Nanostructured ceramic coatings are being intensively investigated because they open a wide field of new materials with improved mechanical and tribological properties. The final behaviour of such coatings depends on their composition and microstructure. Si addition in nitride compounds has shown to improve significantly their hardness. For instance, in the TiSi-N coating system, coating hardne...

In this study, Ti, Al and N doped DLC – referred to here after as “(Ti,Al)CN/DLC composite”- coating and pure diamond-like coating (DLC) were produced by cathodic arc deposition technique and the effects of the coating thickness on their tribological properties were evaluated. The coatings were characterized, using scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffrac...

The article includes research results for the functional properties achieved a wide range of sintered tool materials, including carbides, cermets and three types Al2O3 oxide ceramics ((Al2O3 + ZrO2, TiC SiC(w)) with (Ti,Al)N coating deposited in cathodic arc evaporation (CAE-PVD) method comparison uncoated materials. For all coated samples, uniform wear pattern on shank was observed during meta...

The electron-spin-resonance (ESR) features of tetrahedral amorphous carbon (ta-C) samples deposited by S-bend filtered cathodic vacuum arc (FCVA) are investigated in a wide temperature range (4.3–295 K) before and after postdeposition annealing at 500 C. Special attention is given to the temperature dependence of the linewidths. While the sp content does not change with annealing, the temperatu...

Nitrogenated diamond-like carbon (N:DLC) thin films fabricated with filtered cathodic vacuum arc (FCVA) can have a high sp content. Their superior electrochemical properties such as wide potential window and low background current make them a more promising electrode material than conventional carbon-based electrodes. The N:DLC films give pronounced signals for tracing analysis of Pb, Cu and Hg...

Nitrogen doped diamond-like carbon (N-DLC) thin films were prepared on n-Si substrates using a filtered cathodic vacuum arc deposition method. Square wave anodic stripping voltammetry (SWASV) was used to trace Pb and Cu in a neutral KCl solution with pH 7. Stripping voltammograms of Pb and Cu were analyzed in terms of metal concentration, deposition time and deposition potential. The SWASV resu...
