In this study, the influence of biofilm on electrochemical behavior and corrosion resistance...

...Nicolas Larché; Charles Leballeur; Sandra Le Manchet; Wenle He Chlorination is widely used in seawater systems to avoid fouling and associated microbial-induced corrosion. Free chlorine is a strong oxidizing agent that prevents biofilm formation on immersed surfaces when used above a certain...

...Narasi Sridhar This paper reviews the localized corrosion of passive Ni-Fe-Cr-Mo-N alloys immersed in seawater using a Bayesian network (BN) method. Making alloy performance decisions using data from the literature on seawater is challenging because a large body of data is generated using various...

...Roger Francis; Glenn Byrne Austenitic cast iron has been used for many years for pump cases, column pipes, and valves in seawater systems, particularly in the Middle East. Since the 1970s, failures have occurred by stress corrosion cracking, and there have been a number of research efforts...

These are potential, temperature, dissolved oxygen content, biofilm and fouling activity, hydrostatic pressure, and calcareous deposit formation...

...-active” and “weakly-active” biological activity. Under cathodic control, a high current density was measured on stainless steel in deep seawater. The experimental setup used is particularly relevant as it allows determination in situ of the maximal cathodic current density...

... seawater The duplex castings are also substantially stronger than the cast austenitic alloys. This means there is scope for significant wall thickness savings as with wrought alloys. Duplex castings are also much more resistant to hot tearing than are fully austenitic castings, and therefore...
