The relationship between attaching organisms and corrosion of different metals was studied using six metal test plates exposed in 3 meters depth in Suruga Bay off Nishiura-Kisyo, Numazu, Shizuoka, in coastal Japan. The extent of corrosion of mild steel depended on the attachment of barnacles and, in addition, there was virtually no attachment to rust surfaces. There was hardly any difference between the corrosion rates of zinc and 90Zn-10Al alloy and the corroded surfaces were smoother than those of mild steel. Furthermore, although Botrylloides and diatoms readily became attached, barnacles did not; the few barnacles that did settle on these plates readily detached along with the zinc hydroxides that are the corrosion products. There was no great difference in the corrosion rates of pure copper and 90Cu-10Ni alloy, although pitting was observed on the pure copper plate. Slime, including diatoms, was observed on both metals, but there was no attachment of macroorganisms. Meanwhile, in the case of stainless steel, surfaces without any attached organisms showed virtually no corrosion, but crevice corrosion was observed here and there at barnacles attachment sites.
