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 ...
Synthesis and characterization of Biosilicate/F18 bioglass scaffolds for dental application
(Universidade Federal de São Carlos, 2019-10-16)
In this work, Biosilicate scaffolds were synthesized using the foam replica technique. Biosilicate is highly bioactive, biodegradable, antibacterial, and non-toxic. Despite of these properties, Biosilicate scaffolds present ...
Caracterização microestrutural e mecânica da liga AA2024 conformada por spray e processada termomecanicamente
(Universidade Federal de São Carlos, 2019-03-22)
This work aimed to evaluate the possibility of combining spray forming processing with mechanical processing techniques (for instance, extrusion, rotary forging, and equal-channel angular pressing (ECAP)) to be used as ...
Estudo da incorporação de nanopartículas de óxido de zinco e pentóxido de nióbio em polietileno linear de baixa densidade
(Universidade Federal de São Carlos, 2019-03-29)
Linear low-density polyethylene (LLDPE) is one of the most widely used materials in greenhouse covering, due to its low cost and transparency to photosynthetically active radiation up to 80%. However, this polymer also ...
Contribuição para a melhoria no desempenho ambiental de porcelanatos: Avaliação de Ciclo de Vida (ACV) e o uso de fundentes enérgicos
(Universidade Federal de São Carlos, 2019-08-01)
Whether due to growing environmental awareness or legal and market requirements, the quest for sustainable development has leading to the need to improve processes and products. In this scenario, the general objective of ...
Microestrutura, resistência mecânica e corrosão sob tensão em ligas de alumínio Al-0,3%Fe e Al-4%Cu processadas por extrusão em canal angular
(Universidade Federal de São Carlos, 2019-04-29)
Grain refinement is an important hardening mechanism in metallic alloys, notably when the grain size reaches the submicrometer scale. For this purpose, several techniques of Severe Plastic Deformation (SPD) have been ...
Implementação do sistema de cristalização superficial induzida por laser em vidro de composição eutética
(Universidade Federal de São Carlos, 2019-03-01)
The radiation from lasers has been successfully applied to materials
processing such as drilling, cutting and welding, sintering of ceramic oxides,
surface heat treatment, directional solidification of single crystal ...
Aprimoramento de um detector de espalhamento de luz laser em baixo ângulo e seu uso in-line na caracterização morfológica de misturas poliméricas bifásicas
(Universidade Federal de São Carlos, 2019-02-27)
A new prototype of the optical detector based on low angle laser light scattering (LALLS) was developed in order to follow in-line the morphology of polymer blends and composites during processing. For this, light from a ...
Avaliação do comportamento reológico, térmico e mecânico de misturas de PBAT com elevados teores de lignina
(Universidade Federal de São Carlos, 2019-12-17)
The massive accumulation of plastic waste and its environmental impact is in great evidence today. Each year, more than 8 million tons end up in the oceans, so research indicates that there will be more plastics than fishs ...
Influence of surface treatments on corrosion resistance properties of ultrafine grained titanium alloys for biomedical applications
(Universidade Federal de São Carlos, 2019-08-09)
Titanium and its alloys are used as biomaterials because their excellent combination of high corrosion resistance, low modulus of elasticity and biocompatibility. However, titanium and its alloys cannot meet all the clinical ...
