Evaluating Methods for Quality of Laser Shock Processing

Abstract Laser shock processing is an advanced surface modification technology that can effectively enhance the mechanical properties of alloy and metallic materials, such as micro-hardness, fatigue resistance and corrosion resistance, by using laser-induced plasma shock waves, and it has a wide applications in the field of aerospace industry. In this work, the development of laser shock processing is introduced briefly, the research of evaluating methods for quality of laser shock processing is summarized emphatically, and the study necessary of online measuring methods for quality of laser shock processing is indicated.
