Micro-dimpled surface by ultrasonic nanocrystal surface modification and its tribological effects

► EBSD micrographs show that more surface plastic deformation is observed in the surface layer of the UNSM-treated surface comparing to the untreated surface. ► The key point for realizing the surface nanocrystallization of a bulk material is to introduce interfaces into the surface layers, so that...
