Abstract
Surface texturing has been considered as an effective approach to improve the tribological performances. Based on the consideration of enhancing the tribological performance, the experiments are carried out to investigate tribological performance of triangular textures in water lubrication. The textures are generated by the Nd:YAG laser marking system, with an area density of 20% and a depth of 7 μm and are distributed uniformly on the surface of the SiC rings. Compared with the circular textures, the triangular textures have obvious tribological anisotropy. The triangular textures in clockwise direction show the best friction reduction effect among the three textures. The friction reduction mechanisms of the triangular textures in clockwise direction are also analyzed and discussed.
