Characterization of metal defectIn today’s competitive environment, industrial manufacturers continue to invest heavily in tests aiming to improve metal coating performances.
In this case study, scratches on a copper surface with tin deposits were measured by a 3D optical profiler.
The roughness surface was obtained by applying filtering techniques. The surface was then partitioned into motifs with ridge lines bounding pits indicated by the + symbol. Morphological parameters and statistics on scratches obtained allowed greater understanding of scratch phenomena.
MountainsMap® tools used
Advanced filtering techniques
MountainsMap® operaters were applied to obtain the roughness surface allowing calculation of ISO 25178 Sq and Sz height parameters.
The surface was partitioned into motifs with ridge lines bounding pits indicated by the + symbol. Motifs parameters were calculated.
