Woodhead Publishing Corrosion by Carbon and Nitrogen: Metal Dusting, Carburisation and Nitridation (EFC 41): Volume 41 (European Federation of Corrosion (EFC) Series, Volume 41)

Metal dusting is a form of corrosion involving the disintegration of metals and alloys into a dust of graphite and metal particles when exposed to a carburizing atmosphere. This important book reviews the factors affecting metal dusting and how it can be prevented in sectors such as the chemical and petrochemical industries and in the direct reduction of iron ores. It also considers the related corrosion phenomena of carburization and nitridation. Key Features: reviews this corrosion process and how it affects the petrochemical and other industries; discusses the effect of particular gas mixtures on the corrosion process. Contents: Metal dusting; The metal dusting corrosion of steels with varying concentrations of chromium; Microprocesses of metal dusting on iron-nickel alloys and their dependence on the alloy composition; Metal dusting behaviour of welded ni-base alloys with different surface finish; Effect of H2S on metal dusting of iron; Occurrence of metal dusting referring to failure cases; Protective behaviour of newly developed coatings against metal dusting; Metal dusting resistance of high chromium alloys; Study of the metal dusting behaviour of high-temperature alloys; Metal dusting of ferritic Fe-Al-M-C (M = Ti, V, Nb, Ta) alloys in CO-H2-H2O gas mixtures at 650 °C; a-Fe layer formation during metal dusting of iron in CO-H2-H2O gas mixtures; Coke formation during metal dusting of iron in CO-H2-H2O gas with high CO content; Morphologies and mechanisms of metal dusting on high alloy steels; Filamentous carbon formation caused by catalytic metal particles from iron oxide; Typical failures in pyrolysis coils for ethylene cracking; Thermodynamic characteristics and numerical modelling of internal nitridation of nickel base alloys; Nitridation in NH3-H2O-mixtures.
