To realize the optimization of tribological properties in microforming by designing the surface texture on microforming die, which is under the complex contact conditions, the present study aims to clarify the relevance between the dimensions of micro surface texture and friction and wear properties under the specific contact condition in microforming. Through the investigation, it was found that the main contribution of the surface texturing under dry sliding friction were the enhancement of the wear debris ejection. Based on this result, it was demonstrated that the surface texturing dimensions of its gaps and width could be designed corresponding to the variation of contact length and surface pressure during the microforming process.

为了通过设计复杂接触条件下微成形模具的表面织构实现微成形摩擦学性能的优化，研究了微成形特定接触条件下微成形模具表面织构尺寸与摩擦磨损性能的相关性.通过研究发现，干摩擦条件下表面织构化的主要作用是促进磨粒的排出。在此基础上，根据微成形过程中接触长度和表面压力的变化，可以设计微成形间隙和宽度的表面织构尺寸。
