Failure analysis of stainless steel tubes in a recuperator due to elevated temperature sulphur corrosion

Numerically predicted J-integral as a measure of crack driving force for steels 1.7147 and 1.4762

“…Here, the novelty of the research lies in numerically predicted values of the J-integral taken as a measure of the crack driving force for steels 1.7147 and 1.4762 which are, according to the authors' knowledge, unavailable to construction designers in the presented form. Both materials offer improved corrosion resistance and can be considered for engineering applications intended to be used in corrosive environment and susceptible to crack growth and fracture like spiral bevel gears in truck differential systems prone to failure (Sekercioglu and Kovan, 2007) or stainless steel tubes found in recuperators and exposed to elevated temperatures that cause failures (Bhattacharyya et al, 2008). The results of the investigation presented in this paper can be used to avoid such failure scenarios.…”

Synthesis and characterization of fluorinated organic–inorganic hybrid coatings on tinplate

“…Then, tinplate would lose its shiny appearance and excellent properties. 3 Thus, corrosion protection of tinplate is needed.…”

Corrosion Resistant Coatings Based on Organic-Inorganic Hybrids Reinforced by Carbon Nanotubes

“…The corrosion resistance is strongly weakened when metallic materials are subjected to a medium containing chloride or moisture environment, with a tendency to suffer localized corrosion. This may result result in the loss of aesthetic appearance and structural integrity, and can be accompanied by the release of potentially toxic ions, which can be hindered by protective coating (Tsutsumi at al., 2007;Bhattacharyya et al, 2008;Lopez at al., 2008;De Graeve at al., 2007). The most common corrosion prevention method is the hexavalent chromium-conversion, which forms insoluble trivalent chromium products by metal dissolution followed by precipitation of a passive layer of corrosion product.…”
