Análise comparativa de fadiga mecânica em compósitos de polipropileno com talco e com nanoargila
(Universidade Federal de São Carlos, 2010-05-17)
Talc is a well known lamellar mineral filler much used for mechanical reinforcement of polypropylene (PP) composites. Mineral nanoclay is also a lamellar filler that is gaining much interest due to its reinforcement effect ...
Comportamento térmico e mecânico de resinas termocuráveis para aplicação como revestimento adesivo em fios esmaltados
(Universidade Federal de São Carlos, 2010-04-01)
Selfbonding magnet wires are composed by two or more polymeric cover layers, being the inner layers thermosetting and the over coat composed of a thermoplastic cross-linkable layer. These wires are used in several magnetic ...

(Universidade Federal de São Carlos, 2011-10-23)
The aim of this work was to study the production of metal coatings from amorphous alloy Fe-25Cr-7Ni-4,5B (wt.%), with special focus on mechanical and microstructure properties. Initially, preliminary studies were made ...
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 ...
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 ...
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 ...
