PURPOSE The aim of this in vitro study of titanium abutments was to investigate the extent of treatment traces, the roughness depth, and the quantity of titanium or, in the case of coated abutments, titanium nitride (TiN) removed from the surface after treatment with various instruments. MATERIALS AND METHODS Eleven uncoated, mechanically smoothed abutments and 11 TiN-coated abutments were us...

The use of ionized gaseous medium (IGM) to prepare a hard alloy material surface by grinding and its effect on the coating quality was investigated. During grinding, IGM was fed to the cutting area by different methods namely: clockwise (longitudinal), anticlockwise (opposed) and transverse (Cross) feeding, respectively. Thereafter, the samples were coated with a titanium nitride on a modern va...

The increasing use of titanium and its alloys in the manufacture implants results from simultaneous presence excellent biocompatibility, relatively low density, high mechanical properties, corrosion resistance. Unlike application characteristics, is classified as a difficult-to-machine material. Therefore, one constant challenge for implant manufacturers to correctly choose turning tools each a...

A novel noble metal-free catalyst, with nitrogen-doped amorphous carbon and titanium nitride particles supported on SiC (NC-TiN/SiC), was synthesized. The NC-TiN/SiC catalyst exhibited excellent oxygen reduction reaction activities as well as superior stability and methanol tolerance. The catalytic activities were attributed to the synergistic effect of TiN and NC.

The multilayer antimony-doped tin dioxide coating was obtained by cathodic deposition of multilayer metal-hydroxide coating with near 100-nm thickness layers on the alloy underlayer accompanied by the anodic oxidation of this coating. The potential regions of deposition of tin, antimony, tin-antimony alloy, and mixture of this metals and their hydroxides in the pyrophosphate-tartrate electrolyt...

A dry bracelet electrode for electrocardiographic (ECG) signal monitoring was developed and successfully tested in human volunteers. The new electrode dispenses with the usual gel application and the previous skin preparation to monitor the signal. It was fabricated from a polyethylene tereftalate (PET) polymer sheet that was coated with a thin conductive titanium nitride (TiN) layer. As the di...

In this paper, we describe our all-titanium microelectrode array (tMEA) fabrication process and show that uncoated titanium microelectrodes are fully applicable to measuring field potentials (FPs) from neurons and cardiomyocytes. Many novel research questions require custom designed microelectrode configurations different from the few commercially available ones. As several different configurat...

This study investigated the mechanical properties and residual stress of high-power impulse magnetron sputtering (HiPIMS) titanium nitride (TiN) thin film capping on cold spray (Ti) coating. TiN/Ti duplex coating was deposited Ti substrate, prepared in three cases with different numbers layers. The determined Young’s modulus, hardness, roughness TiN coatings by nano-indentation AFM. measurement...

The aim of this study was to assess the impact of titanium nitride coatings on CoCr alloy metal parts in framework dentures on human palatal epithelium cytology compared to framework dentures made with the same alloy but without titanium nitride coating, and to acrylic dentures. Every prosthetic restoration introduced into the oral cavity and remaining in direct contact with the palate exhibits...
