Critical characteristics of corrosion product film obtained by fluid structure interaction

Materials and Corrosion - Werkstoffe Und Korrosion, 2013
AbstractThe critical characteristics of corrosion product film (CPF) were investigated, and the mechanism of flow‐accelerated corrosion (FAC) was discussed by improving the multiple reference frame method (MRF) using the space temporary coordinate system. The improved MRF was used to accomplish fluid structure interaction (FSI) numerical simulation for

Atomistic Insights into the Deposition of Corrosion Products on the Surfaces of Steels and Passivation Films

Langmuir, 2023
The deposition of corrosion products on the surface of the steel is a key step for understanding the generation of corrosion products. To clarify the molecular mechanism for corrosion product deposition, the reactive molecular dynamics were utilized to study the deposition process of ferric hydroxide (Fe(OH)3) on iron and passivation film substrates ...

The growth mechanism of CO2 corrosion product films

Corrosion Science, 2011
Abstract Carbon steel usually has high corrosion rate in water with dissolved CO2 however the steel surface can be covered by protective corrosion product film. Therefore the carbon steel can be widely used in oil and gas industry. This paper discusses the structure, electrochemistry performances, initiation and growth of protective corrosion product

Thermodynamic Prediction of FeCO3/FeS Corrosion Product Films

CORROSION 2011, 2011
Abstract Oil and gas production facilities transport a wide range of fluids which may contain carbon dioxide (CO2), hydrogen sulfide (H2S) and many other species that may lead to a corrosive environment. To ensure safe and cost effective production operations it is important to understand the combined effect of H2S and CO2 on corrosion ...

Identification of Passive Films and Corrosion Products

2017
The products resulting from corrosion reactions consist of various compounds with a thickness from a few nm to several 100 μm. For in situ detection of them under the corrosion environment, optical techniques using light from ultraviolet (UV) to infrared (IR) have been applied such as reflection of ellipsometry and differential reflectance, molecular ...

Analysis of corrosion products beneath an epoxy-amine varnish film

Progress in Organic Coatings, 2002
In situ Raman analysis was applied to identify the corrosion products formed on iron coated with epoxy-amine varnish and exposed to sodium chloride solution saturated by hydrogen sulfide or carbon dioxide. The results showed the formation of iron sulfide or iron carbonate layer while electrochemical impedance spectrum predicted the polymer coating ...

The Impact of Temperature on CO2 Corrosion and the Formation of Corrosion Product Film

Corrosion
The impact of temperature on CO2 corrosion was investigated by weight loss, in situ electrochemical measurements, and characterization of corrosion product film. The results showed that with the increase of temperature, corrosion rate decreased remarkably, which can be ascribed to different product films formed on metal surfaces.
