采用光刻腐蚀技术在钢样品上制备了织构表面。采用表面接触滑动法研究了织构表面的摩擦磨损性能。研究了微坑直径和密度对微坑形貌的影响。结果表明，适当直径和密度的织构表面具有良好的减摩抗磨性能。大直径的凹坑会破坏润滑膜的完整性，而低密度或高密度的凹坑由于摩擦反应在摩擦表面产生更多的硫酸铁和更少的硫化亚铁，从而导致更高的摩擦系数。微凹的摩擦化学膜、微油池和含磨屑的作用共同帮助织构化表面提供改善的抗磨性能。
A photolithography etching technique was used to fabricate textured surfaces on steel samples. The friction and wear behavior of the textured surfaces were studied with surface contact sliding. The influence of the diameter and the density of the dimples were investigated. The results show that the textured surfaces with appropriate diameters and densities had excellent friction reducing and antiwear properties. Large-diameter dimples can destroy the integrity of the lubricating film, and low- or high-density dimples produce more iron sulfates and fewer ferrous sulfides on the rubbing surfaces due to the tribo-reactions, which resulted in higher friction coefficients. The tribo-chemical films, oil micro-reservoir and wear debris-containing roles of the dimples together help the textured surfaces to provide improved antiwear properties.
