Investigation of Influence of Surface Roughness on Pitting Corrosion of Duplex Stainless Steel 2205 using Various Electrochemical Techniques

open access: yesInternational Journal of Electrochemical Science, 2019
The metastable and stable pitting behaviors on different surface roughness finishes for DSS 2205 stainless steel have been investigated. Surface roughness was analyzed through the adoption of atomic force microscopy (AFM).

Empirical propagation laws of intergranular corrosion defects affecting 2024 T351 alloy in chloride solutions [PDF]

open access: yes, 2010
In the present work, a first attempt was made to determine propagation laws of intergranular corrosion defects for Al 2024 T351 in various NaCl solutions as a first step for future predictive modeling of 2024 alloy.

Effect of Oxygen Content on Surface and Subsurface Integrity During Turning of Ti–6Al–4V

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how oxygen content in the ambient atmosphere affects the surface and subsurface properties of Ti–6Al–4V during turning. Results show that oxygen does not influence surface roughness. However, machining in an extremely high vacuum‐adequate atmosphere increases surface hardness by up to 7.8% and induces compressive residual stresses ...

Understanding the local pitting corrosion characteristics of carbon steel in CO2 corrosion environment using artificially machined pits

open access: yesResults in Engineering, 2022
Carbon steel remains the most commonly used material in CO2 – containing oilfield, and other energy applications. Pitting corrosion is a prominent form of corrosion attack on carbon steel, and linked to the formation of non – protective iron carbonate ...

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Effect of prolonged temperature exposure on pitting corrosion of duplex stainless steel weld joints

open access: yesAin Shams Engineering Journal, 2018
This study aimed at evaluating the pitting corrosion of duplex stainless steel (2205) welded by filler metal (2209) after exposure to increased service temperatures. In this work selected welded samples were aged at different temperatures (650 °C, 850 °C,

Bacteria have transient influences on marine corrosion of steel [PDF]

open access: yes, 2011
The contribution of bacteria to the corrosion mass loss and to pitting of mild steel was observed over 2.5 years using parallel streams of unpolluted natural (biotic) and nominally sterilized (abiotic) Pacific Ocean coastal seawater.

Contribution of cellular automata to the understanding of corrosion phenomena [PDF]

open access: yes, 2017
We present a stochastic CA modelling approach of corrosion based on spatially separated electrochemical half-reactions, diffusion, acido-basic neutralization in solution and passive properties of the oxide layers.

The influence of incorporation of Mn on the pitting corrosion performance of CrFeCoNi High Entropy Alloy at different temperatures

open access: yes, 2019
The electrochemical behavior and susceptibility to pitting corrosion of CrFeCoNi and CrMnFeCoNi high entropy alloys were studied in a 0.1 M NaCl solution at temperatures ranging from 25 to 75 °C.
