Molecular hydr ogen:An abundant energy source for bacterial activity in nuclear waste repositories. Comparison of Biocorrosion due to Desulfovibrio One observes several species of sulfate-reducing bacteria in nature. Presence of these species in a media may cause microbial influenced corrosion (MIC) of materials differently. To investigate this aspect of MIC, corrosion tests were performed on three types of stainless steels.

Corrosion of carbon steel under sequential aerobic Nov 01, 2013 · According to SEM-EDX, Raman and XRD analyses of steel corrosion products under different conditions, we can summarise the mechanism of steel corrosion in Fig. 11. Download :Download full-size image; Fig. 11. A physical mechanism of steel corrosion occurring at sequential aerobicanaerobic conditions at 30 °C. Evaluation of the risk of biocorrosion on a transit gas The goal of this work was to monitor selected factors important in terms of corrosion or bio-corrosion, namely location, soil and the presence of water in four parts of the transit gas line passing through Slovakia, and subsequently to identify the level of risk of bio-corrosion.

Impact of Iron-Reducing Bacteria on the Corrosion Rate of

Microbiologically influenced corrosion of ferritic steelzirconium-based metal waste form alloy under simulated geological repository environment. Corrosion Engineering, Science and Technology 2018, 53 (5) , 340-347. DOI:10.1080/1478422X.2018.1470397. Microbial corrosion of P235GH steel under geological The corrosion rate of the steel coupons was high under biotic conditions (not, vert, similar30 m/year) in comparison to blank sterilized runs (not, vert, similar14 m/year). Culture experiments in compacted conditions with claystone cores and steel coupons under 120 bar, simulating deep geological conditions, gave results similar to those Microbially influenced corrosion of carbon steel in the Assessment of canister material corrosion through microbial activity is an important part of the safety assessment for the final repository. The aim of study was to compare and characterise the corrosion behaviour of carbon steel under sterile and non-sterile anaerobic conditions in natural groundwater containing sulphate-reducing bacteria (SRB).

The Corrosion Behavior of Carbon Steel in Sulfide Aqueous Jan 31, 2014 · In this paper, we studied the effect of sulfide ions on the corrosion behavior of carbon steel to simulate the geological disposal of high-level radioactive waste. In geological storage conditions, sulfidogenic environment was sustained by sulfate-reducing bacteria. Corrosion tests were conducted in systems in a controlled atmosphere of 5% H 2 Microbial corrosion of P235GH steel under geological The corrosion rate of the steel coupons was high under biotic conditions (30 m/year) in comparison to blank sterilized runs (14 m/year). Culture experiments in compacted conditions with clay-stone cores and steel coupons under 120 bar, simulating deep geological conditions, gave results similar to those obtained in batch experiments
