Editorial on oxidation in complex atmospheres
Résumé
The atmospheres surrounding metal parts in many industrial processes rarely comprise a single oxidant. Whether in fossil energy conversion plants, nuclear power plants, jet engines, chemical or petrochemical production routes, several molecules, sometimes present as main components, sometimes at the impurity level, play a role in corrosion mechanisms. Current research into the development of low-emission technologies also clearly demonstrates the importance of considering, in addition to O 2 , the effects of H 2 , H 2 O, NH 3 , etc. in the development and selection of alloys This collection of papers considers many situations where oxidation competes
with, for example, carburizing, nitriding, and sulfdizing reactions and where water vapor can have a signifcant impact in cases where, at frst glance, it would not even be considered. The papers include studies on the efect of H2 and/or H2O on pure titanium, on chromia scale, but also the benefts of alumina-forming alloys for many complex environments, as well as the subtle efect of Mn and Fe on the metal dusting resistance of NiCu alloys, highlighting the relevant assistance of thermodynamic
and ab initio calculation to address these complex corrosion issues. The following papers are contributions from the “Oxidation in Complex Atmospheres” session of the 11th International Conference on High-Temperature Corrosion and Protection of Materials (HTCPM 2024), held at Les Embiez Island, France, on 9–14 June 2024
