“…The TaNdominant Ta54N46, Ta40W15N45 and Ta36W24N40 films exhibited distinct morphologies after the wear test. The Ta54N46/Ta/SUS420 sample exhibited adhesive wear because of the chemical reaction on the contact area between the counterpart ball and films [59,66]. The wear debris attached to the films.…”

In this study, TaWN films were fabricated through co-sputtering. The effects of W addition on the structural variation and mechanical properties of these films were investigated. TaWN films formed face-centered cubic (fcc) solid solutions. With the increase in the W content, the fcc phase varied from TaN-dominant to W2N-dominant, which was accompanied by a decrease in the lattice constant and alterations in material characteristics, such as the chemical bonding and mechanical properties. The phase change was further correlated with the bonding characteristics of films examined by X-ray photoelectron spectroscopy. The hardness increased from 21.7 GPa for a Ta54N46 film to 23.2–31.9 GPa for TaWN films, whereas the Young’s modulus increased from 277 GPa for the Ta54N46 film to 302–391 GPa for the TaWN films. The enhancement in films’ mechanical properties was attributed to the strengthening of the solid solution and the phase change. The wear behavior of the fabricated TaWN films was evaluated using the pin-on-disk test. The Ta17W55N28 and Ta36W24N40 films exhibited an abrasive wear behavior and low wear rates of 4.9–7.6 × 10−6 mm3/Nm.

Silicon (Si) has been the paradigm of the electronic industry, because it has been used in fabrication of different electronic circuit elements such as diodes, operational amplifiers, transistors, and in the last few decades, it has been the base material of the development of solar energy industry. However, other research fields in which the physical and chemical properties of Si have demonstrated to be relevant to applications in areas such as the mechanical, optical, electrical, and electrochemical are less known. Therefore, it is relevant to know the technology that has generated materials with new or better physical and chemical properties, such as the nanocomposite materials that have been growing in thin films. These films exhibiting new properties with respect to the bulk material and with the addition of Si, have demonstrated to improve the properties of the transition metal nitride (MeN), obtaining thin films with a high nanohardness, wear resistance, corrosion resistance, and high thermal stability. Therefore, the main objective of this chapter is to know the role that plays the incorporation Si in growth, microstructure, chemical composition, and functional properties of ZrN thin films.

“…In our previous study, CrAlN monolithic layer coatings showed great mechanical properties such as high hardness (35 GPa) and high adhesion (46 N for SKD61 steel), but the coatings also showed relatively poor wear resistance and thermal stability [4]. In addition, other monolithic layers such as CrZrN and CrZrSiN coatings with a low friction coefficient of approximately 0.25 and excellent thermal stability up to 800 • C have been reported [13][14][15][16][17]. To deposit a CrAlN coating on a very hard WC (≈20 GPa) substrate without delamination, the use of an interlayer of these Cr-based nitride compounds could be advantageous for adhesive strength by reducing the gap of hardness and Young's modulus between the CrAlN coating and the WC substrate.…”

CrAlN coatings have earned significant attention for use in cutting tool coating applications due to their excellent properties such as high hardness and superb oxidation resistance. It is well known that the interlayer between the coating and the substrate can influence the mechanical properties of the coatings. In this work, three interlayers—CrN, CrZrN, and CrN/CrZrSiN—were synthesized between a CrAlN coating and a tungsten carbide substrate to improve the mechanical properties and thermal stability of the CrAlN coating. All the CrAlN coatings with their respective interlayers showed high hardness values in the range of 34.5 to 35.1 GPa, and they were not significantly affected by the interlayer type. However, wear and scratch tests showed that the CrAlN coatings with CrN and CrN/CrZrSiN interlayers exhibited an improved friction coefficient of 0.33 and adhesion strength (Lc2) of 69 N compared to the CrAlN coating with the CrZrN interlayer. These improved wear properties were attributed to the H/E ratio of the interlayer between the coating and the substrate, in that the CrN and CrZrSiN interlayers effectively induced a smooth transition of the coating stress under a loading condition. During the thermal stability tests, the hardness of the CrAlN coating with the CrN/CrZrSiN interlayer was maintained up to 1000 °C due to the excellent oxidation resistance of the CrZrSiN layer, which contained an amorphous SixNy phase.
