“…Kutschej et al also reported high hardness for TiAlBN coatings exhibiting a completely hexagonal matrix lattice [18]. Since then, other groups have also reported good hardness and oxidation resistance results on TiAlBNbased coatings [19,20,21,22].…”

The microstructure, mechanical properties and thermal stability of Al x Ti 1− x N and Al 1 Ti 1-x BN coatings grown by reactive high-power impulse magnetron sputtering (HiPIMS) have been analyzed as a function of Al/(Al + Ti) ratio (x) between 0.5 and 0.8. The coatings were predominantly formed by a face-centered cubic Ti(Al)N crystalline phase, both with and without B, even for x ratios as high as 0.6, which is higher than the ratio typically encountered for Al x Ti 1− x N coatings deposited by reactive magnetron sputtering. B doping, in combination with the highly energetic deposition conditions offered by HiPIMS, results in the suppression of the columnar grain morphology typically encountered in Al x Ti 1− x N coatings. On the contrary, the Al x Ti 1− x BN coatings grown by HiPIMS present a dense nanocomposite type microstructure, formed by nanocrystalline Ti(Al) N domains and amorphous regions composed of Ti(Al)B 2 and BN. As a result, high-Al content (x ≈ 0.6) Al x-Ti 1− x BN coatings grown by HiPIMS offer higher hardness, elasticity and fracture toughness than Al x Ti 1− x N coatings. Moreover, the thermal stability and the hot hardness are substantially enhanced, delaying the onset of formation of the detrimental hexagonal AlN phase from 850 • C in the case of Al 0.6 Ti 0.4 N, to 1000 • C in the case of Al 0.6 Ti 0.4 BN.

The microstructure, mechanical properties and thermal stability of Al x Ti 1−x N and Al 1−x Ti x BN coatings grown by reactive high-power impulse magnetron sputtering (HiPIMS) have been analyzed as a function of Al/(Al + T i) ratio (x) between 0.5 and 0.8. The coatings were predominantly formed by a face-centered cubic Ti(Al)N crystalline phase, both with and without B, even for x ratios as high as 0.6, which is higher than the ratio typically encountered for Al x Ti 1−x N coatings deposited by reactive magnetron sputtering.B doping, in combination with the highly energetic deposition conditions offered by HiPIMS, results in the suppression of the columnar grain mor-

“…The results can be explained via some parameters including phase structures, crystallographic orientation, grain size, dense, and so on. 8) In this case, the increase in the hardness of the samples can be ascribed to the formation of uniform fine particles or the changes of microstructure to the increased area fracture of grain boundaries, which may hinder dislocation movements. On the contrary, the decrease in the hardness for the samples deposited at the higher N 2 flow rate is attributed to the appearing of the dual-phase (fcc + hcp) structures and/or the increased grain size.…”

In this study, a Ti 50 Al 40 V 10 single alloying target is used to deposit TiAlVN coatings by a direct current (dc) magnetron sputtering technique. The structural, mechanical, and frictional properties of final coatings deposited at a various N 2 content are investigated. It reveals that TiAlVN coating transforms from a single-phase (cubic phase) to a dual-phase structure (cubic and hexagonal phases) with the increase of N 2 content. The highest hardness (³36.5 GPa) and elastic modulus (³372 GPa), and a good adhesion strength (³24.4 N) are achieved in the sample deposited with a N 2 flow rate of 6 sccm, which are determined by the nano-indentation and scratch test measurements. In addition, TiAlVN coating deposited with a N 2 flow rate of 3 sccm has the lowest friction coefficient in the dry and oily conditions.
