Spray forming of wear and corrosion resistant bimetallic pipes : from the alloy design to the semi- industrial process
(Universidade Federal de São Carlos, 2016-02-29)
The oil exploitation and production at the pre-salt fields in a safety and efficient
way depends on the development of materials that withstand the severe work
conditions found in these fields. For instance, pipes, such ...
Comportamento mecânico em fadiga da liga de titânio beta metaestável Ti-5553
(Universidade Federal de São Carlos, 2016-10-14)
The microstructure of metastable beta Ti alloys is a decisive factor that
governs their properties and, therefore, the assessment of the relation between
the microstructure and the fatigue response means an advance in ...
Abordagem termodinâmica do transporte iônico e da relaxação estrutural em vidros fosfatos de prata
(Universidade Federal de São Carlos, 2016-09-12)
Ionic conductivity in glasses was first discovered and demonstrated by
Warburg in 1884, but although it has been studied for over a century, the
mechanisms underlying ionic conduction in glasses are not yet entirely ...
Estudo do processo de soldagem a ponto por fricção de juntas dissimilares entre ligas de alumínio e titânio
(Universidade Federal de São Carlos, 2016-12-09)
Multimaterial structures between aluminum and titanium alloys are a
technologically attractive field of research and their increasing use in the
transportation sector for weight and emission reduction is part of the ...
Zircônia CO-dopada por compensação de cargas nos sistemas (ZrO2)1-(x+y)(InO1,5)x(MOz)y com MOz = TaO2,5, NbO2,5, MoO3 ou WO3, como revestimento para barreira térmica
(Universidade Federal de São Carlos, 2016-09-30)
InO1.5-stabilized zirconia (InSZ) is a potential hot corrosion resistant thermal
barrier coating (TBC). However, the thermal instability prevents real applications
of InSZ-based TBC. This thesis investigates the hypothesis ...
Deformação piroplástica em porcelanatos
(Universidade Federal de São Carlos, 2016-09-09)
In recent years porcelain stoneware tiles showed the highest growth in
production and consumption in ceramic industry sector. To achieve low
porosity, which ensures the high performance of the product, is required ...
Avaliação da cinética de degradação abiótica do polietileno de alta densidade, na presença e ausência de aditivo pró-degradante e estabilizantes
(Universidade Federal de São Carlos, 2016-11-28)
The convenience of single-use packaging of high density polyethylene (HDPE) led to the need to convert them into biodegradable materials in less time to minimize the environmental problems caused by disposal. An alternative ...
Eletrólitos sólidos homogêneos e heterogêneos : obtenção e caracterização visando aplicação em células A combustível de temperatura intermediária
(Universidade Federal de São Carlos, 2016-03-04)
Emission reduction of greenhouse gases to the atmosphere in order to control global warming is an urgent need fully accepted by the international community. Ceramic materials play an important role in the possible solutions ...
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 ...
Síntese in situ pelo método Pechini de compósitos magnetoelétricos SBN/NFO para o controle do crescimento anormal dos grãos da fase SBN
(Universidade Federal de São Carlos, 2016-10-19)
A study was made of the synthesis and processing of magnetoelectric particulate composites of strontium barium niobate (SrxBa1-xNb2O6, or simply SBN) as a lead-free piezoelectric phase and nickel ferrite (NFO) as a magnetic ...
