Comparison of the corrosion of ferritic and austenitic stainless steel (AISI 43...
Gil, Mafalda; Pedrosa, Fátima; Paiva Luís, Teresa; Figueira Vasques, Isabel; Oliveira, Fernando; Cunha Diamantino, TeresaABSTRACT: This study focuses on the corrosion rates and mechanisms of two stainless steels, austenitic AISI 316L and ferritic AISI 430, in contact with a eutectic mixture of LiNaK carbonates in long-term tests at 650 degrees C. The selection of these two stainless steels was based on their differences, both in their intrinsic characteristics and in the cost associated with each one. The research also underscore...
Li-ion Battery Recycling: A Summary Review
Nogueira, Carlos; Neiva Correia, Maria Joana; Margarido, Fernanda; Plancha, Maria João; Pedrosa, Fátima; Gonçalves, Ana; Silva, Clara; Silva, SaraABSTRACT: A short review of battery recycling technologies is presented. Main components and materials of battery cells, modules and packs are identified, highlighting their compositions and contents. Main component of packs is aluminium, followed by the cathode materials, anode materials, copper and polymers. Safe discharge of the spent batteries is mandatory, and the subsequent dismantling allows separation a...

Corrosão dos aços AISI 316L e AISI 430 em contacto com sais fundidos de carbona...
Gil, Mafalda; Pedrosa, Fátima; Paiva Luís, Teresa; Figueira Vasques, Isabel; Cunha Diamantino, TeresaRESUMO: Os desafios da transição energética e a tendência crescente da eletrificação da economia implicam uma clara aposta no aumento da utilização de energias renováveis. Nesse sentido, os sistemas de concentração de energia solar (CSP) ganharam considerável relevância na conversão de energia solar térmica em energia elétrica [1]. Com o crescente desenvolvimento e implementação destas tecnologias que utilizam ...
Methodologies for assessing corrosion under dynamic conditions with molten salt...
Cunha Diamantino, Teresa; Pedrosa, Fátima; Paiva Luís, Teresa; Figueira Vasques, Isabel; Gil, Mafalda; Navas, M.; Veca, E.ABSTRACT: Renewable energy implementation represents a key point in reversing global warming and climate change. In recent years, there has been an investment in Concentrated Solar Power (CSP) with Energy Storage (TES). Solar Salt is the most energy storage fluid optimized with a melting point of 223 °C and thermally stable up to about 550 °C. One of the most relevant problems in the use of fluids as thermal en...

Pedrosa, Fátima; Cunha Diamantino, Teresa; Gil, Mafalda; Paiva Luís, Teresa; Figueira Vasques, IsabelRESUMO: Um dos pontos fulcrais na utilização de sais fundidos como fluidos de armazenamento de energia térmica nas tecnologias de concentração de energia solar é a sua compatibilidade com os materiais estruturais metálicos. A corrosão dos materiais metálicos, tanto ao nível dos tanques de armazenamento de energia térmica, como ao nível das tubagens onde circulam estes fluídos, é um dos grandes desafios destas c...
Hot Corrosion Behavior of Slurry Sprayed Aluminide Coatings in a Simulated Dyna...
Audigié, Pauline; Rodríguez Catela, Sergio; Agüero, Alina; Pedrosa, Fátima; Paiva Luís, Teresa; Cunha Diamantino, TeresaABSTRACT: One of the key challenges associated with the use of molten salts in Concentrated Solar Power (CSP) plants is to reduce or even suppress corrosion phenomena occurring at elevated temperatures. Molten nitrate mixtures are currently seen as the most viable storage medium for Thermal Energy Storage. But the upper temperature limit of the currently used “Solar Salt” is restricted by salt decomposition at ...
Comparison of descaling methods to study the corrosion kinetics of ferritic ste...
Audigié, Pauline; Rodríguez Catela, Sergio; Agüero, Alina; Pedrosa, Fátima; Paiva Luís, Teresa; Cunha Diamantino, TeresaABSTRACT: T91 ferritic-martensitic steel was exposed to Li, Na and K molten carbonates at 650??C under dynamic conditions up to 1000 h. After testing, three descaling methods, two from the ISO8407 and one from the ISO17245 stan-dards were applied to remove the corrosion products and determine the corrosion rates. The two ISO8407 methods were more appropriate although the procedure required several steps to full...
