Caracterização do comportamento de desgaste de cerâmicas de alumina densa : efeitos de parâmetros do ensaio do tipo pino no disco
(Universidade Federal de São Carlos, 2010-12-08)
Searching for wear resistant materials, attention has been paid to Si3N4, SiC, Al2O3 and ZrO2 ceramics due to their better properties as compared to other materials. Although ceramic are brittleness, improvements on the ...
Desenvolvimento de blendas poliméricas policarbonato/ poli (Tereftalato de Butileno) (PC/PBT) compatibilizadas e nanoestruturadas
(Universidade Federal de São Carlos, 2012-03-08)
The evaluation of addition of a random copolymer as compatibilizing and his effect in obtaining nanostructured morphology in blends composed by PC as matrix and PBT as dispersed phase, were investigated. The copolymercom ...
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 ...
Avaliação do reprocessamento de copolímero SAN através de moldagem por injeção
(Universidade Federal de São Carlos, 2011-06-30)
The main objective of this work was to study the reprocessing of copolymer SAN through injection molding and its influence on the mechanical, thermomechanical and optical behavior of that copolymer. Mechanical properties, ...
Influência da nanoargila no envelhecimento higrotérmico de compósitos de polipropileno / PP maleado / fibra de vidro
(Universidade Federal de São Carlos, 2010-05-21)
In short glass fiber (GF) reinforced polypropylene (PP) composites, despite of the chemically inert and non-polar nature of the matrix, the fiber-matrix interfacial integrity may be compromised in a hygrothermal active ...
Síntese, sinterização em forno de micro-ondas e caracterização da Fe-Ni, PZT e do sistema multifuncional magnetoelétrico PZT/Fe-Ni
