Thermally induced liquid-phase deposition method was employed to produce a thin hydroxyapatite (HA) film on a titanium substrate in a metastable calcium phosphate solution. Titanium foil of 100x10x0.02 mm3 was used as a substrate. Prior to HA coating, the substrate was immersed in 5 M NaOH solution at 60 degrees C for 24 hours. Substrate temperature was kept constant at 60 degrees C for 0.5-3 h...

In order to improve the oxidation resistance of ferritic stainless steel, it is possible to deposit a protective coating on steel substrate. In this research through the usage of pack cementation method a coating of titanium was applied on the surface of AISI 430 stainless steel. Scanning Electron-Microscopy (SEM), Energy- Dispersive X-ray spectrometry (EDAX) and X-ray diffraction (XRD) were us...

This paper reports a new packaging method for a wide range of MEMS for application on both the wafer and device scale. Titanium is used as the packaging material in this work and both silicon and titanium MEMS devices are integrated on to a titanium substrate. A Nd:YAG pulsed laser is used to micro-weld the titanium cap to the substrate. A three-dimensional time dependent model of heat flow dur...

Supercritical water was used as a modification method of electrochemically deposited apatite on pure titanium. The apatites were coated on a commercially pure titanium plate using a hydrothermal-electrochemical method. A constant direct current at 12.5mA/cm2 was loaded for 1hr at 25, 60, 100, 150 and 200•Ž in an electrolyte containing calcium and phosphate ions. The deposited apatite on the tit...

     The synthesis of titania via sol-gel method has been widely studied. In the present work, titania was deposited onto a titanium substrat...

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). Contro...

Titanium nitride thin films are used in applications such as tribological layers for cutting tools, coating of some medical devices (scalpel blades, prosthesis, implants etc.), sensors, electrodes for bioelectronics, microelectronics, diffusion barrier, bio-microelectromechanical systems (Bio-MEMS) and so on. This work is a comparative study concerning the influence of substrate temperature on ...

We developed a new building block for constructing planar microwave circuitry: bulk titanium waveguide. The waveguide is formed by deep trench etching, dielectric gap filling, and planarization. The high aspect ratio of the resulting structure provides superior field confinement, low crosstalk, therefore a small footprint. To enable bulk titanium as a substrate compatible with microfabrication,...
