In the automotive industry, the measurement, control and reproducibility of certain morphological characteristics of surfaces are important to characterize, qualify, certify and optimize different physical properties, such as the degree of wear, the degree of adhesion by adhesives, glues or paints and optical properties. In this regard, this work is intended demonstrate how it is possible to characterize different surfaces in ABS (Acrylonitrile Butadiene Styrene) and PC-ABS (PolyCarbonate/Acrylonitrile Butadiene Styrene) through a set of morphological parameters defined according to the ISO 25178 standard. These surfaces have been subjected to different etching treatments performed with different chemicals, which can radically modify the morphology of the surface, making it more or less suitable according to the industrial purposes sought. Furthermore, in this work an analytical relationship between the hybrid parameters Sdq and Sdr defined in the ISO-25718 standard is also proposed, valid for many surfaces of general use. This study is based on the use of a confocal optical microscope and a SEM (Scanning Electron Microscope), which allow surface morphology to be studied at the micro/nano scale and the measurements are analyzed with special imaging and three-dimensional scanning software that allows the precise measurement of morphological parameters of the standard ISO-25178.

汽车工业用 ABS 和 PC-ABS 表面的形态表征

在汽车工业中，表面的某些形态特征的测量、控制和再现性对于表征、鉴定、认证和优化不同的物理特性非常重要，例如磨损程度、粘合剂、胶水或油漆的粘附程度以及光学特性。在这方面，这项工作旨在展示如何通过根据 ISO 25178 标准定义的一组形态参数来表征 ABS（丙烯腈丁二烯苯乙烯）和 PC-ABS（聚碳酸酯/丙烯腈丁二烯苯乙烯）中的不同表面。这些表面已经用不同的化学物质进行了不同的蚀刻处理，这可以从根本上改变表面的形态，使其或多或少适合所寻求的工业目的。此外，在这项工作中，还提出了 ISO-25718 标准中定义的混合参数 Sdq 和 Sdr 之间的分析关系，适用于许多通用表面。这项研究基于使用共焦光学显微镜和 SEM（扫描电子显微镜），可以在微/纳米尺度上研究表面形态，并使用特殊的成像和 3D 扫描软件分析测量结果，该软件允许符合 ISO-25178 标准的形态参数的精确测量。
