The concepts and properties of nanoskin materials and components created by ultrasonic nanocrystal surface modification

摘要：

　　Material surface and immediate subsurface layers can be called skin.A novel Ultrasonic Nanocrystal Surface Modification (UNSM) technology produces uniformed micro dimples on the top surface and nanometer grain in the subsurface,increases surface hardness and induces compressive residual stress.This way mechanical characteristics related to fatigue,wear,friction,etc.can be improved.The concepts and properties of nanoskin materials and components are proposed with their potential application.
