【 摘 要 】

This study investigated the effect of surface groove micro-texturing on hydrodynamic lubrication characteristics. All textured samples were processed by laser; non-textured reference samples were also created for comparison. Four types of surface groove patterns with different groove angles and groove depths were utilised. Different rotational speeds and gaps were used in the experiment to explain the relationship between the load-carrying capacity and the groove texture parameters under different conditions. The results suggested that the load-carrying capacity was greatly influenced by the operational conditions and that the samples with surface groove textures generated a larger hydrodynamic lift force than the non-textured samples.
