Elaboração e implementação piloto de um portal para o apoio à cooperação científica e tecnológica e sua aplicação à área de tratamento de superfícies metálicas.
(Universidade Federal de São Carlos, 2005-12-02)
The globalization and the Communication and Information Technologies
(CIT´s) have been, respectively, increased the demand and facilitated the
existence of cooperation associated to innovation, research and development
(R&D). ...
Processamento viscoplástico e conformação cerâmica por rolos a frio a partir de suspensões concentradas de alumina.
(Universidade Federal de São Carlos, 2005-07-27)
Plastic forming, followed by roll-pressing, allows to shape ceramic bodies with thickness that are useful for electronic and pavement ceramics. This work introduces an alternative route to processing ceramic plastic mixes. ...
Processamento e caracterização de condutores de íons O2- a partir de cerâmicas BIMEVOX.
(Universidade Federal de São Carlos, 2005-11-11)
In this work, the processing of BIMEVOX family ceramics (ME-doped bismuth vanadate, ME =Cu2+, Fe3+ and Ti4+), obtained by precursor oxides fusion method was studied. The resulting powders were valued by X ray diffraction, ...
Determinação da energia de fratura em materiais cerâmicos em altas temperaturas.
(Universidade Federal de São Carlos, 2005-03-11)
In this work, the main objective was to determine the energy of fracture in
ceramic materials, focused on refractories, at high temperatures and to inquire
the interference of the creep on this measurement. Therefore, ...
Estudo da transição de fase sólido-vapor e da eficiência de inibidores voláteis de corrosão quando incorporados em matrizes poliméricas
(Universidade Federal de São Carlos, 2005-08-05)
In this work it is proposed a potential barrier model between solid and vapor phases. As a consequence of this model it is developed a method to measure vapor pressure as low as 10-5 Pa. A thermodynamic system consisting ...
Uso do método do trabalho essencial de fratura (EWF) para avaliar a tenacidade de blendas poliméricas.
(Universidade Federal de São Carlos, 2005-03-11)
Initially it was made a well elaborated study on the essential work
of fracture method (EWF) using the polyamide 6 (PA6) because this polymer
shows high difficult to evaluate its toughness. The PA6 is a semi-crystalline
polymer, ...
Microestrutura e propriedades mecânicas de ligas Al-Si hipoeutéticas conformadas por spray.
(Universidade Federal de São Carlos, 2005-06-29)
The aims of this work were the microstructural and tensile properties
characterization of the hypoeutectic spray formed Al-Si 319 and 380 alloys. The
alloys were melted by induction furnace, gas atomized with nitrogen ...
