A large number of industrial plants and facilities of Japan is often constructed on the seaside area, and so steel materials of these plants and facilities are mostly located under the corrosive environment by sea-salt fine particles. These steel materials are, of course, protected by means of paints, platings or other galvanic protection methods, but some problems to investigate seem still to remain for gaining the better corrosion prevention in such a corrosive environment. In this paper, the results of outdoor atmospheric exposure test by using the small painted specimens are described. The exposure test was practised on the seashore at Tokai Research Establishment of Japan Atomic Energy Research Institute for fourteen months.<br>In this test, it was proved that blasting and control of film thickness could somewhat improve the grade of rust prevention of the exposed specimens, but that melamine-alkyd resin painting systems (total film thickness; 12-36μm) were generally insufficient for a long time rust prevention system in the presence of sea-salt fine particles. On the other hand, the specimens using zinc rich paint primer or hot dip galvanizing as undercoatings (total film thickness; 173-495μm) showed the perfect corrosion resistant properties against the corrosive environment of the test site under the influence of sea-salt fine particles. Moreover, even the specimens of the paint films which were artificially scratched in the shape of cross cut got hardly rust on the bare steel area and no deterioration was found on the paint films.
