Electrochemical Corrosion Behavior of Nanocrystalline Materials—a Review

Journal of Materials Science and Technology, 2010
Nanocrystallization significantly influences the electrochemical corrosion behaviors of metals/alloys in liquid system. In active dissolution, nanocrystallization accelerates the corrosion reactions. If the corrosion products are dissoluble, the corrosion rate is increased by nanocrystallization; if the corrosion products are insoluble, the corrosion ...

Corrosion Failure and Electrochemical Corrosion Behavior of Coiled Tubing

Journal of Failure Analysis and Prevention, 2020
Coiled tubing (CT) is known to be susceptible to corrosion due to the complexity of wellbore environment and limited material selection. Since the weld seam (WS) and the base metal (BM) of CT are different in composition and microstructure, WS material usually shows very different (lower) corrosion resistance compared with BM.

Electrochemical Corrosion Behavior of AA7003

Materials Performance, 2018
The electrochemical corrosion behavior of 7003 aluminum alloy (AA7003) under peak aging (PA), double peak aging (DPA), and regression re-aging (RRA) in sodium chloride (NaCl) solution at different temperatures have been studied by using potentiodynamic polarization and electrochemical impedance spectroscopy tests in combination with scanning electron ...

Electrochemical and Corrosion Behaviors of Mild Steel Coated with Polypyrrole

Materials Science, 2003
Polypyrrole films are formed on low-carbon steel by electropolymerization in solutions of oxalic acid. Their morphology and corrosion properties are studied by the methods of scanning electron microscopy and dc polarization. Polypyrrole coatings increase the corrosion potentials and decrease the corrosion currents in neutral solutions of chlorides and ...

Electrochemical corrosion behavior of steel wires in a coalmine with a corrosive medium

Mining Science and Technology (China), 2011
Abstract A 6 × 19 point-contact hoisting cable was used as our research object to examine the progress of corrosion of steel wires in a laboratory, simulating the actual working conditions in a coalmine. An electrochemical method was used to investigate the corrosion behavior of steel wires with different surface treatments of a corrosive acid ...

Electrochemical corrosion behaviors of a-C:H and a-C:NX:H films

Applied Surface Science, 2008
Abstract The a-C:H and a-C:N X :H films were deposited onto silicon wafers using radio frequency (rf) plasma enhanced chemical vapor deposition (PECVD) and pulsed-dc glow discharge plasma CVD, respectively. Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) were used to characterize chemical nature and bond types of the films.

The Electrochemical Corrosion Behavior of HVOF Sprayed Coatings

International Thermal Spray Conference, 2000
Abstract Thermal spraying of corrosion resistant alloys onto low alloy steel substrates has received much attention as a method to protect against corrosion in seawater or corrosive solutions, such as mineral or organic acids. The need to ensure high coating quality with minimal porosity and cracking, and with low oxide levels is best ...

Corrosion and Electrochemical Behavior of In and In-Bi Alloys in HCl

Corrosion, 1985
The corrosion of In-Bi alloys in HCl was studied using x-ray, scanning electron microscopy, atomic absorption spectroscopy, and cyclic voltammetry techniques. In deaerated 3N HCl solutions, the selective dissolution of indium was the predominant mechanism in the corrosion of In-Bi alloys.

Corrosion and Electrochemical Behavior of Boron/Aluminum Composites

Corrosion, 1977
Electrochemical measurements in 3.5% NaCl solution at room temperature indicated that there was no galvanic interaction when virgin boron fibers were coupled to aluminum. In contrast, boron fibers, extracted from a boron/aluminum composite, containing an aluminum boride intermetallic on the surface (produced during high temperature fabrication), showed
