...Abstract Connection points on steel structures are often distinguished as critical areas of concern for infrastructure and mechanical failure. Although fasteners are an integral piece in structural integrity, these components are ranked as one of the most frequent points of corrosion caused...

...Reinforced concrete and steel, the two primary construction materials for bridges, have a heavy environmental footprint and both can fail prematurely from corrosion. Extending the lives of existing bridge structures reduces the total cost of ownership of a bridge, but also reduces the mining...

... to a variety of other exposure sites around the world. Atmospheric corrosion barge bridge accelerated testing environmental severity steel infrastructure INTRODUCTION Proper design of infrastructure like bridges, roadways, power grids, pipelines, etc. require corrosion performance assessment...

...Abstract Steel can be susceptible to corrosion, the natural process by which metals degrade. Combining coatings such as polyurethanes, epoxies, and wrap sleeves, with a cathodic protection system provides an effective strategy for protecting and extending the design life of your asset. corrosion...

...Abstract Hydrogen Stress Cracking (HSC) of steels and CRA has been studied for a long time and it is recognized that the results have significant variability depending on many factors, including test procedures, material microstructures, and environmental variables. Although the standards used...

... of electrocoated steel. Different electrocoats were ranked based on their performance in cyclic cabinet tests, full immersion in NaCl, or by accelerated electrochemical methods. Finally, the trends observed in corrosion behavior were compared, and conclusions were drawn based on the mechanisms captured...

...Hydrogen permeation barrier coatings are being considered as a low-cost solution to help pivot this existing transmission and distribution network to handle high pressure hydrogen [ 9 , 10 ]. Barrier coatings, in principle, prevent the ingress of atomic hydrogen into the pipeline steel, which...

...Abstract Stainless steels such as grade 316 are commonly used in various hydrogen applications, and the hydrogen embrittlement (HE) resistance of these steels is well-established. However, the high degree of alloying, particularly nickel, required to achieve the stable austenitic microstructure...

... chemisorb on Fe (001) surface through Fe—C and Fe—O bonds. Steel Corrosion Inhibitor Density Functional Theory Adsorption Interfaces INTRODUCTION Corrosion of metals and their alloys has been a major problem for industries. ¹ As per a NACE impact study, the annual cost of corrosion...

..., and interaction between the inhibitor molecule and the passive layer developed on C1018 carbon steel were compared experimentally. Corrosion models predicted that this passivating layer comprises primarily magnetite (Fe₃O₄), and surface scans showed that this passivating layer forms without...

... and stainless steels under transportation and storage conditions at temperatures < 80 °C, which is much lower than the FCC feeding temperatures of 100–300 °C. In this work, the thermal stability and corrosivity of pinewood-derived bio-oil were evaluated by aging at 150 °C and immersion experiments...

...supercritical carbon dioxide O₂ H₂O steel chromium Abstract In advanced power generation systems, the supercritical CO₂ (s-CO₂) Brayton cycle has been developed as a promising technology because of its high efficiency, compactness, and potential...

...Corrosion of galvanized steel subjected to wetting in chloride environments develops in three distinct stages. ^{4 - 8} The initial stage involves the dissolution of zinc to oxides characterized by fast oxidation rates and a shift of the open-circuit potential from its early...
