Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Investigating the effect of nitrogen on the structural and tribo-mechanical behavior of vanadium nitride thin films deposited using R.F. magnetron sputtering

“…7a, b, 8a, b). Thus, this may have significantly contributed to a noticeable increase in the friction coefficient value between the surfaces of the VN film and the 100Cr6 ball [52].…”

Effect of annealing treatment on the microstructure, mechanical and tribological properties of chromium carbonitride coatings

“…By using a three-sided pyramidal diamond tip (Berkovich indenter), a maximum depth of 200 nm was considered, leading to a maximum load of approximately 10 mN. The loading and unloading of the indentations were carried out under loading control with a nominal rate of 0.05 mN/ s. Indentation curves were described by means of the general methodology for the films around 2 μm thick [16].…”

“…The morphology and composition of damaged samples were evaluated with an SEM equipped with an EDS. The wear volume and the surface roughness were determined with an optical profilometer (VEECO, Wyko-NT 1100) [16].…”

“…If we consider the formation energy of these compounds, the Cr 2 N can be formed in the interval of 7-10 at.% N 2 at 650°C and requires formation energy of about 397.4 ± 0.4 eV [12,16,18]. This value is higher than that of CrN phase which is formed at higher nitrogen concentration (> 15% N 2 in the gas mixture) at 750°C and needs formation energy of about 396.8 ± 0.4 eV [16]. Thus, on one hand, the formation of different phases of chromium nitrides can be justified and attributed to the nitrogen percentage.…”

Synthesis, microstructural characterization and nanoindentation of Zr, Zr-nitride and Zr-carbonitride coatings deposited using magnetron sputtering

“…Over the years, various properties of Zr-nitride coatings have been investigated for a range of applications. It has been evaluated for its microhardness, adhesion and wear resistance in tribological applications and as a barrier material in integrated circuits [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , erosion protection for turbine and compressor blades [23] , [24] , [25] , biocompatibility [26] , optical and electrical properties [27] , [28] , nuclear fuel element compatibility [29] , [30] , [31] , and orientation dependence, microstructure, composition and corrosion [32] , [33] , [34] , [35] , [36] , [37] , [38] , [39] , [40] . Influence of synthesis parameters on coating properties have also been investigated [41] , [42] , [43] , [44] , [45] , [46] .…”
