Fracture properties of CrN hard coatings: Influence of the microstructure, alloying elements, and coating architecture

Conference Dates

October 2 – 7, 2022


Transition metal nitrides are well known and applied as protective coating materials based on their unique refractory characteristics, such as high hardness or Young’s modulus. However, for long-term applications, the fracture toughness KIC is an essential factor as the integrity of the coating-substrate interface is impaired by cracking and subsequent environmental attacks.
