Abstract
Sea ice always moves in the up-and-down direction under the influence of a tide. If the conditions, that could remove rust layers, are as usual in the field, larger wear of steel in ice-infested sea compared to ice-free sea must be considered in the design of steel structures. The sliding wear test in a low-temperature chamber was carried out to examine the conditions of removing rust layers, using corroded steel specimen with rust layers in contact with saline ice. The contact pressure, grain size and amount of sand at the interface were taken as paramaters here to understand corrosive wear in the ice-infested sea. This research leads to the prediction of the deterioration of steel in ice-infested sea, using the obtained results and environmental conditions in-situ, and the relation of elapsed year to corrosion amount.
