Evaluation of CrAlN multilayered coatings deposited by PVD magnetron sputtering

Oleophobic optical coating deposited by magnetron PVD

Thin oxinitride films of Zn-Sn-O-N and Si-Al-O-N were deposited on glass by reactive magnetron sputtering at various nitrogen-to-oxygen ratios. Nitrogen added to oxygen led to decrease of the surface roughness and increase of oleophobic properties studied by the oil-drop test. The best oleophobity was obtained for Zn-Sn-O-N oxinitride at Zn:Sn=1:1 and N:O=1:2. Improved oleophobic properties wer...

INVESTIGATION OF THE GROWTH MECHANISMS OF a-CHX COATINGS DEPOSITED BY PULSED REACTIVE MAGNETRON SPUTTERING

The study of the growth mechanisms of amorphous hydrogenated carbon coatings (aCHx) deposited by reactive pulsed magnetron discharge in Ar+C2H2, Ar+H2 and Ar+C2H2+H2 low pressure atmospheres is presented in this work. Hydrogen-containing species of the reactant gas affect the microstructure and surface properties of the a-CHx thin films. The dynamic scaling theory has been used to relate the ma...

Synthesis and characterization of La2NiO4+δ coatings deposited by reactive magnetron sputtering using plasma emission monitoring

Optimization Studies of Photocatalytic Tungsten-Doped Titania Coatings Deposited by Reactive Magnetron Co-Sputtering

In this article we investigate the structural and photocatalytic properties of W-doped titanium dioxide coatings. TiO2-W thin films were deposited onto glass slides by reactive magnetron co-sputtering. The properties of the films were analyzed using such techniques as XRD, Raman spectroscopy, EDX, TEM, and surface profilometry. The photocatalytic properties of the coatings were assessed using t...

Bioactivity response of Ta1-xOx coatings deposited by reactive DC magnetron sputtering.

The use of dental implants is sometimes accompanied by failure due to periimplantitis disease and subsequently poor esthetics when soft-hard tissue margin recedes. As a consequence, further research is needed for developing new bioactive surfaces able to enhance the osseous growth. Tantalum (Ta) is a promising material for dental implants since, comparing with titanium (Ti), it is bioactive and...
