| Abstract: |
| The free corrosion potential（Ecorr）of high-strength steel in 3.5% NaCl solution was monitored during corrosion fatigue crack propagation process, and the relationship between corrosion fatigue crack propagation rate(CFCPR) and Ecorr was analyzed. The relationship formula between CFCPR and the changed values of Ecorr（ΔE） of high-strength steel was established. The CFCPR was linearly with ΔE. |
