In order to improve the lubricating performance of the headface sliding bearing, a new kind of the bionic headface sliding bearing, which has defined lubricating dimple pattern, has been designed based on the phyllotactic theory, and fabricated with UV lithography method and electrolytic technology. A electrolytic experiment of the dimple has been done and analyzed about the influence of the electrolytic time to the electrolytic depth against the different phyllotactic parameters. The analytical results indicate that the phyllotactic parameters influence the lubricating dimple arrangement configuration, so as to improve lubricating performance of the bearing. The increasing diameter of the dimple and the decreasing phyllotactic parameter c can increase the density of the lubricating dimple. Electrolytic experimental results show that the reasonable electrolytic fabricating can reduce the faults of defined lubricating dimple arrangement on the bearing surface.
