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 oxidizing 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 and the time of the experiment are the quantitative aspects of oxidation resistance. The surface state of the sample or component is taken into account at the same time; this may vary subjectively even though its quantitative qualities are the same. Oxidation resistance, like heat resistance, is a basic requirement for a material’s fitness for high-temperature use. For many applications, strong oxidizing resistance of hard composite coatings is just as crucial as thermal stability. The chemical nature of the film has a significant impact on its high-T oxidation resistance. The creation of a persistent, passive, void-free oxide layer on the film’s surface is a very effective method for improving high-T oxidation resistance. As a result, films with components that quickly produce oxides and stabilize amorphous phases have greater oxidation resistance. Recent experiments indicate that the value of Si in a film has a significant impact on its high-temperature oxidation durability. The structure of films has a significant impact on oxidation resistance. It is generally known that films with a little amount of additional components (less than 5%) have a well- developed columnar microstructure. These films have holes between columns that connect the film’s surface to the substrate directly. As a result, these films have a poorer oxidation resistance and significantly thicker oxide layers than films with a higher added element content.
