激光冲击强化技术的研究与应用

Study and Application on Laser Shock Processing Technique

本文介绍了激光冲击强化技术这种新型的金属材料表面强化技术，该技术可大幅度提高金属材料的疲劳寿命，为提高传统材料的综合力学性能和服役行为开辟了新路；文章重点论述了该技术在美国的工程应用情况以及国内的研究进展，最后简述了我国首条激光冲击强化生产线相关情况。

The article introduces a new type technique-laser shock processing （LSP） technique, which is a new metal surface strengthening treatment technique. We can use the LSP technique to improve the fatigue life of metal material, and it offers a new method to improve the comprehensive mechanics property and service behavior of traditional material. The article focuses on the engineering application of this technique in the USA and the researching progress in China. At last the article gives a brief introduction of the first LSP production line in our country.
