1. Anticorrosive Effect of PVP 40000 Against AISI 1020 Carbon Steel in HCl
Polymers have received considerable attention for replacing synthetic inorganic and organic anti-corrosion inhibitors since they are not as toxic for the environment, besides being cheaper. Polyvinylpyrrolidone (PVP) has been studied due to its applicability, solubility, very low toxicity, cost and efficiency in corrosion inhibition against metals, such as z

2. Estudo da corrosão localizada da liga de alumínio 7475-T761 por espectroscopia de impedância eletroquímica global e local em meio de sulfato de sódio. / Localized corrosion study of aluminum alloy 7475-T761 in sulfate medium using global and local electrochemical impedance spectroscopy.
Aluminum alloys used in the aerospace industry with structural purpose exhibit a complex microstructure due to thermal and mechanical treatments they are submitted for improving their strength. The microstructure of these alloys is characterized by the presence of a great number of intermetallic (IM) particles, the electrochemical activity of which is differ

3. SÍNTESE DE (TIO)SEMICARBAZONAS E AVALIAÇÃO EXPERIMENTAL E TEÓRICA DA ATIVIDADE ANTI-CORROSÃO / SYNTHESIS OF (thiosemicarbazones AND EVALUATION AND EXPERIMENTAL THEORY OF ACTIVITY ANTI-CORROSION
Nesta Dissertação foram sintetizados 30 compostos, sendo 15 pertencentes à classe das semicarbazonas e os outros 15 pertencentes à classe das tiossemicarbazonas, com o objetivo de avaliar a eficiência dos mesmos como inibidores de corrosão. Os compostos foram previamente analisados por Modelagem Molecular, obtendo-se informações a respeito de proprie

4. Novas formulações de fluidos de corte: otimização, propriedades e recuperação do óleo usado
Cutting fluids are lubricants used in metal-mechanical industries. Their complex composition varies according to the type of operation carried out, also depending on the metals under treatment or investigation. Due to the high amount of mineral oil produced in Northeastern Brazil, we have detected the need to better use this class of material. In this work,
