Weldments representative of a range of marine structural materials were exposed to a natural marine environment, which was known from previous studies to induce microbially influenced corrosion (MIC). The natural environment was at a University of Delaware site on the Delaware Bay, Lewes, Delaware. Companion laboratory control tests were conducted at the University of Tennessee in 0.2 {micro}m filtered Delaware Bay water and in synthetic seawater. The natural and control tests were conducted with weldments in both creviced and noncreviced conditions. Open-circuit potentials (OCPs) and corrosion rates (polarization-resistance measurements and microscopic examinations) were evaluated for all tests. The weldments studied were: UNS S30403 (304L), UNS S31603 (316L), and UNS N08367 (AL-6XN) stainless steels; HY-80 and K 11576 (HSLA-80) low-alloy steels; alloy 400 M-Cu alloy; 90-10 Cu-Ni alloy; 5086 aluminum alloy; and unalloyed titanium.
