Estudo da resistência à corrosão em ligas de memória de forma NiTiNb com diferentes teores de Nb
(Universidade Federal de São Carlos, 2018-11-26)
In this work, the corrosion behavior of NiTiNb shape memory alloys (SMA) in aqueous medium containing chloride ions was characterized. The study was performed in alloys of six different compositions, which were melted in ...
Sinterabilidade, desenvolvimento microestrutural e caracterização elétrica do BaCe0,9Y0,1O3-ẟ nanométrico obtido por mistura de óxidos
(Universidade Federal de São Carlos, 2018-11-28)
In this thesis, we investigated the microstructural development of BaCe0,9Y0,1O3-ẟ starting from aggregate-free submicrometric and nanometric powders. The differential of these powders is that synthesis occurred via ...
Estudo dos efeitos da substituição de Feldspato por Filito em massas de porcelanato
(Universidade Federal de São Carlos, 2018-11-21)
Porcelain stoneware tiles, porcelanatos, present excellent technical and aesthetic characteristics. In Europe, the bodies used in the manufacture of porcelain and porcelanatos are based on the classic triaxial ceramic, ...
Estudo de filmes de poli(ácido lático) obtidos por fiação por sopro em solução reforçados com nanocristais de celulose
(Universidade Federal de São Carlos, 2016-07-15)
Solution blow spinning is a technique to produce micro- and nano-scale fibers, forming films with high porosity and surface area. Chemical modifications or the incorporation of nanostructures in these fibers can improve ...
Seleção de aditivos de sinterização e processamento cerâmico visando otimização da microestrutura do eletróllto sólido BaZr0,8Y0,2O3-δ
(Universidade Federal de São Carlos, 2018-11-12)
In this thesis, we investigated the production of Yttrium-doped Barium Zirconate
proton-conducting electrolytes with 20 at.% of Yttrium (BaZr0.8Y0.2O3-δ) via solid state
reaction. The great challenge presented by this ...
