摘要: Corrosion behavior of sintered oxide dispersion strengthened duplex stainless steel composites in pineapple juice extract was investigated using weight loss and potentio-dynamic methods. The scope of the work includes investigations on the effects of alloying elements, grain growth inhibitors, varying reinforceing ceramics starting powders. The sinter oxide dispersion strengthened (ODS) samples were characterized, using a combination of varying analytical techniques; scanning electron microscopy (SEM) and x-ray diffractometer (XRD). Gravimetric method is based on weight loss measurement while potentio-dynamic polarization scanning was done using an autolab potentiostat (PGSTAT 204 computer controlled) using the general purpose electrochemical software (GPES) version 1.10. Potentio-dynamic polarization curves were collected by scanning the potential from-1.0 to+ 1.5 V against Ag/AgCl at a scan …
