Soldagem pontual por fricção (FSpW) de poliamida 6
(Universidade Federal de São Carlos, 2015-08-03)
Friction Spot Welding (FSpW) is an innovative technique developed and
patented in 2005 by the Helmholtz Zentrum Geesthacht (HZG) research center
in Germany. FSpW uses the friction between a rotating tool and the ...
Expansão por umidade de revestimentos cerâmicos : métodos de medida e variáveis envolvidas
(Universidade Federal de São Carlos, 2015-08-05)
The expansion by humidity (EPU) is characterized by the increase in the size of the ceramic body when in contact with water in liquid or vapor. The phenomenon can contribute to the development of severe pathologies in ...
A importância da caracterização do módulo de elasticidade e do amortecimento de refratários por técnica dinâmica
(Universidade Federal de São Carlos, 2013-03-08)
This dissertation tries to understand the mechanisms involving damping phenomenon in ceramic refractory materials, using a dynamic technique. Damping proves to be an interesting parameter to analyze thermal shock damage ...
Turbidimetria in-line na quantificação do tamanho de partícula de misturas poliméricas na extrusão
(Universidade Federal de São Carlos, 2017-10-16)
The morphology of mixtures and polymeric compounds is usually evaluated by off-line characterization methods, which require time for sample preparation and analysis of results. In-line rheo-optical characterization techniques ...
Estudo da curvatura central das placas cerâmicas para revestimentos : a influência da fusibilidade e coeficiente de expansão térmica da camada de engobe nas curvaturas desenvolvidas durante e após a queima
(Universidade Federal de São Carlos, 2017-09-05)
Most ceramic tiles have a slip layer and this has a significant influence on the characteristics of the ceramic tiles. In contrast to this reality, the specialized literature on engobes is sparse and superficial. It is ...
Estudo da influência de argilitos e feldspatóides em composições de porcelanato
(Universidade Federal de São Carlos, 2011-03-03)
Considering the various types of ceramic tiles used today, the stoneware tile is distinguished by its aesthetic and technical characteristics, such as: very low water absorption (less than 0.5%), high mechanical strength, ...
Friction riveting of aluminium alloy 6056-T6 with short-glass-fiber-reinforced polyamide 6 composite
(Universidade Federal de São Carlos, 2017-08-11)
Friction Riveting (FricRiveting) is a relatively new joining technique for metal-polymer hybrid structures. This master thesis was carried out to investigate the FricRiveting process for polyamide 6 reinforced with 30 wt% ...
Avaliação da resistência ao desgaste de aços inoxidáveis conformados por spray
(Universidade Federal de São Carlos, 2011-08-03)
The aim of this work was the study of the microstructure and the wear resistance of two stainless steels, the ferritic-AIF with 27% Cr and the superduplex-SDM modified with boron (3.5% wt.), processed by spray forming. The ...
Avaliação da tendência à formação de fase vítrea nas ligas à base de alumínio do sistema Al-Y-Fe
(Universidade Federal de São Carlos, 2009-08-03)
The present work aimed to study the glass-forming ability of the aluminum-itrium-iron (Al-Y-Fe) alloys. The work included the preparation of samples through the melt-spinning technique and varying the composition of the ...
Fundamentos, experimentos e simulação de tintas térmicas para aplicação em fornos cerâmicos
(Universidade Federal de São Carlos, 2019-03-13)
Regarding the current need of higher sustainability and cost reductions of
industrial processes, some require high amounts of energy due to the high
temperatures involved being siderurgy a good example. In these scenarios ...
