Abstract

See full text

Provided is a combined fabricating method for gradient nanostructure in the surface layer of a metal workpiece. A plastic deformation layer in great depth is induced by laser shock peening, then the surface of the metal workpiece is nanocrystallized by surface mechanical attrition treatment, and finally a gradient nanostructure is obtained in the surface layer of the metal workpiece with desirable layer thickness and optimized micro-structure distribution.
