目的 研究不同形貌的微结构表面对金属表面润湿性能的影响。方法 首先在金属材料表面建立一级与二级微结构模型，然后整理得出不同微结构模型评定参数的公式，最后利用Matlab对不同形貌表面相关公式进行模拟计算，绘制得到不同形貌表面润湿特性三维曲线。结果 一级微结构中，球形微结构模型表面表观接触角θ皆为定值，即完全润湿θc=74.443°，不完全润湿θw=131.720°。其余微结构模型利用Matlab模拟计算，均可以得到光滑的三维曲线，其中在铜基表面设计制备三维方柱阵列微结构，可获得超疏水特性。二级微结构中，比较完全润湿状态，不完全润湿状态粗糙因子f远小于Υ。在不完全润湿状态中，粗糙因子f趋近于0，与完全润湿状态模拟的表观接触角结果相比，不完全润湿状态下，采用三维阵列微结构研究金属表面微结构对表观接触角的影响最为合适。结论 模拟条件相同的情况下，改变金属表面微观形貌会引起润湿性能的改变。金属表面润湿性能与表面微细结构以及微结构参数均存在映射关系，但是表面微结构的维度并非越高越好，一级微结构同样也可以得到所需疏水性能。在外在影响因素相同的条件下，若要研究分析金属表面微结构参数的改变对表观接触角的影响，采用三维阵列微结构最为合适。

The work aims to study the effects of microstructure surface with different morphologies on the wettability of metal surface. Firstly, the first-level and second-level microstructure models were established on the surface of metal materials, and then the formulas for evaluating parameters of different structure models were worked out. Finally, the relevant formulas of different morphologies were simulated by Matlab to draw 3D curves of surface wetting characteristics of different morphologies. In first-level microstructure, the apparent contact angle θ on spherical structure was constant, θc=74.443° in complete wetting state and θw=131.720° in incomplete wetting state. For remaining microstructure models, smooth three-dimensional curves could be obtained by Matlab simulation. The three-dimensional square-column array microstructure could be designed and fabricated on the copper-based surface to obtain super-hydrophobic characteristics. In secondary microstructure, compared with relatively complete wetting state, incomplete wetting roughness factor f was far less than Υ completely. The roughness factor f was almost close to zero in the incomplete wetting state. Compared with the apparent contact angle results simulated by the complete wetting state, the three-dimensional array microstructure was most suitable for studying the effect of the metal surface microstructure on the apparent contact angle. Changing the microscopic morphology of the metal surface causes a change in the wetting property under the same simulation conditions. The wetting property of the metal surface has a mapping relationship with the surface microstructure and microstructure parameters, but the dimension of the surface microstructure is not as high as possible, and the first-level microstructure can also obtain the desired hydrophobic properties. When the external factors are the same, if the influence of the change of the microstructure parameters on the surface of the metal on the apparent contact angle is required to be studied, the effect of the three-dimensional array microstructure is the most suitable.
