Titanium dioxide (TiO2) thin films have generated considerable interest over recent years, because they are functional materials suitable for a wide range of applications. The efficient use the outstanding properties these relies strongly on their basic characteristics, such as structure and morphology, which affected by deposition parameters. Here, we report influence plasma power precursor chemistry growth kinetics, morphology TiO2 grown Si(100) plasma-enhanced atomic layer (PEALD). For...
TiO2/Al2O3 nanolaminates are being investigated to obtain unique materials with chemical, physical, optical, electrical and mechanical properties for a broad range of applications that include electronic energy storage devices. Here, we discuss the nanolaminate structures constructed on silicon (1 0 0) glass substrates using atomic layer deposition (ALD) by alternatively depositing TiO2 sublayer Al2O3 partial-monolayer TTIP–H2O TMA–H2O precursors, respectively. The is formed single cycle, so...
Cobalt-chromium-molybdenum (Co-Cr-Mo) alloy is a material recommended for biomedical implants; however, to be suitable this application, it should have good tribological properties, which are related grain size. This paper investigates the behaviour of Co-Cr-Mo produced using investment casting, together with electromagnetic stirring, reduce its The samples were subjected wear and scratch tests in simulated body fluid (Ringer's lactate solution). Since reduction size can influence material,...
Abstract Metals and their alloys are very important for orthopedic applications, the basic requirements a successful implant chemical stability, mechanical behavior, biocompatibility in body fluids tissues. For prosthesis corrosion resistance of metals is one major prerequisites to avoid impairment material properties due degradation. The combined action wear on called tribocorrosion DLC (Diamond-Like Carbon) films have been extensively studied increase protect from corrosion. Additionally,...
Amorphous silicon oxycarbonitride (SiCxNyOz) films have been deposited on Si substrates by low temperature reactive magnetron co-sputtering of and graphite targets in mixed Ar/N2 atmosphere. Our studies are focused the influence nitrogen incorporation deposition rate, film composition, structure, chemical bonds, electrical resistivity SiCxNyOz investigated profilometry, Rutherford Backscattering Spectrometry (RBS), X-ray diffraction (XRD), Raman spectroscopy, Photoelectron Spectroscopy...
