“…In the XRD pattern of the as-deposited coating, peaks (111) and (002) corresponding to cubic (Ti,Al)N were identified ( Figure 7 a). The peaks were also found in previous studies [ 21 , 30 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ], sometimes with slightly shifted 2θ values. This shift is caused by substitution of Ti by Al, and possibly Si, and also due to the effects of crystallite size and internal stresses [ 30 ].…”

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 reason for this may be the fragile layer formed in the thermal treatment process as well as the evident softening of the substrate. This phenomenon could be explained by the phase transformation of fcc-AlN into hcp-AlN after 800 °C thermal treatment [ 51 ].…”

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.

“…Hard coatings with transition element nitrides, such as TiN, AlN and TaN, are widely applied on the surfaces of molds and cutting tools because their outstanding performance such as higher hardness and excellent wear resistance [1][2][3]. Li and Veprek doped Si into TiN to form multiphase TiSiN nanocomposite coatings consisting of nanocrystalline TiN and amorphous Si 3 N 4 [4][5].…”

The purpose of this study was to optimize V content of TiSiN/TaVN nanomultilayers. TiSiN/TaVN nanomultilayers with various V contents were deposited on 304 stainless steels and Si wafers. The structures and properties of TiSiN/TaVN nanomultilayers were analyzed and characterized. The results show that TiSiN/TaVN nanomultilayers exhibit the face-centered cubic (FCC) structure and preferred orientation on the (111) and (200) planes. With the increasing of V contents, the diffraction peaks of TiSiN/TaVN nanomultilayers were shifted to larger angles. Paralleling to the growth direction of TiSiN/TaVN nanomultilayers, an alternating stress fields are generated to enhance their strength. The hardness and elastic modulus of the nanomultilayers firstly increases and then decreases and friction coefficient firstly decreases and then increases with increasing of V contents. TiSiN/TaVN nanomultilayer with 15 at.% V content indicates the maximum hardness of 27.23GPa, the maximum elastic modulus of 280.96GPa and the highest resistance against plastic deformation. TiSiN/TaVN nanomultilayer with 15 at.% V content has minimum friction coefficient of 0.16 because Magnéli phase oxide V2O5 is formed during the reciprocating sliding friction process and H3/E2 of TiSiN/TaVN nanomultilayer with 15at.% V content is highest.
