Effect of structural singularities on superwettability of SiO₂-based coatings
(Universidade Federal de São Carlos, 2019-11-07)
A detailed study on the correlation between structural singularities and wettability of neat and chemically modified coatings prepared from layer-by-layer (LbL) assembled silica nanoparticles (SiO₂) was performed. ...
Otimização das propriedades mecânicas da liga de alumínio 319 contaminada com ferro
(Universidade Federal de São Carlos, 2019-02-15)
The influence of iron additions (0.6, 0.8, 1.2 and 1.5 wt.%) and heat treatment on the microstructure and tensile properties of the 319-aluminum alloy processed by spray forming and rotary swaging was investigated. The ...
Indicadores de produção científica para prospecção tecnológica em manufatura aditiva de biocerâmicas
(Universidade Federal de São Carlos, 2019-05-31)
In the Bone Tissue Engineering, biomaterials are used as scaffolds to produce a support and cell growing. Because of the similarity to the bones cells, ceramic compounds are the main materials used to produce the scaffold. ...
Estudo da indução da grafitização da resina fenólica fenol/formaldeído
(Universidade Federal de São Carlos, 2019-08-14)
Among the probable carbon sources, there are the polymers, as the phenolic resin, which produces residual carbon around 60% wt./wt. after thermal treatment. It is classified as non-graphitizable, because it has not graphitic ...
Refill friction stir spot welding: investigation of the similar and dissimilar welding of AA5754-H22 and AA6061-T6 sheets
(Universidade Federal de São Carlos, 2019-06-03)
The automotive industry is shifting to a new paradigm of material utilization in vehicles. Different parts of the car structural body are increasingly being made of materials selected to have a customized performance ...
Desenvolvimento de cerâmicas refratárias engenheiradas densas e porosas
(Universidade Federal de São Carlos, 2019-09-04)
High temperature processes are of great importance as they are widely applied in the manufacture of commodities, consumer goods and advanced materials. For these processes to be possible, the thermal environment in which ...
O efeito dos tratamentos térmicos na microestrutura e nas propriedades mecânicas de rodas automotivas fundidas a baixa pressão na liga A356
(Universidade Federal de São Carlos, 2019-12-13)
The low-pressure die casting process to produce automotive aluminum alloy wheels is well known, and, in the last decades, has been consolidated as the most common way to produce light automotive wheels in large scale. The ...
Caracterização em tempo real da birrefringência de forma do sistema PS/PP por técnica reo-óptica
(Universidade Federal de São Carlos, 2019-02-25)
The rheo-optical behavior of polystyrene (PS), polypropylene (PP) and immiscible dilute mixtures of these polymers was studied in order to determine the flow birefringence and form birefringence of these materials. The ...
Identificação de um modelo viscoelástico para o comportamento de relaxação de tensões do PTFE sob compressão e em temperatura ambiente
(Universidade Federal de São Carlos, 2019-08-29)
The identification of viscoelastic models is important for the design of polymeric parts by making the mechanical behavior of the material predictable under critical conditions. However, the characterization of this behavior ...
Estudo de ligas Ti-Nb-Zr e Ti-Nb-Mg, fundidas e na forma de recobrimentos sobre aço inoxidável, para aplicações biomédicas
(Universidade Federal de São Carlos, 2019-10-31)
In the present thesis, nanostructured coatings of Ti (100 - (20 + z)) -Nb20-Xz alloys (X = Zr and Mg) were produced by sputtering. So with that, it was possible to analyze the effect of the addition of Zr and Mg on the ...
