Transition metal nitride coatings films such as TiN or ZrN have been extensively studied for industrial applications. Residual stresses of the coatings generally affect the mechanical behaviour and the corrosion resistance and hence the performance of the product. The development of new, fast and simple methods for the assessment of residual stresses is then of great importance for coating tech...

Modifications in texture and surface chemistry are commonly used to increase the biologic response to implants. We evaluated the influence of five different acid etching treatments on the chemical and topographical superficial characteristics of cpTi grade IV discs (test groups). One group of samples were only polished (control group). The samples were analyzed by electron microscopy (SEM, EDS)...

A new approach for SrBi2Nb2O9 (SBN) thin ®lms synthesis using aqueous solution was successfully experienced. The deposition solution was prepared from Sr±Bi±Nb mixed-citrate solution, requiring no special atmosphere and using common reagents. Films were deposited by dip coating onto Pt/Ti/SiO2/ Si(100) substrates and heat treated at temperatures ranging from 300 to 700 C. The process of formati...

Abstract The effect of chemical substances is reported on the structure, surface morphology, and material properties vanadium oxide thin films. study concentrated effects initial materials (e.g., NH 4 VO 3 , NaVO 2 vanadyl acetylacetonate, ammonium decavanadate) various additives acids, chelate ligand, reduction reagent, tensides). syntheses are based sol-gel chemistry. important aim technique ...

Aluminum nitride (AlN) thin films were deposited on Si (100) substrates by using plasma-enhanced atomic layer deposition method (PEALD). Optimal PEALD parameters for AlN deposition were investigated. Under saturated deposition conditions, the clearly resolved fringes are observed from X-ray reflectivity (XRR) measurements, showing the perfectly smooth interface between the AlN film and Si (100)...

A series of In2O3 thin films, ranging from X-ray diffraction amorphous to highly crystalline, were grown on amorphous silica substrates using pulsed laser deposition by varying the film growth temperature. The amorphous-to-crystalline transition and the structure of amorphous In2O3 were investigated by grazing angle X-ray diffraction (GIXRD), Hall transport measurement, high resolution transmis...

In this paper, a positive effect of rapid thermal annealing (RTA) technique has been researched and compared with conventional furnace annealing for Si nanocrystalline in silicon carbide (SiC) matrix system. Amorphous Si-rich SiC layer has been deposited by co-sputtering in different Si concentrations (50 to approximately 80 v%). Si nanocrystals (Si-NC) containing different grain sizes have bee...

The crystallization and distribution the features of Pt, Pd Pt/Pd nanoparticles in spin-on glass SiO2 films were studied within a wide range dopant concentrations silica sol (from 10 to 80 mol.% or per 100 Si). grazing incidence X-ray diffraction (GIXRD) characterization revealed that formation 4–8 nm sized crystalline began at least Pt and/or Si. obtained from sols with lower characterized by ...
