Oxidation kinetics of commercially pure titanium [PDF]

open access: yesMatéria (Rio de Janeiro), 2007
The aim of this work was to perform thermal characterization of commercially pure titanium in dry air to determine its oxidation kinetics and the structure of the oxide. The oxidation kinetics were determined thermogravimetrically under isothermal conditions in the temperature range 300 to 750 ºC for 48 hours and the structure of the oxides was ...

Machinability of Nano-Structured Biomaterials for Dental Implants

open access: yesCommunications, 2014
High quality materials are characterized by increased wear resistance, high strength and hardness, abrasive wear resistance, heat and creep resistance. Due to these properties some materials are considered as hard to machine.

The role of titanium in electromigrated tunnel junctions

open access: yes, 2014
A standard route for fabrication of nanoscopic tunnel junctions is via electromigration of lithographically prepared gold nanowires. In the lithography process, a thin adhesion layer, typically titanium, is used to promote the adhesion of the gold ...

The contribution of grain boundary barriers to the electrical conductivity of titanium oxide thin films [PDF]

open access: yes, 2008
Titanium oxide thin films were prepared by reactive magnetron sputtering. The reactive gas pulsing process was implemented to control the oxygen injection in the deposition process and,consequently, to tune the oxygen concentration in the films from pure

Surface modification of structural materials by low-energy high-current pulsed electron beam treatment [PDF]

open access: yes, 2002
Microstructure formation in surface layers of pure titanium and ferritic-martensitic steel subjected to electron beam treatment is studied. It is shown that low energy high-current pulsed electron beam irradiation leads to the martensite structure within

Calcium Phosphate Formation on Ti-Ag Alloys in Simulated Body Fluid

open access: yesJournal of Biomechanical Science and Engineering, 2009
Ti-Ag alloys with 20 and 25 mass% Ag were prepared; their surfaces were polished using silicon carbide abrasive papers. The polished alloys were immersed in a simulated body fluid (SBF), and their surfaces were observed by scanning electron microscope ...
