Abstract

See full text

Described herein are systems and methods for performing a surface mechanical attrition treatment (SMAT) to the surface of a variety of materials including thin films, nanomaterials, and other delicate and brittle materials. In an aspect, a surface of a material is modified to a modified surface and from an original state to a modified state, wherein the modified state comprises a physical modification, a chemical modification, or a biological modification. In another aspect, a surface mechanical attrition treatment (SMAT) is applied to the modified surface of the material for a defined duration of time, wherein a condition associated with the SMAT is adjusted based on a structural composition of the material. In yet another aspect, a defined strain is imposed on the structural composition of the material based on the SMAT.
