“…4). These lower measured potentials of A. fulgidus-inoculated media correspond to an accelerated corrosion process (Venzlaff et al, 2013;Wu et al, 2015;Raman et al, 2008;Cheng et al, 2009;Alfaro-Cuevas-Villanueva et al, 2006), confirmed by our measured current densities. It could be related to intense microbial activity (Cheng et al, 2009) and correlated to the SEM and AFM observations (Figs.…”

This work assessed the role of the hyperthermophilic sulfate-reducing archaeon, Archaeoglobus fulgidus in anaerobic iron corrosion, at 70 • C, in the presence and the absence of lactate as energy source. Experiments performed with A. fulgidus planktonic cells, displayed their capacity to form a biofilm on an iron coupon and exhibited their biocorrosive activity. A. fulgidus was shown to cause indirect corrosion by producing sulfide while oxidizing lactate. Furthermore, the archaeon could grow lithotrophically by using elemental iron as a mineral energy source. Under these latter conditions, A. fulgidus formed chimneys enhancing the direct corrosion process. Moreover, physiological modifications occurred under these conditions notably highlighting the probable use of CO 2 instead of sulfate as a terminal electron acceptor to produce acetate similarly to homoacetogens. All together, these results illustrate the metabolic versatility and hence the importance of this hyperthermophilic archaeon in microbial induced corrosion (MIC).

“…As a result, during the fretting wear process, abrasion is not the only damage, microstructure changes, including nano-grain layer, deformation slips with high residual strain concentration and even micro-cracks will also have a detrimental effect to the service performance of the heat exchanger tubes in NPPs. For instance, high residual strain concentration and deformation slips will promote the SCC or fatigue initiation and propagation in nickel-based alloys and stainless steels in HTHP water [36,37].…”

In pressurized water reactor, fretting corrosion has become the main reason for the failure of 690TT heat exchanger tubes. The effect of temperature on the fretting corrosion behavior between 690TT tube and 405 stainless steel (SS) bar has been studied during 10 6 fretting cycles. The overall average coefficient of friction (COF) values descends with an increase in test temperature, while the width of worn scar becomes wider. The severest fretting corrosion happens when the test temperature is at 100 °C. The wear mechanism differs at different test temperatures, from adhesive wear at room temperature to abrasive wear and delamination at 100 °C, to abrasive wear at 200 °C. Deformation slips, high residual strain concentration, and micro-cracks are found which are disadvantageous for the further service performance of the tubes.

“…Sulfate-reducing bacteria (SRB) are anaerobic bacteria, which can be found in 1 3 oxygen-deficient soils. SRB can increase the corrosion process by producing hydrogen sulfide and transform non-corrosive soil into highly corrosive soil [8]. Li et al [9] found that Brevibacterium halotolerans promote the corrosion of X80 steel.…”

The influence of pH and metallographic structure on the corrosion behavior of copper-drawn steel is studied with the simulated system. The effect of pH on the corrosion behavior of copper-drawn steel has been investigated using open-circuit potential, potentiodynamic polarization, galvanic current measurement, scanning electron microscopy and scanning vibrating electrode technique techniques. The steel is corroded as anode, while the corrosion of copper plate is protected as cathode. All the results revealed that pH and metallographic structure had a significant influence on the corrosion behavior of copper-drawn steel. With the decrease in pH value from 6 to 2.4, the corrosion rate of copper-drawn steel galvanic couple (Cu-Fe GC) obviously increased in the simulated solution of acidic red soil. The electric field formed by the Cu-Fe GC changes the direction of ion migration between the copper and drawn steel electrodes, which impacts the composition and microstructure of corrosion products formed on the electrode surface.
