- In the automotive industry, the measurement, control and reproducibility of certain morphological characteristics of surfaces are increasingly required since the surface morphology may be able to explain a large number of physical and mechanical characteristics, such as the degree of wear or the degree of adhesion by adhesives, glues or paints on the surfaces themselves. In this regard, the work is based on the study of ISO-25178 surface morphological parameters capable of completely characterizing a polymeric surface from a microstructure point of view. In particular, this work studies different surfaces in Abs (Acrylonitrile butadiene styrene) and PC-Abs (Polycarbonate/acrylonitrile butadiene styrene) material after different etching treatments performed with different chemical elements: these treatments can radically modify the micro-roughness of a surface making it more or less suitable according to the industrial purposes sought. In addition, the work wants to identify which set of ISO-25178 morphological parameters can be used to catalog the micro-roughness of surfaces depending on the chemical treatment applied and the type of industrial application. This study is therefore based on the use of a confocal optical microscope and a Scanning electron microscope (SEM), which allow to obtain surface morphological information on a micrometric and nanometric scale. These results are analyzed with special imaging and three-dimensional scanning software that allow not only the precise measurement of morphological parameters, but also the application of different filters that make the measurements more reliable and allow a broader analysis.
