Development of silicon carbide substrates for aerospace applications
(2012-05-22)
Payload and high-tech are important characteristics when the goals are aerospace applications. The development of the technologies associated to these applications has interests that transcend national boundaries and are ...
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 ...
Flow evolution of a metallic slurry during thixoextrusion of an automotive valve
(2004-12-01)
The aim of this work is to characterize a metallic slurry (Al-4.5%Cu) flow during thixoforming of an automotive valve. The necessary globular structure was obtained by first inoculating the alloy with TIBAL (5%Ti, 1%B, Al ...
The effect of iron (Iii) co-insertion in magnesium-aluminum hydrotalcites obtained by precipitation method at ph 11
(2018-01-01)
Hydrotalcite are anionic clay material presenting LDH arrangement and high porosity and specific areas, which make it a good adsorbent for pollutant species in water. Besides that, that material type can be used as catalyst ...
Morphological and structural analyses in carbonated magnesium-aluminum hydrotalcites co-substituted with iron iii
(2018-01-01)
Magnesium-aluminum hydrotalcites can be co-substituted with others trivalent cations, such as iron III in aluminum site, which can be a promising way to modify the properties of that synthetic adsorptive material. In the ...
Microstructure of ceramics TiO2 obtained by protein consolidation
(2012-11-26)
Porous ceramics can be produced by adding starch (corn, potato) and protein (animal or vegetable) to raw material as pore forming element. In this study, titanium dioxide ceramics were formed by vegetable protein consolidation. ...
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 ...
