Abstract
 Tests involving sea ice friction-related wear/abrasion on various metals such as carbon steel, stainless steel and titanium were carried out to clarify the characteristics of deterioration in steel structures such as sheet piles in ice covered areas. Each metal test piece was placed in contact with artificial saline ice under certain levels of pressure using an oil jack, and reciprocating motion was introduced. Although wear also increased with higher levels of contact pressure, the rate of increase fell at pressure values of around 0.5 MPa or more. Conversely, the wear amounts of stainless steel and titanium were close to zero, despite the minimal difference between the Brinell hardness values of the metals. Accordingly, the main factor influencing this type of deterioration in carbon steel is corrosive wear rather than adhesive wear. Further, because the wear rate per unit time for carbon steel increased linearly with the sliding speed, it can be concluded that ice action promote the corrosion of steel by stimulating its surface.
