Use of electrochemical current noise method to monitor carbon steel corrosion under mineral wool insulation.
In this investigation, we developed a method based on electrochemical current noise to detect the onset of corrosion under insulation, its intensity, and the predominant form of corrosion (i.e., uniform or localised).
Characterization of Intergranular Phases in Precipitation Hardening Ni Alloy UNS N07725
This paper demonstrates for the first time the formation of F phase in the nickel-alloy 725 (UNS N07725) at grain boundaries (GBs). F phase is a detrimental TCP phase that plays a key role on hydrogen embrittlement.
Use of the Critical Acidification Model to Estimate the Influence of W in the Localized Corrosion Resistance of 25 Cr Super Duplex Stainless Steels.
The results obtained in this work point at a beneficial role of W in a stable propagating attack at temperatures T > TR. Even though the mechanism cannot be inferred from the data gathered, the dissolution in the W-rich specimen was diminished significantly.
Crevice Corrosion of Solution Annealed 25Cr Duplex Stainless Steels: Effect of W on Critical Temperatures.
In this paper, we showed that tungsten, when added as a solid solution element, improved the crevice corrosion resistance of 25Cr super duplex stainless steels.
Microbiologically influenced corrosion as a function of environmental conditions: A laboratory study using oilfield multispecies biofilms
In this paper, it is demonstrated that microorganisms can trigger severe corrosion rates in the absence of sulphate.
The role of tungsten on the phase transformation kinetics and its correlation with the localized corrosion resistance of 25Cr super duplex stainless steels
This investigation demonstrated that tungsten drastically slowed the precipitation of deleterious tertiary phases down in 25Cr super duplex stainless steels, resulting in an improved overall pitting corrosion resistance.
Nutrient level determines biofilm characteristics and the subsequent impact on microbial corrosion and biocide effectiveness
This investigation demonstrated that the continuous flow of nutrients for the microbial growth resulted in higher activity, thickness and robustness of the biofilms formed on carbon steel, which induced greater localised corrosion compared to biofilms formed under batch, nutrient-depleted conditions.
Conversion of reference electrode potentials
The conversion of reference electrode scales is a simple process, yet it can be confusing. This article shows a simple method to help you avoid errors.
Complementary DNA/RNA-Based Profiling: Characterization of Corrosive Microbial Communities and Their Functional Profiles in an Oil Production Facility
In this investigation, it was showed that DNA-based sequencing results alone could lead to underestimation of active members in the community resulting in an inaccurate MIC risk assessment.
