Comportamento mecânico da liga Ti-6Al-4V com superfície modificada por laser de femtosegundo para uso biomédico
(Universidade Federal de São Carlos, 2012-02-10)
Stainless steel orthopedic implants are still the most widely used in Brazil
due to their lower cost. There is, however, a tendency to expand the use of
special alloys such as titanium-based, due to clinical advantages ...
Processos difusionais, cristalização e escoamento viscoso em dissilicato de bário vítreo
(Universidade Federal de São Carlos, 2014-04-24)
In this work, we analysed if the viscous flow successfully describes the transport of crystal nucleation and crystal growth structural units that occur at the liquid/crystal interface. In order to do this, we calculated ...
Comportamento em fadiga de hastes femorais para artroplastia de quadril com superfícies modificadas
(Universidade Federal de São Carlos, 2015-07-20)
Nowadays, titanium and its alloys are the materials of choice for the
production of implants for hip arthroplasty, a surgery that aims for the
improvement of the quality of life of patients that bear articular pathologies ...
Análise do comportamento termomecânico e da evolução microestrutural durante a laminação de tiras a quente de aços C-Mn via DEFORM™ 3D
(Universidade Federal de São Carlos, 2015-02-26)
Improving the steel processing is a major focus of the metallurgical industry because
the need of materials and products with lower weight and more strength,
in addition to increasingly stringent specifications imposed ...
União pontual por fricção (“friction spot joining”) de alumínio 6181-T4 com compósito laminado de poli(sulfeto de fenileno) e fibra de carbono (CF-PPS)
(Universidade Federal de São Carlos, 2015-02-26)
The friction spot joining (FSpJ) emerges as an alternative and innovative
technique for producing polymer-metal hybrid structures. This technique was
developed and patented by HZG / Germany in 2012. The process uses ...
Transporte eletrônico em filmes ultrafinos nanoestruturados : o sistema SNO2:SB
(Universidade Federal de São Carlos, 2015-12-14)
This thesis describes a study of the electronic charge transport properties in antimony-doped tin oxide (ATO) ultrathin films, prepared by two different methods: by colloidal deposition process (CDP) and by pulsed electron ...
Modificação microestrutural da liga de magnésio AZ31 por fricção e mistura a altas velocidades
(Universidade Federal de São Carlos, 2015-07-03)
Due to the current growth in the fossil fuels consumption, there is a great concern about the increase in pollutant emissions. In order to reduce these emissions, research indicates that the decrease in vehicle weight can ...
Agentes mineralizadores e seus efeitos nas características morfológicas e físico-químicas de aluminas calcinadas
(Universidade Federal de São Carlos, 2015-08-31)
Calcination is an important step in the alumina production process, affecting the final properties of the resulting powder and the attained product. Over the previous decades, attempts have been conducted to understand ...
Nanopartículas de Fe3O4 funcionalizadas e nanocompósitos de base epóxi
(Universidade Federal de São Carlos, 2015-12-17)
The use of metal oxide nanoparticles in nanocomposite has provided new
and interesting properties and is one of the most promising areas in composites.
Compatibility between these nanoparticles and polymer matrix is the ...
Influência das condições de eletrodeposição sobre a resistência a corrosão, susceptibilidade à fragilização por hidrogênio e à corrosão sob tensão do aço ABNT – 4340 revestido com liga Zn/Ni
(Universidade Federal de São Carlos, 2011-01-28)
Zinc-nickel alloys were electrodeposited on ABNT 4340 high strength steel in chloride acid media. The effect of the electrolyte composition and electroplating conditions on cathodic efficiency, chemical composition, ...
