| Outline of Final Research Achievements |
In the present investigation, the adhesion force between actual sliding metal surfaces was determined by using both friction force microscopy and force-distance curves (FFM-FDC method). Measurement was performed for 50 repetitions of the sliding-adhesion cycle, which consisted of applying sliding friction in FFM mode followed by measurement of adhesion force based on the pull-off force in FDC. The measurement experiments were conducted using nine probe cantilevers made of nine different metals and their corresponding metal blocks. Nanoscale observation and analysis of the sliding surfaces by SEM and AFM revealed the number of wear elements and their generation mechanism. The effects of adhesion force on the mechanism of adhesive wear and the adhesive wear equation are discussed.
