Comportamento mecânico da liga Ti-6Al-4V com superfície modificada por laser de femtosegundo para uso biomédico
(Universidade Federal de São Carlos, 2012-02-10)
Stainless steel orthopedic implants are still the most widely used in Brazil
due to their lower cost. There is, however, a tendency to expand the use of
special alloys such as titanium-based, due to clinical advantages ...
Condutividade iônica e atividade termodinâmica em vidros x AgI (1-x) AgPO3, 0 ≤ x ≤ 0,5
(Universidade Federal de São Carlos, 2012-09-14)
The ionic conductivity in solids is known since the 19th century, but the
mechanisms of charge carriers transportation in amorphus solids is not yet fully
known. The control of ths property is especially important for ...
Parâmetros de monitoramento na produção industrial de componentes em zircônia parcialmente estabilizada com óxido de magnésio
(Universidade Federal de São Carlos, 2012-02-08)
Zirconia has been widely applied on production of structural components, mainly due to its great mechanical properties. However, these properties are associated to the zirconia tetragonal and cubic phases, which are stable ...
Desenvolvimento de protótipo de sensor de umidade cerâmico
(Universidade Federal de São Carlos, 2012-08-24)
Humidity sensor is a special type of gas sensor which is sensitive only to H2O molecules. It has a large variety of applications in industrial, household and agricultural equipments. Humidity ceramic sensors have been ...
Avaliação do comportamento mecânico de nanocompósito de PEEK/nHA sob curta e longa duração para aplicação como biomaterial
(Universidade Federal de São Carlos, 2012-04-27)
The main objectives of this dissertation were to study the short (tensile and impact) and long-term (fatigue) mechanical behavior of nanocomposites of poly(ether-ether-ketone), PEEK, with nanohydroxyapatite, nHA, for ...
O revestimento refratário e seu efeito na vida útil e no consumo energético de calcinadores de alumina
(Universidade Federal de São Carlos, 2012-07-25)
The increased need of reducing production costs of commodities raised the importance of reaching higher levels of process efficiency and also the consolidation of financial gains due to larger-scale production capacities. ...
Caracterização das camadas formadas pela nitretação a plasma de ferro sinterizado
(Universidade Federal de São Carlos, 2012-03-06)
Ion nitriding is a process of thermo-physical-chemical treatment that provides a surface hardening, originated by interstitial diffusion of nitrogen on the ferrous and nonferrous alloys surfaces. Understanding and controlling ...
