TIGRAL
TIGRAL – Abrasion resistance and high thermal resistivity
This coating, based on AlCrTiN, is characterised by its high hot hardness and its resistance towards oxidation and abrasion. These properties are the result of its nanostructure, which minimizes crack propagation within the coating, especially when subjected to shear loads.
