Titanium nitride thin films were grown on 304 stainless steel substrates at various nitrogen/argon flow ratios by ion beam sputtering (IBS) technique. The current research is a follow up study on the influence of gas ratio on structural and corrosion properties in the TiN coated 304 stainless steel. Film structural identification of phases was performed using X-ray diffractometry (XRD). Sca...

Nanocomposite coatings composed of two phases with atomically sharp phase boundaries, show interesting mechanical properties. These properties are often originating from their high interface to volume ratio. Composites of nanocrystalline titanium nitride (TiN) grains surrounded by a one to two monolayer thick interlayer of silicon nitride (Si3N4) show an enhanced nanohardness. The central theme...

Abstract Plasmonic nanostructures offer wide range of diagnostic and therapeutic functionalities for biomedical applications. Gold nanoparticles (Au NPs) present one the most explored nanomaterial in this field, while titanium nitride (TiN is a new promising with superior plasmonic properties biomedicine. However conventional chemical techniques synthesis these nanomaterials cannot always match...

Ultrasonic force microscopy has been applied to the characterization of titanium nitride coatings deposited by physical vapor deposition dc magnetron sputtering on stainless steel substrates. The titanium nitride layers exhibit a rich variety of elastic contrast in the ultrasonic force microscopy images. Nanoscale inhomogeneities in stiffness on the titanium nitride films have been attributed t...

STATEMENT OF PROBLEM Screw loosening has been a common complication and still reported frequently. PURPOSE The purpose of this study was to evaluate abrasion of the implant fixture and TiN coated abutment screw after repeated delivery and removal with universal measuring microscope. MATERIAL AND METHODS Implant systems used for this study were Osstem and 3i. Seven pairs of implant fixtures,...

Titanium nitride (TiN) thin films deposited by high-power pulsed magnetron sputtering usually have a high compressive residual stress, which is not conducive for the adherence of TiN films. This study investigated potential Ti2AlN releasing stress HPPMS-deposited and evaluated strength hardness TiN/Ti2AlN multilayers introducing MAX phase to form multilayers. The results showed that smooth with...

Optical responses of titanium nitride and zirconium nitride are studied in the visible and near-infrared regions for localized surface plasmon applications. Both materials are found to be promising alternatives to noble metals. OCIS codes: (250.5403) Plasmonics; (160.4236) Nanomaterials Localized surface plasmon resonances (LSPR) have been studied intensely for the last few decades. Other than ...

Unprecedented multi-channel TiN micro/nanotubes as well as various metal nitride nanofibers, including TiN, VN, NbN and ternary metal nitride nanofibers, were fabricated by a template free electrospinning method combined with post-nitridation.

The purpose of this paper is to utilize the signaling pathway polymerase chain reaction (PCR) arrays to investigate the activation of two important biological signaling pathways in endothelial cell adhesion and growth mediated by adsorbed serum protein on the surface of bare and titanium nitride (TiN)-coated nickel titanium (NiTi) alloys. First, the endothelial cells were cultured on the bare a...

The manufacture of medical and aerospace components made of titanium alloys and other difficult-to-cut materials requires the parallel development of high performance cutting tools coated with materials capable of enhanced tribological and resistance properties. In this matter, a thin nanocomposite film made out of AlCrN (aluminum-chromium-nitride) was studied in this research, showing experime...
