Journal ArticleDOI
Mg-Zn-Ca amorphous alloys for application as temporary implant: Effect of Zn content on the mechanical and corrosion properties
T.B. Matias,T.B. Matias,Virginie Roche,Ricardo P. Nogueira,Ricardo P. Nogueira,Gabriel Hitoshi Asato,C.S. Kiminami,Claudemiro Bolfarini,Walter José Botta,Walter José Botta,A.M. Jorge,A.M. Jorge +11 more
TL;DR: In this paper, two Mg-Zn-Ca amorphous alloys were processed and their mechanical and corrosion properties were evaluated and compared, and the effect of Fe content, a typical contaminant in Mgbased alloys, was also evaluated.
Journal ArticleDOI
Surface anodization of the biphasic Ti13Nb13Zr biocompatible alloy: Influence of phases on the formation of TiO2 nanostructures
Diego Alfonso Godoy Pérez,Diego Alfonso Godoy Pérez,Alberto Moreira Jorge Junior,Alberto Moreira Jorge Junior,Gabriel Hitoshi Asato,Jean-Claude Leprêtre,Virginie Roche,Claudemiro Bolfarini,Walter Jose Botta,Walter Jose Botta +9 more
TL;DR: In this article, the anodization of the biphasic (α'+β) Ti13Nb13Zr alloy form arrays of TiO2 nanotubes with well-defined circular geometry in the α′ phase, while nanopores ofTiO2 are formed in the β phase.
Journal ArticleDOI
Processing and characterization of amorphous magnesium based alloy for application in biomedical implants
Telma Blanco Matias,Gabriel Hitoshi Asato,Bruno Torquato Ramasco,Walter José Botta,Claudio Shyinti Kiminami,Claudemiro Bolfarini +5 more
TL;DR: In this paper, a magnesium-based amorphous ternary alloy and its characterization was established using two binary master alloys by melting in an induction furnace, and carbon steel crucible was used in argon atmosphere with and without addition of SF6 gas to minimize the oxygen contamination.
Journal ArticleDOI
Severe plastic deformation and different surface treatments on the biocompatible Ti13Nb13Zr and Ti35Nb7Zr5Ta alloys: Microstructural and phase evolutions, mechanical properties, and bioactivity analysis
Diego Alfonso Godoy Pérez,Diego Alfonso Godoy Pérez,Alberto Moreira Jorge Junior,Alberto Moreira Jorge Junior,Virginie Roche,Jean-Claude Leprêtre,Conrado Ramos Moreira Afonso,Dilermando Nagle Travessa,Dilermando Nagle Travessa,Gabriel Hitoshi Asato,Claudemiro Bolfarini,Walter Jose Botta,Walter Jose Botta +12 more
TL;DR: In this paper, the authors used high pressure torsion (HPT) to form ultrafine-grained (UFG) microstructures in both alloys, resulting in the average size of grains/subgrains of ∼203nm and ∼112nm for the Ti13Nb13Zr and Ti35Nb7Zr5Ta samples, respectively.
Journal ArticleDOI
Changing the solidification sequence and the morphology of iron-containing intermetallic phases in AA6061 aluminum alloy processed by spray forming
L.H. Pereira,Gabriel Hitoshi Asato,Lucas B. Otani,A.M. Jorge,C.S. Kiminami,Claudemiro Bolfarini,Walter José Botta +6 more
TL;DR: In this paper, the solidification of an AA6061 alloy highly contaminated with iron (1.4 wt%) was studied, and spray forming was used to prevent the formation of intermetallic AlFeSi phases with platelet-like morphology, resulting in a final ductile microstructure.
