Abstract

Disclosed are a strengthening device and method for improving fatigue, wear and corrosion performance of metals. In the present disclosure, a femtosecond laser device, an optical transmission module, an optical platform, a five-axis mobile platform, a femtosecond laser processing head, and a central processing unit are included, where laser scanning processing is completed by means of the synergy of the five-axis mobile platform and a scanning galvanometer. A femtosecond laser processing process method for regulating and controlling shock wave pressure and surface self-organizing structure characteristics is proposed by the present disclosure, where a work-hardening layer and a wear-resistant and hydrophobic micro-nano structure are prepared on a surface of the metal in one step by means of the femtosecond laser, and simultaneous improvement of the fatigue, wear and corrosion performance of the metals is achieved.
