Electrochemical Corrosion Tests in Low-Conductivity Ethanol–Gasoline Blends: Application of Supporting Electrolyte for Contaminated E5 and E10 Fuels

These modified EIS and TS corrosion measurements based on the use of tetrabutylammonium tetrafluoroborate at 500 mg/L as a supporting electrolyte present a significant extension of an electrochemical testing apparatus for steel corrosion studies in EGBs.



Conducting Electrochemical Measurements in Fuel-Grade Ethanol Using Microelectrodes

Abstract Corrosion and stress corrosion cracking of carbon steel in bio-fuels are a concern with the increase in the usage of ethanol as an alternate fuel. Electrochemical studies in highly resistive

Study of Corrosion of Metallic Materials in Ethanol–Gasoline Blends: Application of Electrochemical Methods

Ethanol–gasoline blends (EGBs) can easily absorb large amounts of water because of the presence of ethanol. Acidic compounds and ions can be dissolved in water, and these substances can have

Efficiency of Steel Corrosion Inhibitors in an Environment of Ethanol–Gasoline Blends

This study tested three different corrosion inhibitors on mild steel in the environment of aggressive E10, E25, E60, and E85 fuels to study the efficiency of the corrosion inhibitors and used static and dynamic corrosion tests and electrochemical measurements including impedance spectroscopy and potentiodynamic polarization.

Study of Corrosion Effects of Oxidized Ethanol–Gasoline Blends on Metallic Materials

Bioethanol added into gasolines significantly changes the physical and chemical properties of the resulting fuels and can have a considerable influence on their overall thermo-oxidative stability.

Supporting Electrolyte for Corrosion and Cracking Studies in Deaerated Simulated Fuel Grade Ethanol
