapota seed was tested as an environmentally-friendly corrosion inhibitor of 1018 carbon steel CO2 saturated 3.5 % NaCl solution using electrochemical techniques. This imidazoline contains fatty acids with presence long hydrophobic chains, 52.73 unsaturated (oleic and linolenic acids) 40 (palmitic myristic compounds. Polarization...

one of the problems in the case of stainless steels is their low corrosion resistance against pitting corrosionin chloride containing environments, thereby leading to severe damage to industries. in this research, the pitting corrosion of 304 austenitic stainless steel was studied in 3.5% nacl solution at room temperature (25˚c) by performing electrochemical measurements (containing cyclic pola...

Nafion contamination by ferrous-alloy corrosion products, resulting in dramatic drops of the Ohmic potential, is a suspected major failure mode of polymer electrolyte membrane fuel cells that make use of metallic bipolar plates. This study demonstrates the potential of scanning transmission X-ray microscopy combined with X-ray absorption and fluorescence microspectroscopy for exploring corrosio...
