Ligas de TiNbZr com superfícies bioativas: caracterização topográfica e avaliação do contato ósseo in vivo
(Universidade Estadual Paulista (Unesp), 2017-03-17)
O foco principal deste estudo centrou-se sobre as propriedades da superfície do titânio comercialmente puro, Ti6Al4V e novas ligas de TiNbZr, quando empregada técnica de modificação de superfície por anodização anódica com ...
Corrosion behaviour of polycrystalline Nb2O5 thin films and its size effects
(2016-01-01)
This study examines the effect of film thickness ranging from 230 to 404 nm on the corrosion resistance of Nb2O5 thin films grown by chemical solution deposition. The films were characterized to obtain the relationships ...
Oxide coating containing apatite formed on Ti-25Nb-25Ta alloy treated by Two-Step Plasma Electrolytic Oxidation
(Elsevier B.V., 2020-01-25)
Hydroxyapatite (HA) is a bioactive calcium phosphate capable of enhancing the implant/bone connection improving osteoconductivity and osseointegration process. However, the HA presents mechanical properties limiting its ...
Surface Microstructure Modification in Square Extruded Al-Nb Powder Composites by Shot Peening
(IOP Publishing, 2014-10)
75%Al-25%Nb powder composites, fabricated by square shape cold extrusion, were subject to shot peening treatment with full coverage. Shot peening results in a high number of intense local deformations, with a surface ...
