Production and characterization of porous titanium applied in biomaterial
(2017-01-01)
The development of materials with a porous titanium surface has been widely studied in the field of biomaterials due to the excellent biocompatibility, high corrosion resistance and combination of high strength with low ...
Design Of Al-nb2al Composites Through Powder Metallurgy
(SPRINGERNEW YORK, 2016)
Powder processing and In Vivo evaluation of a titanium porous coating implant
(2004-12-01)
The processing of titanium porous coatings using powder metallurgy technique to achieve a porous structure that allows osseointegration with bone tissue was discussed. The porous microstructure exhibited micropores and ...
Defect-induced photoluminescence of powdered silica glass
(2008-03-27)
Visible photoluminescence was generated in standard soda-lime-silica glass powder, mechanically milled in a high-energy attrition mill. The broad emission band maximum shows a linear dependence on the exciting wavelength, ...
High-Pressure Assisted Sintering of Ti-20Si-10B and Ti-10Si-5B Powders
(Trans Tech Publications Ltd, 2012-01-01)
This work presents the structural characterization of Ti-10Si-5B and Ti-20Si-10B (at-%) alloys produced by high-pressure assisted sintering. Sintering was performed in air at 1100 and 1200 degrees C for 60 s using pressure ...
Production of Ti-35Nb alloy by powder metallurgy for aerospace application
(2004-12-01)
Titanium and its alloys provide high strength-to-weight ratios, good fatigue strength and increased corrosion resistance compared with others materials. Its acceptance in aerospace has been limited by costs considerations ...
