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...

TiN films were prepared by the Cathodic arc evaporation deposition method under different negative substrate bias. AFM image analyses show that the growth mode of biased coatings changes from 3D island to lateral when the negative bias potential is increased. Nanohardness of the thin films was measured by nanoindentation, and residual stress was determined using Grazing incidence X ray diffract...

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...

(Ti, Al)N/MoN and CrN/MoN multilayered films were synthesized on Si (100) surface by multi-cathodic arc ion plating system with various bilayer periods. The elemental composition and depth profiling of the films were investigated by Rutherford backscattering spectroscopy (RBS) using 2.42 and 1.52 MeV Li2+ ion beams and different incident angles (0°, 15°, 37°, and 53°). The microstructures of (T...

Nitrogen doped tetrahedral amorphous carbon (ta-C:N) thin films were grown on p-Si(1 1 1) substrates using filtered cathodic vacuum arc (FCVA) deposition by varying nitrogen flow rate. The effect of nitrogen flow rate on the corrosion performance of the films was investigated through potentiodynamic polarization and immersion tests in 0.6 M NaCl solutions. The polarization results showed that t...
