Fig.6(a)shows potentiodynamic polarization curves of the BM,NFSP,and SFSP samples.Corrosion potentials(Ecorr),corrosion current densities(icorr),and corrosion rates(v,calculated by Eq. (1)) are summarized in Table 2.Values of Ecorr,icorr,and v of the NFSP and SFSP samples are both lower than those of the BM sample,and values of Ecorr,icorr,and v of the SFSP sample are lower than those of the NFSP sample.The decrease of corrosion potential indicates that FSP-prepared low-carbon steel is more susceptible to corrosion and can more easily form a passive film.The density of the passive film directly affects the corrosion rate.
