Increasing the sulfate ions content above, had an inhibition effect on the corrosion behavior of carbon steel. The highest corrosion rate was detected for electrolytes containing 0.5 M Na2SO4. Carbon steel corrosion induced by sulphate-reducing In this work, the corrosion behavior of carbon steel AISI 1020 was evaluated in artificial seawater in the presence of mixed sulfate-reducing bacteria (SRB) culture isolated from the rust of a pipeline. The corrosion evaluation was performed by electrochemical techniques

Corrosion of 907 Steel Influenced by Sulfate-Reducing

The effect of sulfate-reducing bacteria (SRB) on the corrosion of 907 steel was investigated. Results demonstrated that the chemical composition of corrosion products, the corrosion rate, and corrosion type were altered due to the adherence of SRB and the subsequent formation of biofilm on the 907 steel surface. Different from the case in sterile medium that ferrous oxides predominated in the Corrosion of Carbon Steel - Total MateriaCarbon steel, the most widely used engineering material, accounts for approximately 85%, of the annual steel production worldwide. Despite its relatively limited corrosion resistance, carbon steel is used in large tonnages in marine applications, nuclear power and fossil fuel power plants, transportation, chemical processing, petroleum production and refining, pipelines, mining, construction Corrosion of Carbon Steel - Total MateriaCarbon steel, the most widely used engineering material, accounts for approximately 85%, of the annual steel production worldwide.

Electrochemical Analysis of Carbon Steel Corrosion

While the effect of chlorides on reinforcing steel corrosion as well as the internal or external sulfate attack to the matrix of cementitious materials is well documented in the literature, the corrosion behavior of steels subjected to sulfate ions or concurrent existence of chloride and sulfate has been scarcely reported.

Liu, et al., Corrosion behavior of carbon steel in the presence of sulfate reducing bacteria and iron oxidizing bacteria cultured in oileld produced water, Corros. Influence of Sulfate-Reducing Bacteria on the Corrosion Sep 07, 2016 · I corr illustrates the corrosion behavior of steel on the free corrosion potential. The larger I corr (4.4059 A cm -2 ) at -0.85 V SCE than that at OCP (2.228 A cm -2 ) could be attributed to the enhanced SRB activity, while the smaller I corr (2.2128 A cm -2 ) at -1.05 V SCE than that at OCP (2.228 A cm -2 ) was caused by the

Microbiologically Influenced Corrosion of Carbon Steel

The corrosion mechanism of carbon steel under deposit in the presence of sulfate reducing bacterium (SRB) Desulfotomaculum nigrificans was studied using surface analysis, weight loss and electrochemical measurements. Results showed that both the general corrosion and localized corrosion were considerably promoted by SRB under deposit. The corrosion rate of steel in the presence of SRB Study of corrosion behavior and mechanism of carbon steel Dec 01, 2015 · In this paper, the corrosion behavior of Q235 carbon steel in the presence of Chlorella vulgaris (C. vulgaris) was investigated by surface analysis, weight loss and electrochemical measurements.Results showed that the average corrosion rate in the presence of C. vulgaris was approximately 4 times as high as that in the absence of C. vulgaris.The corrosion rate in the daytime Sulfate Limits for Corrosion of Steel Strand in Deficient Med Sulfate, Low Chloride Corrosion Behavior in Inverted Tee Test (INT) Combined Admixed Sulfate and Chloride The steel in deficient grout with combined presence of sulfates with low level chlorides had active corrosion potentials <-400mV SCE and current densities as high as 6 uA/cm2. Corrosion of steel in tee header typically with >~ 0.01 g

The influence of sulphatereducing bacteria on

Sep 28, 2015 · The presence of SRB in seawater results in the change of corrosion form of Q235 carbon steel from uniform corrosion to localized corrosion. Meanwhile, current distribution of Q235 carbon steel surface changes from homogeneity to heterogeneity in SRB medium, which is opposite to the trend in sterile medium.Research Article Corrosion Behavior of Carbon Steel in Corrosion mechanisms in oil eld systems are com- plex and are showing high degrees of interaction between corrosion species, products, and oil eld metallurgies. e interactions of sulfate and chloride are of interest in this work, since presence of sulfate ions, in oil eld produced water,stronglyin uencecorrosionmechanisms.Whilethere are many research works on the e ects of
