Introduction

Laser Shock Peening (LSP) is an innovative technology applied to improve the performance of critical components, using pulsed lasers to generate a high-pressure plasma on the surface of the target material. The benefits of LSP typically include deep levels of generated compressive residual stresses with reduced surface integrity modifications, combined with a high degree of process control.

 

Objectives

The South African LSP initiative, originating from a proficient cooperation established between the National Aerospace Centre (NAC), the University of the Witwatersrand (Wits), the Council for Scientific and Industrial Research (CSIR), and AIRBUS Operations GmbH, aimed at developing a local capability to boost the advanced laser-based manufacturing sector.
