Wear Behavior of Ti-Al2O3 Biocomposites in 9 g/L NaCl Solution
(2019-10-01)
Ti-based biocomposites reinforced with Al2O3 particles were processed by powder metallurgy. Wear behavior was investigated by reciprocating wear tests in 9 g/L NaCl solution. The effect of Al2O3 volume fraction, normal ...

Syntheses of bismuth titanate templates obtained by the molten salt method
(2013-09-01)
Bismuth titanate templates (Bi4Ti3O12) were synthesized by the molten salt method in Na2SO4 and K2SO4 fluxes, using an amorphous Bi4Ti 3O12 precursor and a mechanically mixed Bi 2O3+TiO2 mixture as the starting materials. ...
Human alveolar bone cell proliferation, expression of osteoblastic phenotype, and matrix mineralization on porous titanium produced by powder metallurgy
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Objective: This study aimed at investigating the influence of the porous titanium (Ti) structure on the osteogenic cell behaviour. Materials and methods: Porous Ti discs were fabricated by the powder metallurgy process ...
Reverberatory furnaces in the Puna of Jujuy, Argentina, during colonial times (from the end of the 16th to the beginning of the 19th century A.D.)
(Academic Press Inc., 2017-12)
This paper presents the study of the extractive metallurgical technology that was employed in four colonial mining-metallurgical sites in the high plateau (Puna) of Jujuy, Argentina, dedicated to silver exploitation during ...
Ancient metalworking in South America: A 3000-year-old copper mask from the Argentinian Andes
(Antiquity Trust, 2017-06)
Metallurgy in pre-Columbian America first developed in the Andes, and Peru has long been considered to be the initial point of origin. The recent discovery of an anthropomorphic copper mask in north-west Argentina, however, ...
Nanoquasicrystalline Al-Fe-Cr-Nb alloys produced by powder metallurgy
(Elsevier, 2013-10)
Nano-quasicrystalline Al-Fe-Cr based alloys produced by rapid solidification processes exhibit high strength at elevated temperatures. Nevertheless, the quasicrystalline particles in these systems become unstable at high ...
