This paper presents a comprehensive explanation of the formation of the electric arc between opening contacts in a current carrying electric circuit. As the contacts begin to open a molten metal bridge forms between them. The rupture of this bridge and the initial formation of the electric arc are studied in both atmospheric air and vacuum using experiments to determine the direction of metal t...

Plasma-based ion implantation (PBII) is usually carried out with isotropic gaseous plasmas, such as a discharge in nitrogen. More recently, it has been applied using drifting plasmas, such as those produced by cathodic arcs, in order to allow efficient implantation of metallic species. The condensable nature of a cathodic arc plasma allows for the deposition of ion-stitched thin film coatings, ...

CrTaN coatings have recently received increasing industrial interest due to their combination of high hardness, promising fracture toughness and excellent oxidation resistance. However, up now no thorough investigation on the thermal stability this coating system is available. Thus, within work, evolution microstructure phase composition an arc evaporated were illuminated in inert atmosphere 14...

OBJECTIVE The purpose of this study was to verify the antibacterial performance and cell proliferation activity of zirconium (Zr)-carbon (C)-nitride (N) coatings on commercially pure titanium (Ti) with different C contents. MATERIALS AND METHODS Reactive nitrogen gas (N(2)) with and without acetylene (C(2)H(2)) was activated by Zr plasma in a cathodic-arc evaporation system to deposit either ...

The extreme ultraviolet (EUV) reflectance of amorphous tetrahedrally coordinated carbon films (ta-C) prepared by filtered cathodic vacuum arc was measured in the 30-188-nm range at near normal incidence. The measured reflectance of films grown with average ion energies in the ~70-140-eV range was significantly larger than the reflectance of a C film grown with average ion energy of ~20 eV and o...

Metastable phases are often used to design materials with outstanding properties, which cannot be achieved with thermodynamically stable compounds. In many cases, the metastable phases are employed as precursors for controlled formation of nanocomposites. This contribution shows how the microstructure of crystalline metastable phases and the formation of nanocomposites can be concluded from X-r...

In this work the suitability of some Tibased coatings as coating for blood-contacting implants is analyzed. Layers of pure Ti, Ti nitride, Ti oxynitrides (TiN1-xOx with x = 0.25, 0.50, and 0.75) and Ti oxides were deposited from a plasma produced by cathodic arc evaporation under addition of N2 and/or O2. The oxynitrides are crystalline with the fcc structure of TiN up to x = 0.25. For x = 0.5 ...
