Synthesis and characterization of the complex nanostructured thin films based on titanium by
Thermionic Vacuum Arc (TVA) method
Rodica VLADOIU
Ovidius University of Constanta, Romania
Nowadays, a great interest is paid on the development of plasma technology applications with particular emphasis on
the fabrication of nanostructured thin film, combined with the study of applications of plasmas in nanotechnology. For
this reason, plasma/surface interactions and growth mechanisms have to be taken into account for the definition, evaluation
and comparison of the different types of coating equipment and achievable coating results. Titanium based nanocomposites
owing to their remarcable properties of the coating surfaces such as wear resistance, roughness, low friction coefficients have
been synthetized and investigated in different combination and forms, such as multi-component composites. The aim of this
work is to find the best combination for coating the mechanical parts of components by suitable complex nanocomposites
and by using innovative technology For instance, titanium nanocomposites are characterized by very high tensile strength
even at high temperatures, light weight, high corrosion resistance, and as strong as steel, but 45% lighter. Binary, ternary thin
films as well as single thin films were deposited using Thermionic Vacuum Arc (TVA) technology. The thermionic vacuum
arc (TVA) is an original deposition method using a combination of anodic arc and powerful electron gun system (up to 600
W) for the growth of thin films from solid precursors under a vacuum of 10−6 Torr. For certain operating conditions the
plasma source produce energetic ions without any additional ion acceleration means like acceleration grids or polarization
systems. Results on the surface morphology and wettability of the obtained multifunctional thin films were reported by using:
Transmission Electron Microscopy (TEM Phillips CM 120 ST, 100 kV), Scanning Electron Microscopy (SEM, Zeiss EVO 50
SEM) and Free Surface Energy (FSE) by See System. Nanostructured coatings with homogenous and dense surface without
any faults (pinholes and cracks) were achieved at low temperatures to not affect the materials properties. Nanocomposite
coatings of Ti based consisting of crystalline phase embedded into an amorphous matrix constitute a multifunctional coating
architecture due to its combination of properties, suitable for emerging applications in metallurgical industry, yielding an
enhanced corrosion resistance.
