Description
The fatigue crack growth behavior of welded ABS DH32 steel spec~mens
cathodically polarized to -1.00 volt (Cu-CuS04) and subjected to bending
fatigue of nominal stress + 69 MN/m^2 (+- 10 ksi) in seawater was
investigated. Small non-propagating surface cracks with lengths up to
4.93 mm formed in the specimens. There were no s~gns of failure after
36 x 10^6 cycles when the experiment was terminated. Comparison of
this test with similar freely corroding and -0.85 volt (Cu-CuS04)
tests indicated that -1.00 volt (Cu-CuS04) cathodic protection is conducive
to arrestment of small fatigue cracks. This suggests that
modest cathodic over-protection of steel in seawater may beneficial.
