添加加工(AM)金属的表面表征只有在它们能够可靠地与性能特性相关并且与其他表面(包括AM和传统加工表面)进行比较的情况下才有价值。在这项工作中，我们的目标是为具有代表性的金属AM零件的精确、可比较的表面粗糙度测量定义最佳实践。这些参数广泛地依赖于：1)仪器、2)采集参数和3)分析方法。AM表面独特的粗糙度范围很大，从印刷时非常粗糙的绒毛(粉状AM为25微米)，到抛光后的镜面(<；1微米)，需要不同的考虑。这项工作概述了测量激光粉床熔化AM 316和L不锈钢样品表面粗糙度的决策过程，详细说明了所需的样本量以及采集参数，如z范围。使用相干扫描干涉法、激光扫描共聚焦显微镜、结构白光三角测量法和物理轮廓术对四种仪器的结果进行了比较。通过不同测量技术的比较，证明了所建议的参数空间的广泛适用性。将提供使用不同仪器获取的合格测量的建议，这些建议未在本工作中进行探讨。这将允许对基于区域的表面地形测量进行社区范围的比较，超出国际标准化组织21920-3-2021年建议的线性测量标准。
Characterization of surfaces for additively manufactured (AM) metals are only valuable to the extent that they can be reliably related to performance properties and compared to other surfaces, including both AM and traditional manufactured surfaces. In this work we aim to define best practices for precise, comparable surface roughness measurements of representative metal AM parts. These parameters are broadly dependent on: 1) instrument, 2) acquisition parameters, and 3) analysis methods. AM surfaces uniquely span a large range in roughness, from extremely rough as-printed down skins (>25 µm for powder based AM), to mirror-like surfaces after polishing (<1 µm), requiring different considerations. This work outlines the decision process for measuring surface roughness of laser powder-bed fusion AM 316 L stainless steel samples, detailing the required sample size as well as acquisition parameters, such as the z-range. The results are compared across four instruments using coherent scanning interferometry, laser scanning confocal microscopy, structured white light triangulation, and physical profilometry. Comparisons across differing measurement techniques demonstrates the broad applicability of the suggested parameter spaces. Recommendations for qualifying measurements acquired using different instruments, not explored in this work, will be provided. This will allow community-wide comparison of area-based surface topographical measurements, beyond the linear measurement standards suggested in ISO 21920-3-2021.
