Blåmerkebildning
Blåmerkebildning, also known as blue mark formation, is a phenomenon observed in the field of materials science and engineering, particularly in the context of metal fatigue and corrosion. It refers to the formation of a distinctive blue or blue-gray discoloration on the surface of a material, typically a metal, as a result of fatigue or corrosion processes. This discoloration is often associated with the presence of certain chemical compounds or the alteration of the material's microstructure.
The blue mark formation is commonly observed in metals subjected to cyclic loading, such as in rotating
In addition to fatigue, blue mark formation can also occur as a result of corrosion processes. Corrosion
The study of blue mark formation is important for understanding the mechanisms of fatigue and corrosion, as
