TL;DR: In this article, chemical composition, crystal structure and mechanical properties like hardness, wear rate and film stress are characterized for Al1−xCrxN films with various composition by the reactive cathodic arc process.

TL;DR: In this paper, the structure of the well adherent coatings was investigated by X-ray diffraction and Raman spectroscopy, which indicated at higher Al/Cr ratio > 1.9 an increased tendency of the metastable face-centered cubic solid solution of AlN in CrN to separate into a cubic-hexagonal phase mixture.

TL;DR: In this paper, V-alloyed AlCrN hard coatings were deposited by reactive arc-evaporation in a commercial Balzers RCS coating system, which resulted in a reduction of hardness from 28 to 19 GPa and biaxial coating stress.

TL;DR: In this paper, the authors demonstrate that it is possible to increase fracture toughness by a dedicated grain boundary orientation with respect to the direction of the expected crack path without loss of hardness.

TL;DR: In this article, the response of TiAlTaN droplets to tribological loading and their contribution to the tribological system was investigated, and it was found that droplets contribute to coating degradation by providing nucleation sites for shear cracks and by the release of abrasive fragments into the sliding contact.
