Effect of Cylindrical Micro-Pit’s Distribution Form on Tribology Properties of Textured Surface

Tribology properties of textured surface with cylindrical micro-pits was studied by numerical method, and effect of geometric parameters of micro-pits and relative velocity between two reciprocating parallel surface on friction and bearing capacity were analyzed. The results show that the bearing capacity of textured surface increased 34.9 times with the increase of offset ratio of position from 0 to 0.5, and the friction between two surfaces increased slightly with the increasing of offset ratio. Increasing the radius of micro-pits can improve the bearing capacity and reduce the friction simultaneously. The friction and bearing capacity first increased and then decreased with the depth of texture increasing from 10 μm to 60 μm, and both the friction and bearing capacity reached maximal value when the depth of texture was 20 μm.
