Polar steel requires excellent toughness and corrosion resistance for breaking icy surfaces in low-temperature seawater environments. In this study, the effect of inclusions on polar was examined. experiments conducted, composition morphology were controlled using different deoxidation methods during refining. The corrosion-resistant active analyzed scanning electron microscopy energy dispersiv...

Corrosive sulfur and the effect that it has in transformer systems can be significant. The extent of the corrosion damage caused by sulfur, if left unchecked, can be so severe as to cause failure of the apparatus. The problems with corrosive sulfur have been recognized for quite some time. As early as 1948, F.M. Clark and E.L. Raab [1] issued a report on the subject for method development withi...

as an alternative to chromate conversion coatings, rare-earth coatings especially cerium, because of the low toxicity, have attracted considerable attention. using dip immersion method, cerium-based conversion coating was deposited on aluminum 2024. corrosion resistance was studied in 3.5 wt.% nacl solution using potentiodynamic polarization, electrochemical impedance spectroscopy, and surface ...

BACKGROUND Corrosive esophageal burns, particularly common in developing countries, lead to different problems in different age groups. The ingestion of corrosive substances can cause such problems as stricture of the esophagus, to acute perforation, and even death. Because stricture formation is related to the severity of the initial injury, the prevention of stricture constitutes a main goal ...

Atmospheric corrosion occurs under alternate cycles in presence and absence of an electrolyte layer, the severity of corrosion processes that occur onto the metallic surface depends largely on the corrosive environment to which the material is exposed. Whereas the corrosive phenomena occur in the presence of the electrolyte, in this work the effect of the depth of the solution layer on the elec...

Materials used in the target for accelerator-driven transmutation systems (ADS) will be subject to extreme temperatures and corrosive environments. The mechanical properties such as the yield strength and ductility parameters, for most candidate materials have yet to be evaluated under these conditions. Martensitic alloy EP-823, a leading candidate target structural material for use in ADS appl...
