Synthesis and characterization of TiN, TiAIN and TiN/TiAIN biocompatible coatings

Attenuation of the in vitro neurotoxicity of 316L SS by graphene oxide surface coating

“…Various approaches to coat bare implant surfaces with biocompatible materials like diamond-like carbon (5), SiC (6), TiN (7), TiO 2 (8), polymers (9) and biological moieties such as heparin (10) and dopamine (11) have been adopted for a variety of applications. But, each of these coating materials have inherent limitations of instability.…”

Tribocorrosion behavior and ions release of CoCrMo alloy coated with a TiAlVCN/CN multilayer in simulated body fluid plus bovine serum albumin

“…Since the long-term durability of the prosthetic joint materials rely on the successful control of both the corrosion that produces ions release and the tribocorrosion resistance that produces ions release and oxide or plastic debris, Physical Vapor Deposition (PVD) multilayer coatings offer a multifunctional protection alternative and good adherence to metallic substrates in comparison to the monolayer coating [15,[21][22][23][24][25][26]. The multilayer combine the properties of different materials in a single protective layer.…”

“…For example crystalline transition metal nitride/a-CNx multilayer such as TiN/CNx, ZrN/CNx, CrN/CNx and NbN/CNx exhibit good tribological behavior and improved adhesion on the metal substrates by means of stress relaxation [29]. The corrosion resistance of CoCrMo coated with TiN/TiAlN multilayers is better than the CoCrMo alloy coated with TiN or TiAlN single coatings [23]. In a previous work we reported that a similar multilayer of TiAlCN/CNx multilayer improved the mechanical properties and the corrosion resistance of CoCrMo [30].…”

A comparative study of the corrosion performance of titanium (Ti), titanium nitride (TiN), titanium dioxide (TiO2) and nitrogen-doped titanium oxides (N–TiO2), as coatings for biomedical applications

“…These issues must be addressed because preventing early failure of implants caused by corrosion is crucial. Recent methods with considerable potential include the deposition of a protective ceramic coating (e.g., TiN, DLC, TiAlN, TiN/TiAlN, TaN, and ZrN coatings) on the metal surface [5][6][7][8][9][10][11][12][13][14].…”
