“…When Al and C are simultaneously added to the TiN system, quaternary coatings show a unique combination of both high thermal stability and outstanding tribological properties [23,24]. The studies described in [23][24][25][26][27][28][29] show that the content of C plays an important role in the determination of the structure and properties of (Ti,Al)CN coatings, since C can exist in various forms. Another important factor is the content of N. The unsaturated and supersaturated contents of N result in the formation of different nitride phases and coating properties [23].…”

The study investigated the performance properties of a carbide tool with multilayer composite nano-structured Ti-TiCN-TiAlCN and Ti-TiCN-TiAlCrCN coatings, obtained by filtered cathodic vacuum-arc deposition (FCVAD). The study considered the structure of these coatings and their basic mechanical properties (hardness, strength of adhesion bond to substrate, and elemental composition). The study included cutting tests of carbide tools with those coatings in comparison with uncoated tools and tools with reference Ti-TiN coating. The tests were carried out during the turning of steel C45 at various cutting speeds (300, 350, and 400 m/min). The study included research of the kinematics of tool wear and the nature of cracking in the structure of coatings. Diffusion processes in the system of tool substrate-coating material during machining were also studied. Highlights-Study of the properties and structure of Ti-TiCN-TiAlCN and Ti-TiCN-TiAlCrCN.-Cutting tests of tools with the coatings under study at different cutting speeds.-Mechanisms of wear and cracking in coatings.-Diffusion processes in coated tools during cutting of metal.

“…The mechanical behaviour of the coatings was characterized by the ratios H/E r and H/E r 2 and the elastic recovery ER (%) [19]. The H/E r ratio indicates the amount of strain a coating can stand before a permanent deformation happens, so a higher H/E r ratio indicates a better wear resistance [74 78].…”

“…In all of the examples presented above, the C or N contents within the coatings were tuned in order to get improved characteristics targeted at specific applications. Carbonitride coatings, MeCN, where Me can be either Ni, Cr, Fe, Al, Hf, Ti, Zr, Si, or a combination of these have been used for dies and cutting tools due to their good resistance to oxidation and to thermal cycling [7,19], wear resistant [25 28] , microelectronics [29] , responsive sensors [30], hot work tool steels [31], diffusion barrier coatings [25,26,32], coatings with high toughness [4], anticorrosive coatings [33 36]. Due to their high hardness and low friction coefficient, TiCN coatings deposited on a broad range of substrates are widely used in many industries, aiming for a variety of applications accepting low service temperatures (e.g.…”

In this work, the influence of NbZr and ZrSi addition to TiCN coatings are studied, aiming for their use as protective layers for parts subjected to severe corrosion and wear. The coatings with C/N ratios ranging from 0.4 to 2.5 were deposited using the cathodic arc technique in a mixture of N 2 and CH 4 gases, on 316 stainless steel discs and Si (111) wafers. All the coatings exhibited residual compressive stresses, with values ranging from approximately-2.4 GPa to-3.5 GPa. The addition of Si led to an increase in hardness, regardless of the C/N ratio. All coatings with high C/N ratio (~2.5) presented slightly lower stress values and superior performance in 3.5% NaCl corrosive solutions, the best performance being obtained for the TiSiZrCN coating, which exhibited the highest protective efficiency to corrosion (97.8 %), due to its low corrosion current density (1.734 µA/cm 2) and high polarization resistance (31.775 k). The tribological tests, performed at 23 °C and 250 °C, indicated that abrasion and oxidation were the predominant wear mechanism for all

“…In the last decade, numerous papers have been devoted to the MeSiC, MeSiN, and MeSiCN hard coatings, where Me is a transition metal and Si is an alloying element. These coatings were found to have superior mechanical properties (high hardness and strength), thermal stability, reduced friction, and enhanced wear-corrosion resistance [69,70]. In particular, investigations on TiSi-based carbide or carbonitride coatings as a possible candidate for a variety of metallic implants have attached interest because they can combine the mechanical, anticorrosive, and tribological properties of the TiC or TiCN with the biological characteristics of the SiC or SiCN [71,72].…”
