摘要

Laser peening is a process in which a laser beam, is pulsed upon a metallic surface, producing a planar shockwave that travels through the workpiece and plastically deforms a layer of material. The depth of plastic de-formation and resulting compressive residual stress are significantly deeper than, possible with most other surface treatments. This article describes some recent developments and applications of laser peening. First we summarize the history and process of laser peening. We then present test results from recent development efforts focused on new applications, describe recently commissioned commercial facilities, and discuss some production-related advances.
