Abstract: In this study, in order to further understand the mechanisms of abrasive wear causing significant wear and abrasion, we conducted simple field experiments focusing on the adhesion of sand particles to the sea ice surface or their inclusion within the sea ice, which is the primary cause of abrasion. Also, sliding wear tests were performed under combined conditions of corrosion and other factors. One of the processes by which sand is captured into ice involves sand particles being heated by solar radiation on the ice surface, gradually penetrating, as well as being captured due to freezing/thawing cycles of the ice surface, snowfall, and sea spray. The wear test indicated that the steady abrasive wear rate, defined as the wear amount per unit length, increased linearly with a decrease in ice temperature and sliding speed. Moreover, it was presumed that the steady wear rate, occurring simultaneously due to both corrosive and abrasive wear, would exceed the sum of each corrosive and abrasive wear simply, indicating a synergistic effect.
