The complex surface topography of a scraped surface is studied quantitatively. The scraped surfaces are composed of the surface elements which are formed by each scraping operation, distribute in the depth direction, and have many asperities. Based on this model, the microscopic contacting problem between two scraped surfaces and static frictional characteristics are investigated under boundary lubrication. As a result, it is clarified that the ellipsoidal shape of the asperity tip of scraping surface may be regarded as optimal from the point of static friction, and the static friction characteristics are considerably influenced by the scraping directions.
