The study of laser shock peening with side-water spraying and coaxial-water feeding technology

The study presents laser shock peening with side-water spraying and coaxial-water feeding technology. Results show that laser shock peening improve the hardness and mechanical property of the 5083Al material through side-water spraying. The protective layer could minimize the ablative damage of laser on the surface of the 2024Al specimen. The laser shock peening technology with coaxial-water feeding was used to treat 5083Al, and it could be obtained that the new laser shock peening method has obviously beneficial results in practical application.
