The utility of hard tribological coatings based on transition nitrides (e.g. CrN, TiAlN, CrAlN, etc.) as protective layers on various forming tools (e.g. die and its components used in high pressure die casting) has led to improvements in increased die life, reduced machine down time, and improved product quality. Moreover, recent advances in the coating design made it possible to obtain nanosc...

in the present study, the effects of growth defects and chromium content loss on the degradation of corrosion andpassivation of cathodic arc evaporation (cae-pvd) of stainless steel coating were investigated in 2 m sulphuricacid solution. eds analysis indicated that the micro-particles were obtained during the coating growth. in addition,it was detected that the growth defects had poor adhesion...

Carbon plasma nanocoatings with controlled fraction of sp(3)-C bonding were deposited on TiO2 nanorod arrays (TNAs) by DC magnetic-filtered cathodic vacuum arc deposition (FCVAD). The cytocompatibility of TNA/carbon nanocomposites was systematically investigated. Human umbilical vein endothelial cells (HUVECs) were cultured on the nanocomposites for 4, 24, and 72 h in vitro. It was found that p...

Filtered cathodic vacuum arc (FCVA) processed carbon films are being considered as a promising protective media overcoat material for future hard disk drives (HDDs). However, at ultrathin film levels, FCVA-deposited carbon films show a dramatic change in their structure in terms of loss of sp3 bonding, density, wear resistance etc., compared to their bulk counterpart. We report for the first ti...

Nitrogen doped tetrahedral amorphous carbon (ta-C:N) thin films were deposited on p-Si (1 11) substrates (1×10−3 to 6×10−3 cm) by a filtered cathodic vacuum arc technique with different nitrogen flow rates (3 and 20 sccm). The ta-C:N film coated samples were used as working electrodes to detect trace heavy metals such as zinc (Zn), lead (Pb), copper (Cu) and mercury (Hg) by using linear sweep a...

The electron field emission properties of tetrahedral amorphous carbon thin films deposited using a filtered cathodic vacuum arc system have improved as a result of surface treatment with H, O, and Ar ions. The limiting factor of the emission process does not appear to be only the front surface of the films. The improvement in the emission after ion beam treatment appears to be independent of t...

The influence of the metal content (0-28 at.%) on the structural, mechanical and tribological properties of a-C:Cu films grown by pulsed filtered cathodic arc deposition is investigated. Silicon and AISI 301 stainless steel have been used as substrate materials. The microstructure, composition and bonding structure have been determined by scanning electron microscopy; combined Rutherford backsc...

Hard, refractory thin films consisting of group IVB element mono-nitrides deposited using various chemical and physical vapour-deposition techniques are widely used in wear-resistant applications. As the demand for performance exceeds the capabilities of existing materials, new materials with superior properties must be developed. Here we report the realization and characterization of hard cubi...
