Influência da adição de Co e Ni e da taxa de resfriamento na microestrutura de solidificação, nas propriedades mecânicas e na corrosão de ligas Al-Si-Cu-Zn-Fe
(Universidade Federal de São Carlos, 2022-11-28)
An important strategy by 2050 will be to transform the production of recycled Al-Si alloys as a viable and sustainable source to reach the global demand for Al. The challenge will be to mitigate the deleterious effects ...
Análises térmica e energética no pré-aquecimento do revestimento refratário de panelas de aciaria via métodos numéricos e experimentais
(Universidade Federal de São Carlos, 2022-04-28)
Preheating the refractory lining of industrial equipment usually consumes substantial amounts of energy. This step is usually time consuming and impacts the costs and productivity of several economic sectors. Therefore, ...
Desenvolvimento, caracterização e desempenho de novos eletrodos para dispositivos eletromecânicos baseados em nanocompósitos elastoméricos condutores tratados por plasma
(Universidade Federal de São Carlos, 2022-06-28)
Ionomeric polymer-metal composites (IPMC) are devices generally composed of metallic electrodes and an ionomeric polymer membrane in a “sandwich-like” format, whose main property is the electromechanical actuation or sensing ...
Recobrimentos de ligas Ti-Nb-Zr depositados por pulverização magneto-catódica sobre aço inoxidável AISI 316L para aplicações biomédicas
(Universidade Federal de São Carlos, 2022-11-30)
The work consists of the deposition of Ti-Nb-Zr ternary alloy coatings in the form of thin films on an AISI 316L stainless steel substrate for applications in the biomedical area, such as dental or orthopedic prosthesis. ...
Atomização a gás do aço ferramenta A2: efeito dos parâmetros de processo nas características do pó
(Universidade Federal de São Carlos, 2022-03-23)
Gas atomization is the main method in powder metallurgy to produce powders for additive manufacturing (AM). The gas atomization process allows generally spherical and very fine metallic powders with great yield on the ...
Desenvolvimento e caracterização de biocompósitos de blendas TPU/PCL com hidroxiapatita para produção de scaffolds bioativos via impressão 3D
(Universidade Federal de São Carlos, 2022-08-02)
The increasing need for biological tissues to treat defects caused by disease or injury has demanded new solutions to provide functional substitutes that supply tissue shortages and suit the needs of each patient. In this ...
Reciclagem de embalagens flexíveis multicamadas
(Universidade Federal de São Carlos, 2022-04-29)
Packaging industry is facing an important paradox in flexible plastic packaging for fresh food. While, food waste is avoided using multilayer and multi-material structures with barrier properties, that increase shelf life ...
Juntas de aço inoxidável super duplex UNS S32760 soldadas por fricção e mistura mecânica (FSW): microestrutura e comportamento de corrosão eletroquímica
(Universidade Federal de São Carlos, 2022-04-29)
In this study, the corrosion resistance of the face and root surface of an AISD UNS S32760 friction stir welded (FSW) joint using optimized parameters was investigated. Microstructural changes were evaluated by MO, SEM and ...
