Titanium dioxide (TiO2) thin films are widely used in transparent optoelectronic devices due to their excellent properties, as well photocatalysis, cosmetics, and many other biomedical applications. In this work, TiO2 were deposited onto AISI 304 316L stainless steel substrates by atomic layer deposition, followed comparative evaluation of the mixture anatase rutile phase X-ray diffraction, Ram...

: In this work, a new approach for the one-step integration of interdigitated electrodes on macroporous silicon substrates is presented. Titanium/gold interdigitated electrodes are used to pattern p-type silicon substrates prior the anodization in an organic electrolyte. The electrolyte characteristics, conductivity, and pH have been found to affect the adherence of the metal layer on the silic...

To investigate the effect of surface nanostructures on the behaviors of human umbilical vein endothelial cells (HUVECs), surface nanostructured titanium alloy (Ti-3Zr2Sn-3Mo-25Nb, TLM) was fabricated by surface mechanical attrition treatment (SMAT) technique. Field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), transmission electron microscopy (TEM) and X-ray dif...

in this study, hydroxyapatite was coated on titanium substrates by plasma spraying process. a well-known porous and lamellar microstructure was found in the lateral and outer surface of coating. the phase composition was studied by xrd and the morphological and the microstructural aspects were investigated by scanning electron and optical microscopy. the hardness of coatings and substrates was ...

in this investigation, fluor-hydroxyapatite (fha) film was deposited on a titanium substrate by sol-gel method. triethyl phosphite, ammonium fluoride and calcium nitrate in ethanol solutions were used respectively as p, f and ca precursors. typical apatite structures were obtained for all coatings after dipping and subsequent heat treatment at 550, 700 and 800 ºc, the coating layers were invest...

This paper deals with the interfacial adhesion properties of Ti-6Al-4V alloy substrates, prepared by using different treatment protocols selected on basis their effectiveness, and bonded a structural, high-strength epoxy adhesive. The alternative pre-bonding treatments were sodium hydroxide anodization low-pressure-plasma treatment, effects which compared to that base preparation via solvent de...
