Automated Monitoring of Metal Corrosion for Water Delivery Infrastructure
The real-time corrosion rate of mild steel in drinking water and the properties of that water are measured and recorded in time using a newly build computed automated system. A non-destructive electrochemical method is used to find the corrosion rate (CR) of mild steel coupons in time and these are …

Diffusion Barrier Coatings for Liquid Metal Corrosion Resistance in Next-Generation Nuclear Reactors
… applied onto nuclear reactor cladding, liquid metal coolants, and metallic fuel used in Sodium-Cooled Fast Reactors (SFRs) and Lead-Cooled Fast Reactors (LFRs). In SFRs and LFRs, damage to cladding and structural materials from the liquid metal coolant poses large issues for reactor safety and …

In-situ early detection of metal corrosion via "turn-on" fluorescence in "smart" epoxy coatings
… epoxy coatings) have been widely used to protect metal and metal alloys against corrosion. However protective coating fails with time, leading to corrosion of the metal substrate. When localized corrosion occurs, without being detected, it can result in disastrous failure of the metal structure. …

Study on the fundamental causes of metal corrosion in animal buildings: Field and chamber tests
This thesis discusses in detail the corrosion mechanisms of metal products exposed for a period of two years in three animal buildings and one environmentally controlled building based on the analyses of the surface corrosion products using advanced surface analysis techniques. It includes not only …

The Effect of Spill Contaminants on Marine Biofilms and Microbially-Induced Corrosion of Carbon Steel
… on the seafloor. Oil potentially accelerates corrosion of metal through a biologically-mediated process called microbially-induced corrosion (MIC). Introduction of spill contaminants may accelerate MIC on shipwreck hulls, which may place the integrity of historic shipwrecks at risk. The …

The systematic study of corrosion and oxygen control by chemical scavenging agents
Corrosion of metal components in electrical power generation boilers is a serious and expensive problem that is a major concern to manufacturers and electrical utility personnel. Lost production and large costs associated with component failures have created a tremendous research effort to help …

Corrosion detection using metal coatings on fiber optic sensors
Fiber optic sensors have been utilized as corrosion sensors by depositing metal coatings to the surface of the sensors. Three types of fiber optic sensors were investigated as candidates for corrosion detection: the extrinsic Fabry-Perot interferometer (EFPI), the absolute extrinsic Fabry-Perot …

Study of Titanium based Composite Coatings for Resistance against Molten Aluminium Soldering on H13 Tool Steel
… components is limited predominantly by chemical corrosion, mechanical failure or mechanical wear. In the aluminium high pressure die casting industry, liquid aluminium is extremely reactive with the constituents of H13 die steel and has a tendency to form intermetallic layers. This chemical …

Experimental simulation of crevice corrosion of a functionally graded composite system of F91 and Fe-12Cr-2Si exposed to high-temperature lead-bismuth eutectic coolant
In a system in which metal corrosion is of concern to its long-term structural integrity, crevice corrosion can be a significant cause of damage. Small crevices in a metal exposed to a working fluid (such as a reactor's coolant) may be prone to the development of a localized, aggressive reducing …

Real time nanogravimetric monitoring of corrosion in radioactive environments
Monitoring and understanding the mechanism of metal corrosion throughout the nuclear fuel cycle play a key role in the safe asset management of facilities. They also provide information essential for making an informed choice regarding the selection of decontamination methods for steel plant and …

In situ Nanoscale Quantification of Corrosion Kinetics by Quantitative Phase Microscopy
Corrosion-related degradation incurs a significant cost to infrastructure and society. In 2016, the direct corrosion cost was estimated at $276 billion, which is 3.1% of the U.S. gross domestic product. Despite the known consequences of corrosion damage, many unknowns still exist, such as the …
