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...

in this research, tribological behavior of ti-ni-p intermetallic coatings on titanium substrates have been investigated under dry reciprocating conditions. hardness profile testing results exhibit that high surface hardness has been attained and static indentation result shows that the intermetallic coating has better adhesion strength than the conventional ceramic coatings. in this respect, th...

low carbon steel samples were both shot into and inoculated with titanium in order to improve mechanical properties such as strength and toughness. sem observations and x-ray analyses revealed that titanium nitride and titanium carbonitride precipitates being scattered in the ferrite substrate reduce the grain size in all as-cast, heat-treated and as-rolled cases. the growth of the grains at hi...

objective(s):anodized treated titanium surfaces, have been proposed as potential surfaces with better cell attachment capacities. we have investigated the adhesion and proliferation properties of h9c2 cardiac myoblasts on anodized treated titanium surface.  materials and methods: surface topography and anodized tubules were examined by high-resolution scanning electron microscopy (sem). control...

The effect of titanium dioxide addition on bonding strength of CaO-P2O5 -Na 2O-TiO2glass-ceramic system was investigated as a coating on titanium substrate. Thus, different amounts of TiO2 (2, 3.5 and 5mol %) were added to the base glass batch composition. The prepared glaze slips were applied on the substrate by dip coating method, dried and then heat treated at various temperatures. After tha...

We deposited a lead zirconate titanete (PZT) polycrystalline film on a titanium substrate by the hydrothermal method and fabricated a transducer using the PZT film for use as an ultrasound probe. A 10MHz miniature one-dimensional-array medical ultrasound probe containing the PZT film was developed. After sputtering titanium on the surface of a hydroxyapatite substrate, the titanium film on the ...

This study examined the characteristics of calcium phosphate coatings formed on untreated and H2O2-treated titanium substrates by electrodeposition in a modified simulated body fluid (SBF). A porous coating comprising of mainly hydroxyapatite (HA) was formed on the H2O2-treated titanium substrate by electrodeposition. This coating was transformed into carbonate and calcium-deficient HA layers w...

the synthesis of titania via sol-gel method has been widely studied. in the present work, titania was deposited onto a titanium substrate via sol-gel method. different processing parameters such as the repetition number of dipping/heat treatment process and dipping time have been studied to obtain the homogenous titania coating. phase and microstructural evaluation of the powder and coating sam...
