摘要

Fatigue crack growth rate (FCGR) tests were conducted on Titanium Alloy Ti-5111 weld metal in air, artificial seawater, and artificial seawater with an applied cathodic potential. The results indicated a minor effect of seawater in increasing FCGR of Ti-5111 weld metal. However, the application of a cathodic potential of 0.987 V versus Ag/AgCl reference electrode showed crack growth rates similar to FCGR in air. Additionally, comparisons are made regarding the FCGR behavior of Ti-5111 plate, Ti-100 (Ti-621-0.8Mo) plate, and Ti-5111 weld metal in both air and seawater. These results indicated that both high strength titanium alloy grades, including the base and weld metal, performed similarly in all test environments.
