“…At 800 °C, hardness decreased. This may be attributed to the densification of the microstructure at moderate temperatures and the phase transformation at high temperatures where the cubic nitride phase transforms into a hexagonal nitrides phase [ 21 , 46 ].…”

“…Physical vapor deposition (PVD) for tool steel applied in various areas is a promising and effective technique to improve the mechanical performance and serving lives [ 14 , 15 , 16 , 17 ]. These quaternary coatings consist of a metastable amorphous phase which is crystalized after thermal treatment into an fcc/wurtzite lattice with high atomic density, forming a coating with a columnar structure and high hardness [ 18 , 19 , 20 , 21 , 22 ]. During operation, it is expected that these materials will suffer repetitive heating and cooling cycles with high temperatures reached in the coating of tool materials [ 23 , 24 ].…”

“…It is worth mentioning that those coating/substrate systems will undergo thermal cycles during operation, and it is relevant to understand the evolution of the mechanical properties under such cycles. In this sense, Liu et al [ 28 ] observed the evolution of hardness after the thermal treatment of AlCrSiN and AlTiSiN coatings on stainless steel, reporting a decrease in the values after thermal treatment of 600 °C [ 21 , 33 , 34 ]. However, they did not report any adhesion testing.…”

The objective of this study was to explore the mechanical properties of AlCrSiN and AlTiSiN coatings deposited on Inconel and steel substrates after thermal treatments of 500 °C and 800 °C. Nanoindentation was used to measure the hardness and elastic modulus of the coatings, and microindentation was used for observing the contact damage with Hertzian contact loadings. Microscratch and Mercedes tests were used to evaluate the adhesive strength between coating and substrate with both progressive and static loads, respectively. The surface damage was inspected by optical microscopy and scanning electron microscopy (SEM). Focus ion beams (FIB) were used to mill the cross-sections in order to detect the extent and mode of failure. The results show that AlCrSiN coatings and Inconel substrates exhibit better mechanical performance, even after thermal treatments.

“…The properties of TiN can be enhanced by Al addition [ 6 ]. The presence of Al in the TiAlN coating results in an improvement of mechanical properties [ 7 , 8 , 9 , 10 ] and increased oxidation resistance [ 11 , 12 , 13 ]. As such, the TiAlN coatings are some of the most widely used PVD coatings for cutting tools.…”

The present work investigates the influence of isothermal annealing on the microstructure and oxidation behavior of nanocomposite coatings. AlTiSiN/TiSiN coatings with TiSiN adhesive layer were deposited onto a high-speed steel substrate via physical vapor deposition. The coatings were investigated in the as-deposited state as well as after annealing in air at 700, 800, 900 and 1000 °C, respectively. The microstructure and morphology of the coatings were observed using scanning electron microscopy and transmission electron microscopy. The chemical composition and presence of oxidation products were studied by energy-dispersive X-ray spectroscopy. The phase identification was performed by means of X-ray diffraction. In the microstructure of the as-deposited coating, the (Ti1-xAlx)N particles were embedded in an amorphous Si3N4 matrix. TiO2 and SiO2 were found at all annealing temperatures, and Al2O3 was additionally identified at 1000 °C. It was found that, with increasing annealing temperature, the thickness of the oxide layer increased, and its morphology and chemical composition changed. At 700 and 800 °C, a Ti-Si-rich surface oxide layer was formed. At 900 and 1000 °C, an oxidized part of the coating was observed in addition to the surface oxide layer. Compared to the as-deposited sample, the oxidized samples exhibited considerably worse mechanical properties.

“…The most used tool coatings are transition metal carbides/nitrides with high hardness and excellent thermal stability, such as TiN, CrN, TiAlN, AlCrN, TiAlSiN, etc. They can increase tool wear resistance by several times (Ravi et al, 2017;Liu et al, 2018;Su et al, 2017). However, those hard coatings sometimes increase workpiece material adhesion on tool surface (Li, S. et al, 2018), leading to chip removal difficulties in dry drilling process.…”
