Research Abstract

This study examines the temperature dependence on corrosion technique for corrosion-resistant material using radiation induced surface activation(RISA) in artificial and natural seawater. The experimental results revealed : 1) The RISA effect appeared obviously when the temperature was under 30℃and diminished when over 45℃. 2) The effect occurred in all seasons, decreased with the temperature increased. 3) The mechanism behind the corrosion control proposed by the previous report was confirmed to be appropriate. This via tests that measured the amount of dissolved oxygen in natural seawater. The corrosion control technique for corrosion-resistant material using RISA in seawater has therefore been shown to offer a significant potential for practical applications in naval architecture and marine structures.
