Laser shock peening (LSP) is a technique that makes metal parts stronger by creating compressive stresses on their surface. Recent advancements have led to new uses for LSP in areas like 3D printing and ceramics. Different methods like warm LSP and laser peen forming have been developed to improve the process. LSP works by using high-energy lasers to create shockwaves that strengthen the metal. This process also helps prevent cracks and makes the metal grains smaller, improving its strength. Overall, LSP is becoming more versatile and effective in making metal components last longer and perform better.
