Mesoscopic tribological control in microforming by tailored surface texturing

为了通过设计复杂接触条件下的微成形模具表面织构来实现微成形摩擦学性能的优化，本研究旨在阐明微成形中特定接触条件下微观表面织构尺寸与摩擦磨损性能之间的关系。通过研究发现，在干滑动摩擦条件下，表面毛化的主要贡献是增强了磨粒的喷射。基于这一结果，可以根据微成形过程中接触长度和表面压力的变化来设计其间隙和宽度的表面毛化尺寸。

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.
