Ability of Metallic Materials to Resist Surface Damage Induced by High-temperature Action of Air or other Gaseous Mediums
Abstract: The features of the oxide layer scale that forms on the metal's surface and limits gas penetration into the metal, limiting the growth of gaseous corrosion, influence a metal's or alloy's oxidation resistance in an oxidising atmosphere. The rise in weight of sample being tested (due to oxygen uptake by the metal) or even the weight loss after removing the scale from the sample's surface, related to a unit surface …
