atmosphereoxidizing
Atmosphereoxidizing, more commonly referred to as an oxidizing atmosphere, denotes a gas environment in which oxidizing species, primarily molecular oxygen, are present at sufficient partial pressure to drive oxidation of materials or chemical species. In industrial and laboratory settings, this term describes the atmospheric conditions surrounding processes such as heating, annealing, sintering, welding, and surface treatment. The critical parameter is the oxygen partial pressure (pO2), together with temperature and humidity, which together determine the thermodynamic stability of oxides and the rate of oxide formation.
Common sources of oxidizing atmospheres include ambient air, oxygen-enriched air, pure oxygen, and air with additional
Control and safety are important aspects of working with oxidizing atmospheres. Equipment often allows adjustment of
