Abstract

Fatigue failure is a very common form of fracture failure for metallic materials, which can have harmful effect on the safe service of the material. In recent years, many studies have been carried out to improve the fatigue properties of materials and prolong the service life of metallic components by using different methods. Particularly, laser surface treatment technologies have been widely studied and applied in engineering due to their advantages, which can improve fatigue properties of materials by strengthening the original specimens and healing the specimens with certain damage or microcracks. This paper introduces the research status and reviews the achievements of several laser surface treatment technologies in previous research on material fatigue. In addition, the further research directions of laser surface treatment technologies in material fatigue are proposed.
