Findings from Research Institute Yields New Findings on Vacuum Technology (Deposition and characterization of Ti-C-x-N-y nanocomposite films by pulsed bias arc ion plating)

By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Vacuum Technology are presented in a new report. According to news reporting originating from Beijing, People's Republic of China, by VerticalNews correspondents, research stated, "A series of Ti-C-x-N-y films with different compositions were deposited by pulsed bias arc ion plating. In order to investigate their dependences on compositions, the surface morphology, composition, microstructure, and mechanical properties were assessed by means of scanning electron microscope, X-ray photoelectron spectroscopy, Raman spectroscopy, grazing incident X-ray diffraction, high resolution transmission electron microscopy, and nano-indentation."

Our news editors obtained a quote from the research from Research Institute, "The results indicated that the as-deposited films were Ti-C-x-N-y nanocomposite films consisting of the nanocrystalline Ti(C,N) embedded in amorphous carbon matrix. A pronounced crystalline phase was observed in the film with high Ti and N contents. The film hardness and elastic modulus decreased with the increase of C/Ti arc current ratio, and a maximum hardness of 37 GPa was obtained with the Ti content of 45.6 at.% and the N content of 38.8 at.%."

According to the news editors, the research concluded: "At high carbon concentration, the films exhibited amorphous structure and more disordered C-C and C-N soft phases were produced with less Ti incorporated into the film."
