The article discusses experimental studies assessing the possibility of mapping surfaces with a characteristic distribution of irregularities. Tests involved surfaces produced using the L-PBF additive technology, using titanium-powder-based material (Ti6Al4V). An evaluation of the resulting surface texture was extended to cover the application of a modern, multiscale analysis, i.e., wavelet transformation. The conducted analysis that involved using selected mother wavelet enabled production process errors and involved determining the size of resulting surface irregularities. The tests provide guidelines and enable a better understanding of the possibility of producing fully functional elements on surfaces, where morphological surface features are distributed in a characteristic way. Conducted statistical studies showed the advantages and disadvantages of the applied solution.
本文讨论了评估绘制具有不规则特征分布表面可能性的实验研究。测试涉及使用基于钛粉材料（Ti6Al4V）的激光粉末床熔融（L-PBF）增材制造技术生产的表面。对所得表面纹理的评估扩展到涵盖现代多尺度分析的应用，即小波变换。所进行的分析涉及使用选定的母小波，能够检测生产过程中的误差，并确定所得表面不规则性的尺寸。这些测试提供了指导方针，并有助于更好地理解在形态表面特征以特征方式分布的表面上生产全功能元件的可能性。所进行的统计研究显示了所应用解决方案的优缺点。
