英文摘要：

In order to improve the surface quality of laser processing texture,apicosecond laser processing system is structured.The effects of laser processing parameters on the surface texture profile are investigated.Testing results show that the structured picose-cond laser system can process pretty good surface texture.Using the picosecond laser processing system,the end surface of the ring sample is textured with circular dimples.Sliding line-contact tests indicate that surface texture can decrease the friction coefficient,extend the friction life,and avoid severe wear occurrence.
