Abstract

See full text

In an embodiment, a method of hardening a surface of a substrate comprises directing a waterjet having a transition flow region, the waterjet comprising water and particles, at a surface of a substrate such that the waterjet impacts the surface within the transition flow region to provide a layer of embedded particles underneath the surface of the substrate, thereby forming a hardened substrate. The hardened substrates are also provided.
