Abstract A nanocrystallized surface was fabricated on low ca rbon steel by using ultrasonic shot peening (USSP) technique.The grain size on t he top layer of surface nanocrystallized (SNC) low carbon steel was about 20 nm, which increased with the distance from the peening surface.The electrochemical c orrosion behaviors of SNC low carbon steels with different grain sizes were stud ied by electrochemical methods in 0.05 mol/L H2SO4+0.05 mol/L Na2SO4 aqu eous solution.There existed a grain size effect on the electrochemical corrosion of SNC low carbon steel when the grain size was lower than 35 nm.The corrosion rates of SNC low carbon steels increased with the decrease of the grain size.The rise of corrosion rate was attributed to the more active atoms on the grain bou ndary caused by SNC.

Key words: grain size effect electrochemical corrosion low carbon steel surface nanocrystallization
