Study on Laser Surface Microtexture Processing and Friction of 45 Steel

摘要

To study the effects of different surface microtextures on the friction and wear properties, the microtextures were processed on the 45 steel surfaces by pulsed laser. It showed that the textured surfaces with pits and grooves had an effect on the storage of lubricating oil and abrasive particles, which can improve friction and wear behavior of surface. Compared with smooth sample surface, the wear resistance and anti friction of textured surface were significantly improved; the improvement of abrasive resistance of textured surface with appropriate texture area ratio is more remarkable.
