The objective of this work is to investigate the relationship between wettability and surface microgeometry of 6060 aluminum alloy created by electric discharge machining (EDM). The analyzes are enriched with the calculation of the correlation strengths between contact angles and geometric characteristics of surface topographies changing with the scale of observations. Surface topographies are measured by focus variation microscope and characterized with ISO parameters, geometric motifs and multiscale curvature tensor analysis. The wettability of the finished structures is investigated indirectly by contact angle measurements. The analysis were carried out using aqueous solutions of the semi-synthetic polymer, with different concentration and viscosity. The study showed that wetting behavior of aluminum alloy can be easily controlled through appropriate EDM finishing.

这项工作的目的是研究通过电火花加工 (EDM) 产生的 6060 铝合金的润湿性和表面微观几何形状之间的关系。通过计算接触角和表面形貌的几何特征之间的相关强度，丰富了分析，这些特征随着观察的规模而变化。表面形貌通过焦点变化显微镜测量，并用 ISO 参数、几何图案和多尺度曲率张量分析表征。通过接触角测量间接研究成品结构的润湿性。使用具有不同浓度和粘度的半合成聚合物的水溶液进行分析。
