Surface texture with micro pit was processed on the surface of beryllium bronze based on self-built femtosecond laser platform,and the influence law of laser power and pulse number on texture diameter and depth was studied.The unit tribological experiments of rock bit journal bearing were carried out by using pin-disc friction pair of MMW-1computer controlled tribometer to study the effect of surface texture on friction and wear of journal bearing.The results show that with the increase of laser power,texture diameter gradually increases and texture depth gradually decreases.The laser pulse number has no obvious effect on texture diameter,but texture depth gradually increases with the increase of laser pulse number.In addition,the reasonable diameter of texture can effectively reduce surface friction and wear of rock bit journal bearing,and with the increase of texture diameter,friction coefficient and wear volume decreases first and then increases.
