In this study, a low-temperature synthetic approach was developed for the fabrication of calcium hydroxyapatite (CHAp) coatings on titanium substrate. The substrates were first coated with CaCO3 by spin-coating technique using sol–gel chemistry approach, and obtained product transformed into CHAp during dissolution–precipitation reaction. phase purity structural morphological features evaluated...

In order to improve various properties of medical titanium alloys, Ti–3Zr–2Sn–3Mo–25Nb alloy specimens were subjected microarc oxidation (BMAO) in 0.1 mol/l sodium tetraborate electrolyte cover the substrate with a micro-nano double-graded structured coating. The effect time on microstructure, physical phase, hardness, corrosion resistance, and wettability film layer was investigated. results s...

Silver coordination polymer chains were deposited on Au(111) as a model surface, as well as on gold alloy and titanium as dental implant and restorative materials. The topography of the surface was analysed on the model substrate and it was found to be a nano-structured crystalline material. In vitro investigations in a flow chamber imitating the oral environment prove the anti-bacterial proper...

This report shows the analysis of two essential processes in the integrated circuit fabrication: SiO2 growth and metal deposition. The first part consists of the characterization of dry and wet thermal oxidation. The idea is to obtain the parameters that describe the behavior of this process and use this to predict specific oxidation times and thicknesses. The second part consists of metal depo...

Diamond-like carbon deposition techniques, characterization techniques and processing parameters, such as gas ratio, bias voltage, gas pressure, type of precursor gas used, temperature, gas total flow, substrate material, among others are reviewed. Mostly silicon substrates have been employed, but also metallic materials such as titanium and aluminum alloys or steels have been used as well. Imp...
