The work aims to further improve tribological properties and carrying capacity of micro-textured surface, and study the law of effects of different dimples combined distribution on surface properties. Finite element simulation technology and single factor design were used to analyze and compare effects of micro-textured surface textured with all hemispheric dimples, square dimples and triangle dimples on tribological properties of Inconel 718 alloy. Law of the effects of different micro-textured surfaces on bearing capacity and friction coefficient of oil film was analyzed and obtained. The micro-textured surface textured with all three dimple shapes exhibited the best bearing capacity. And the micro-textured surface with hemispheric dimples and square dimples had the minimum friction coefficient. For the Inconel 718 high-temperature alloy surface textured with modified dimples, the bearing capacity of oil film can be improved significantly, which is beneficial to the formation of complete oil film. Combined distribution of different dimple shapes has great significance on tribological properties and bearing capacity of material. Moreover, the gap among friction coefficients of different micro-textured surfaces narrows as the velocity and load increase, which implies that dimple shapes and combined distribution have weaker effects on tribological properties.
