Friction performance effect of marine coating on ice abrasion

Abstract

This study describes a new assessment technique for evaluating marine coating performance on ice. The current evaluation methods related to the ice friction performance are investigated and their limitations are analyzed. To ensure the accuracy and validity of the study, ice abrasion specimens were prepared using paints applied to actual ice-class vessels. Instead of the commonly used rubber material roller, the cold model ice was used as the corresponding abrasion materials on the coating. To assess ice friction and abrasion performance, a new test procedures are developed. Abrasion was generated in the unit of abrasion distance of about 3 km per coating, and abrasion was finally generated up to about 12 km. As the ice abrasion progressed, scratches and peelings occurred on the surface of the IPC, therefore, it was found that the surface roughness and frictional coefficient of the IPC gradually increased. AFC, on the other hand, tended to separate like dust as the surface coatings were ground on ice, and the surface roughness but also frictional coefficient did not change significantly. It was confirmed that the ice abrasion phenomena were different according to the type of paints and the ice friction performance effect of the marine coating could be varied.
