Abstract

In this study the applicability of titanium to sea water has been corrosion fatigue tested. The test specimens were unalloyed titanium welds welded with pure or air contaminated argon. The latter simulates the situation, in which the shielding is not effective enough. The crack growth rates in sea water were compared with the crack growth rates in air atmosphere. Unalloyed titanium weld material as well as air contaminated weld material showed higher crack growth rates in sea water than in air. The difference was more pronounced in the air contaminated weld material. The possible effect of the sea water environment on the fatigue crack growth rates should be considered in the design and fabrication of titanium components. A special arrangement for measuring the crack opening of the specimen tested in sea water was developed for corrosion fatigue tests.
