A THERMODINAMIC CORROSION STUDY OF CARBON STEELS IN HYDROGEN SULFIDE - EXPLORING CHEMICAL EQUILIBRIUM CONCEPTS
(Soc Brasileira Quimica, 2018-05-01)
This study addresses an inherent problem to the oil and natural gas exploration and production industry, the corrosion of pipes and tanks by H2S. H2S with water emulsified in the oil or H2S with the water vapor mixed in ...
Corrosion protection of steel by volatile corrosion inhibitors: Vapor analysis by gas-diffusion microextraction and mass loss and electrochemical impedance in nacl deliquescence tests
(2020-10-01)
A new methodology using gas-diffusion microextraction (GDME) was developed for the analysis of volatile corrosion inhibitors (VCIs). The evaluation of the inhibition efficiency and corrosion rate (ν) was performed by NaCl ...
Corrosion Behavior and Microstructural Characterization of Friction Stir Welded API X70 Steel
(2021-01-01)
Friction stir welding (FSW) is an excellent alternative process used in pipelines circumferential welds due to fusion welded joint low corrosion resistance. This study describes the corrosion resistance as a function of ...
On the development of the electrochemical potentiokinetic method
(2001-08-15)
The development of electrochemical potentiokinetic methods as applied to the testing of metals and alloys is followed from its early phases up to its latest advances relating to intergranular corrosion, SCC and pitting ...
Influence of chromate, molybdate and tungstate on pit formation in chloride medium
(2005-11-15)
It has been characterized and evaluated the 2024-T351 and 7050-T7451 aluminum alloys pitting corrosion in naturally aerated chloride aqueous solutions containing chromate, molybdate and tungstate. It has been carried out ...
Corrosion effects on pullout behavior of hooked steel fibers in self-compacting concrete
(2016-01-01)
Fiber reinforced concrete structures are subjected to chloride and carbonation penetration that could initiate corrosion of steel fibers, with eventual pernicious consequences in terms of structural and durability performance. ...
Interstitial oxygen's influence on the corrosion behavior of Ti-9Mo alloys
(ABM, ABC, ABPol, 2013-12-01)
Titanium and its alloys have been used in biomedical applications because of their satisfactory mechanical properties, biocompatibility and corrosion resistance. Their high corrosion resistance has been attributed to the ...
