Abstract The behaviors of strain electrode of A3 steel in different solutions were studied.The effects of loading on the corrosive rate of A3 steel in different solutions were investigated.The results showed that the applied load did not affect the corrosion rate of diffusion course but accelerated the corrosion rate of activation course and mix course.The surfaces after tests were observed using scanning electron microscope(SEM).This study concluded that for the corrosion system with serious localized corrosion the applied load should be controlled to avoid the crack initiated by the significant stress concentra tion.

Key words: corrosion mechanochemical effect anode polarization stress centralization crack
