摘要: This study presents a systematic investigation of the corrosion behavior and corrosion mechanism of a novel ultralow-carbon Cr–Mo alloyed ferrite/bainite duplex steel rebar. Electrochemical tests revealed the studied steel rebar to have satisfactory corrosion resistance in an NaCl medium, similar to 430 stainless steel and better than 403 stainless steel. The formation of a Cr-dominated bilayer-structured oxidation passive film endows the steel with excellent passivity. During long-term exposure, the Cr–Mo alloyed steel presented …
