Influence of layer number on microstructure, mechanical properties and wear behavior of the TiN/Ti multilayer coatings fabricated by high-power magnetron sputtering deposition

Investigation of structural, mechanical, and corrosion properties of steel 316L reinforcement by hBN and TiC particles

“…Hence, strong bonding between reinforcing and matrix powders improves the wear resistance of the nanocomposite product. In the current study, TiC nanoparticles establish a strong bonding with steel 316L particles and increase forces against the plastic deformation and as a consequence, a lower wear rate is reported and resistance against the removal of the samples' surface occurs [33]. As well, hBN particles with a self-lubricating quality enhance the materials' wear properties, where the strong covalent and the weak Van der Waals bonding are between atoms and layers, respectively.…”

Functional Surface Coatings on Orthodontic Appliances: Reviews of Friction Reduction, Antibacterial Properties, and Corrosion Resistance

“…Among metal and metallic compound friction reduction coatings, tungsten disulfide (WS 2 ) was the first to be applied [ 22 ]. Since then, silver (Ag) coatings and metallic compound coatings, such as zinc oxide (ZnO) [ 23 , 24 , 25 , 26 , 27 ], titanium nitride (TiN) [ 28 , 29 , 30 , 31 , 32 , 33 ], and aluminum oxide (Al 2 O 3 ) [ 30 ], have also received good attention. Nonmetals, including carbon-based materials [ 34 ], polymers [ 35 , 36 , 37 , 38 , 39 ], and bioactive materials [ 40 ], are relatively new coating materials.…”

“…Nonmetals, including carbon-based materials [ 34 ], polymers [ 35 , 36 , 37 , 38 , 39 ], and bioactive materials [ 40 ], are relatively new coating materials. In addition, preparing nanoparticles and depositing them on orthodontic attachment surfaces via magnetron sputtering [ 30 , 33 ], evaporation [ 41 ], and immersion are also common techniques. These materials play an antifriction role mainly by filling the grooves on the surface of the appliances and forming a lubricating layer, which effectively reduces the dynamic and static friction between the archwire and the brackets [ 42 ].…”

“…The current trend tends to combine TiN with other application materials. TiN-derived coating materials such as titanium carbonitride (TiCN) [ 31 , 32 ], multilayer titanium nitride/titanium (TiN/Ti) [ 33 ], and nickel-titanium-molybdenum (Ni-Ti-Mo) composite coatings [ 57 ] not only have a more exact friction reduction effect than TiN, but are also more beneficial to clinical application due to other advantages.…”

A Comparative Investigation on Mechanical Properties of Tib₂/Cr Multilayer Film by Indentation

“…TiB2 has been wildly used for wear parts, seals, cutting tools, and metal matrix composites due to its high hardness and wear resistance [12]. Multilayering TiB2 with metallics (such as Cr [13], Ti [14], FeMn [15]), carbides and nitrides (such as TiAlN [16], TiN [17], TiC [18,19], VC [20], BN [21]), oxides (such as Al2O3 [22]), and carbon-based layers [23] have been reported to further improve the mechanical properties of the TiB2. In our recent work [24], alternating TiB2-dcMS and Cr-HiPIMS layers are used to fabricate TiB2/Cr multilayer films with varying the Cr interlayer thickness, 2 and 5 nm, and the substrate bias during growth of Cr interlayers from floating, to -60 V and -200 V. The results reveal that increasing the substrate bias during Cr interlayer growth from floating to -60 V produces increases of both film hardness and elastic modulus.…”
