Abstract The corrosion fatigue crack growth (CFCG) of DH36 steel in artificial seawater was studied via a home-made test set, which can accurately control the load, stress ratio, frequency, temperature, flow rate, pH value, ion concentration, and other factors of the artificial seawater, meanwhile, electrochemical monitoring of the whole process could be applied. The results show that the higher the stress ratio R, the faster the CFCG rate. The average acceleration ratio of CFCG rate by R=0.3 and R=0.5 is 115% and 217% of that by R=0.1 respectively. On the other hand, the CFCG rate becomes faster with the increase of temperature. The average acceleration ratio at 30 ℃ is only 20% of that at 5 ℃. The CFCG rate turns to be faster with the increase of seawater flow rate. The average acceleration ratio by flow rate of 0.3, 1 and 3 L/min, is 19%, 34% and 50% of that in static seawater, respectively. There is no difference in the fatigue crack growth (FCG) rate in air by changing test frequencies, but there is a great difference in the CFCG rate in seawater, namely the lower the frequency, the faster the CFCG rate. By comparing the CFCG rate with the FCG rate by different frequencies, it shows that seawater corrosion can inhibit the crack growth to certain extent at 10 Hz, but accelerates the crack growth at 1 and 0.1 Hz with an average acceleration ratio of 47.8% and 261.8%. The acceleration effect of corrosion on fatigue crack growth can be quantified by in-situ monitoring the electrochemical corrosion behavior at the crack tip during CFCG.
