Resumo: The purpose of this study was to evaluate the corrosion behavior of 1010 steel processed by Equal Channel Angular Pressing (ECAP), a technique that induces severe plastic deformation (SPD) in materials. The samples were processed by one and two passes of ECAP throught routes A and C. The corrosion behavior was evaluate using the potentiodynamic polarization and electrochemical impedance spectroscopy, using NaCl (pH= 6.5) and sodium hydroxide/sodium phosphate (pH= 10.5) solutions. The polarization tests showed better performance for the samples processed by ECAP than in the as cast samples both in alkaline and neutral solutions. The results showed that alkaline solution presented higher corrosion rate for the as cast and one ECAP pass materials. It is seen that samples processed throught routes A and C develop a film stabilization on the surface of these samples. In addition, the values of polarization resistance obtained from the electrochemical impedance spectroscopy in NaCl environment were higher for sample processed in route C.

As amostras foram processadas em um e dois passes nas rotas A e C. O comportamento em relação à corrosão foi estudado por meio da polarização potenciodinâmica e espectroscopia de impedância eletroquímica em soluções de NaCl (pH = 6,5) e hidróxido de sódio/fosfato de sódio (pH = 10,5). Os testes de polarização apresentaram melhores desempenhos para as amostras processadas por ECAP do que nas amostras sem processamento, e isso ocorreu tanto na solução alcalina quanto na neutra. Os resultados mostram que os materiais no estado bruto de fusão e em apenas um passe de ECAP apresentaram maior taxa de corrosão em solução alcalina. Foi observado que as amostras processadas nas rotas A e C promoveram uma estabilização do filme em suas respectivas superfícies. Ademais, os valores de resistência de polarização obtidos por espectroscopia de impedância eletroquímica em ambiente de NaCl foram maiores para a amostra processada na rota C.2022-10-06T19:53:36Z2022-10-06T19:53:36Z2021info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfBRAGA, J. de O. et al.
