“…The high−resolution transmission electron microscopy (HRTEM) images also show that the nanomultilayer structure consists of TiSiN film (dark zone) and CrAlN film (bright zone). Part of the amorphous zone was detected in the TiSiN film, which may be related to the existence of SiN x [ 15 , 26 ]. The indexed selected−area electron diffraction (SAED) image in Figure 5 e presents polycrystalline diffraction rings with randomly distributed spots, indicating that this coating is composed of fcc single−phase solid solution [ 27 ].…”

Impact Abrasive Wear Property of CrAlN/TiSiN Multilayer Coating at Elevated Temperatures

et al. 2022

The impact wear property of hard coatings at elevated temperatures is of particular interest for applications in nuclear power plants. This study evaluated the impact wear behavior of two CrAlN/TiSiN coatings with and without sand. Alternately grown CrAlN and TiSiN films with modulation periods of 455 and 19 nm were formed in a columnar structure. The nanomultilayer shows better impact wear resistance than multilayer films with and without sand. The energy absorption rate has a similar trend to wear rate, leading to lower rebound velocity and peak impact force of the nanomultilayer compared with that of the multilayer. CrAlN/TiSiN coatings can protect the 308L substrate from oxidation. The dominant impact wear mechanism without sand is plastic deformation, and this wear region can be defined as the percussive zone. Peeling occurs on the multilayer surface without sand after 104 percussions, leading to rapid oxidation of the 308L substrate at 500 °C. Due to the abrasion effect, the wear rate of the sample with sand increases by an order of magnitude compared to the sample without sand. The wear scar of the sample with sand can be divided into the mixing zone and the sand−affected zone from inside to outside. Fe oxides are formed beyond the unbroken coating, which may be related to the outward diffusion of Fe.

“…The crystal TiN phase is surrounded by Si 3 N 4 , resulting in refinement of grains and enhancement of hardness. However, a monolayer coating has high residual stress and poor toughness, which limit its application as a protective coating [ 15 ].…”

“…In the machining process, a tool must withstand mechanical and thermal stresses, which can be mitigated by depositing a hard coating layer or multilayer onto its surface. The coating improves the tools utility properties, such as hardness, wear resistance, thermal stability, oxidation resistance and coefficient of friction, thereby improving the quality of the machining process and prolonging the service lifetime [ 1 , 2 ]. The first commercially used physical vapor deposition (PVD) coating for cutting tools was titanium nitride (TiN) [ 3 ].…”

Influence of Isothermal Annealing on Microstructure, Morphology and Oxidation Behavior of AlTiSiN/TiSiN Nanocomposite Coatings

et al. 2023

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.

“…Thus, it has been successfully used to enhance the physical and mechanical properties of engineering components [7]. The excellent properties of TiSiN coatings are attributed to the nanocomposite structure that consists of nanocrystalline TiN grains embedded in amorphous silicon nitride (Si 3 N 4 ) matrix [8][9][10]. The mechanical and tribological properties of the TiSiN strongly depend on microstructure and Si content [11,12].…”

“…%, respectively. The Si 3 N 4 phase has not been detected by XRD due to its amorphous character[7,8,10,18,20]. It could be concluded that the WN x /TiSiN multilayer revealed the same crystal structure presented in the monolithic coatings, namely body-centered cubic W (ICSD 98-065-3433) and face-centered cubic TiN (ICSD 98-064-4770) phases.…”

The present work deals with the comparison of selected properties of WNx/TiSiN multilayer and respective WNx and TiSiN monolithic coatings that were deposited at the same parameters. The effect of the multilayer architecture on the structure and mechanical properties of WNx/TiSiN multilayer was studied in detail. The multilayers and monolayers were fabricated on high-speed steel substrates by unbalanced direct magnetron sputtering from W (purity 99.95 %) and Ti80Si20 (purity 99.50 %) targets. The chemical composition and the cross-sectional morphology of multilayer and single-layer coatings were characterized by scanning electron microscopy (SEM) equipped with wave-dispersive X-ray spectroscopy (WDS). The structure was analyzed by X-ray diffraction (XRD). The hardness and Young’s modulus of multilayer and coatings were investigated using the nanoindentation method. Results showed that the WNx/TiSiN multilayer, possessing cubic W and TiN phases and a dense layered microstructure, showed slightly improved hardness (28.5 ± 3.5 GPa) and HIT/EIT parameter (0.087), as compared with the WNx and TiSiN coatings. It has been shown that the design of multilayered structure of WNx/TiSiN coating is a promising way to tailor the microstructure and properties of the hard coatings.
