Resumo
Neste trabalho, tubos de aço inoxidável supermartensítico (AISM) foram soldados por fricção radial (SFR) e suas propriedades de corrosão foram estudadas através de ensaios de polarização anódica em solução de 3,5 % de NaCl e da técnica eletroquímica de reativação potenciocinética de ciclo duplo (DL-EPR

Abstract: In this work, supermartensitic stainless steel pipes were radial friction (RF) welded and their corrosion behavior were studied based on potentiodynamic polarization and double loop -electrochemical potentiokinetic reactivation (DL-EPR) tests. Measurements were performed on samples taken from the base metal (BM), weld interface, and consumable ring (CR
