Corrosion is a major cause of structural deterioration in the marine/offshore industry. FOr that reason, reliability assessment and maintenance planning of these structures are crucial. In the current work a combination multi-phase phenomenological and mechanistic model for pitting corrosion is tested using Bayesian network (BN) approach.
Investigation and comparison of effects of mineral wool and a water repellent insulation on CUI. Drain holes and their ability to reduce CUI was evaluated. The susceptibility to CUI of carbon steel was investigated at 80 °C using a newly developed test rig in a controlled environment (25 °C and 50 %RH).
The Hanford Site in Richland, WA stores liquid radioactive waste in underground, carbon steel tanks. Electrochemical corrosion testing was performed to determine new limits that optimize the chemistry control, yet are robust enough to inhibit against the possibility of increased concentrations of aggressive species.
Samples simulating the continuous changing structures of UNS S30400 heat affected zone (HAZ) were prepared for examination using metallographic structural analysis, corrosion morphological observations, and traditional electrochemical measurements to characterize the intergranular corrosion and pitting resistance.
