“…According to Barnett et al (Ref 43), the difference in layer elastic modulus is an important factor in determining the hardness improvement. In addition, there is a strong relationship between the nature of interface and the enhancement in hardness ( Ref 44,45). Indeed, smooth and sharp interface can block the movement of dislocations and then promotes the enhancement of the hardness.…”

CrN/CrAlN thin films were deposited by DC reactive magnetron sputtering. The influence of CrN/CrAlN bilayer thickness on the microstructure, mechanical, and tribological properties was studied. Crystallinity of the layers was characterized by x-ray diffraction. The microstructure of all coatings was observed by scanning electron microscopy. Results exhibit that bilayer thickness was a dominant factor. The analyses showed a columnar microstructure for the CrN/CrAlN coatings. Owing to their denser structure and interfacial strengthening, CrN/CrAlN multilayer coatings exhibited higher mechanical properties than that of monolayers. Indeed, CrN/CrAlN multilayer coating with four bilayers and thickness gradient reaches a maximum of hardness around 43 GPa. Also, its resistance to spallation reaches 97 N which is a very excellent value. After ball-on-disk wear tests, it is found that all multilayer films exhibited a good wear resistance, especially the one with four bilayers and different CrN and CrAlN monolayers thickness. The lowest coefficient of friction is obtained for the coatings with 4 bilayers.

“…For the HfBx (x value is higher or lower than 2) coating deposited by radio frequencies magnetron sputtering (RFMS) [12][13][14], its crystallization could be adjusted from the amorphous, cluster, poor pronounced columnar to columnar, with the variation of bias voltage and temperature simultaneously [12]. The corresponding hardness can be increased from 13 GPa for the amorphous film to 44 GPa for the (001) preferred oriented film [12].…”
