Structure and properties of magnetron-sputteredTiVN coatings

Oxidation Behavior and Mechanisms of TiAlN/VN Coatings

“…The VN, which also has the B1 NaCl structure, exhibits continuous solid solubility with a number of metal nitrides and carbides, such as TiN, TiC, TiAlN, VC, and NbN. [9] Knotek et al [10] found that the addition of V to TiN and Ti-Al-N enhanced wear performance, with the best wear resistance obtained in a Ti-V-N coating with 29 at. pct V. TiAlN/VN multilayers, which incorporate VN into TiAlN as a nanoscale multilayer (also referred to as a ''superlattice'') coating, have exhibited excellent sliding wear resistance (1.26 · 10 -17 m 3 AEN -1 m -1 ) with a lower friction coefficient at room temperature (l = 0.4, pin-on-disc test, Al 2 O 3 ball counterpart) in comparison to other wearresistant coatings, [8] e.g., TiAlN/CrN(sliding wear coefficient 2.4 · 10 -16 m 3 AEN -1 m -1 , l = 0.7 to 0.9).…”

Effect of codeposition parameters on the hardness and adhesion of TiVN coatings

“…The ternary TiVN system is formed due to the total miscibility of the Ti-V system [5], which creates a solid solution while preserving the crystalline structure B1 of TiN. Such miscibility can be attributed to the small difference between the atomic radii of Ti (1.36 Å) and V (1.25 Å) [6]. The vanadium content of the TiVN coatings influences the hardness of the coating [7] and reduces its friction coefficient [8,2].…”

Characterisation of ternary TixV1−xNy nitride prepared by mechanosynthesis

“…The traditional synthetic methods for generating these types of compounds include the amonolysis of ternary oxides [8,9] and metal alloys [10][11][12]; solid state reactions using chlorides, nitrates, and pre-structured oxides [13][14][15][16][17][18][19]; and deposition methods [20][21][22][23][24][25]. Information in the literature concerning titanium-vanadium nitride has shown the superior performance of such coated ternary compounds to those of both pure TiN and VN, with respect to their hardnesses and tribological environments [26][27][28][29][30][31][32][33][34][35][36][37][38]. A small addition of vanadium to titanium nitride improved the supercapacitor properties of TiN [39].…”

“…A small addition of vanadium to titanium nitride improved the supercapacitor properties of TiN [39]. Traditionally, titanium and vanadium nitrides have been synthesised as thin films using different deposition methods, such as cathodic arc deposition [31], cathodic magnetron sputtering [32], reactive magnetron sputtering [33][34][35], or chemical vapour deposition, [36][37][38]40,41] or by the direct nitridation of metal alloys [42][43][44][45]. To our knowledge, only two works have reported the preparation of Ti x V 1-x N y in bulk.…”
