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, ...
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 ...
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 ...
Processamento e caracterização de ligas a base de magnésio para uso como implantes bioabsorvíveis
(Universidade Federal de São Carlos, 2015-02-23)
Magnesium alloys have attracted great interest for use in temporary orthopedic implants to replace existing materials, due to the combination of physical, mechanical and corrosive properties. A magnesium based alloy ...
Obtenção de nanofibrilas de celulose de árvores pioneiras amazônicas e processamento de nanobiocompósitos de PHBV/nanofibrilas de celulose de eucalipto no estado fundido
(Universidade Federal de São Carlos, 2014-11-24)
This research project aimed to develop high value-added products such as
biodegradable composites reinforced with cellulose nanofibrils (CNF) making use of
Amazonian pioneer plant species, useful in restoration of degraded ...
Influência de aditivos pró-degradantes nas degradações abiótica e biótica do polietileno de alta densidade
(Universidade Federal de São Carlos, 2015-03-06)
High density polyethylene (HDPE) is widely used in the manufacture of
packaging disposables and in order to minimize the environmental impact
caused by disposal, have been incorporated, into the HDPE, additives that
promises ...
Desenvolvimento e caracterização de tecidos vítreos flexíveis altamente bioativos
(Universidade Federal de São Carlos, 2015-10-26)
Bioactive glasses were developed by Hench in 1969, and are widely known to have the ability to rapidly form a chemical bond with hard and soft living tissues. Currently, these glasses have been used clinically as biomaterials ...
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 ...
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 ...
