Notes:
In the present work, corrosion characteristics of ceramic dispersion strengthened (CDS)high-Cr stainless steel (SS) has been investigated. For the preparation of CDS SS with uniformlydistributed reinforcements, TiC particles were mechanically activated with Cu powder by usinghigh-energy ball mill machine, and then Cu-coated TiC particles were mixed with molten SS.Potentiodynamic polarization curves were experimentally measured on unmodified SS and CDS SSin 0.05 M NaCl solution. The values of corrosion potential Ecorr, corrosion current io, pittingpotential Epit and polarization resistance Rp were quantitatively determined from the measuredpotentiodynamic polarization curves. From the result, it is concluded that CDS SS exhibits highercorrosion resistivity than unmodified SS
