... is performed to correlate the surface and bulk composition and structure of application relevant alloys to the initial carbon formation and the progress towards metal dusting. UNS N08800 alloy coupons were prepared, polished and oxidized in diluted steam at 540 °C. Formation of carbon on the surface of the pre...

... ABSTRACT A combination of carbon and stainless steel probes and coupons was used to evaluate microbiologically influenced corrosion (MIC) in humid air and determine whether dry storage systems (DSSs) could be affected by MIC during extended storage. The material was exposed to several test...

... Abstract Surface protection in high temperature hydrogen sulfide environment remains a significant challenge with limited number of materials providing adequate protection. Diamond-like carbon (DLC) thin films are recognized across different sectors as a promising way of controlling wear...

... had a low carbon with high delta-ferrite content and the other of which had a high carbon content and no delta-ferrite. The DL-EPR process could detect the delta-ferrite in the low carbon material and also isolate DL-EPR degree of sensitization measurements to the HAZ of the high carbon material...

... ABSTRACT Topography and phase composition of the scales formed on in-house experimental low Si and Al ferritic stainless steel in simulated coal synthetic gas were investigated towards the carbon-induced corrosion study of ferritic steels for atmospheric and pressurized integrated gasification...

...-Microscope was used. Also the EDS analysis was applied for identification of phases in samples' structure. Moreover, the variation of the carbon concentration in the direction of the samples thickness was studied. The studies showed that the steels which have more chromium and nickel, are more resistant...

... was transported there during the regeneration cycle.) Samples of the powder were collected and analyzed, using multiple analytical techniques, and the composition is described as carbon (amorphous and meta anthracite), along with iron oxides (predominately Fe3O4 and Fe2O3) and cementite (Fe3C), with little...

This reaction denudes the metal adjacent to the grain boundary of chromium, one of the key elements in the corrosion resistance of the material. As a result, intergranular...

... of heavy carburization mainly at the outlet end has been attributed to increased throughput, higher tube temperature, and cracking of Tri-chloro Ethylene (TCE) and hydrocarbon. The active carbon formed as a result of cracking diffuses readily in steel at high temperature causing carburization of the tubes...

... ABSTRACT A new concept to inhibit Metal Dusting on the catalytically active surface of steel based on the application of tin was investigated. The target of this investigation is to reduce the affinity of high alloy steel surfaces towards carbon deposition and uptake in general. To avoid...

As of July 2008, Alloy N 10276 was $12/lb. Table 1 shows how the cost of N 10276 clad carbon steel compared to FRP. In this paper...

... and a high carbon activity. In the temperature regime above 550°C the thermal equilibrium between H2O, CO2 and Fe reacted and formed CO. CO triggers the formation of FeO and carbides and increases the reaction kinetics. Porosity at the interface is established by gaseous phases such as Fe(OH) or H O. H2 2 2...
