“…In order to overcome the limitations of traditional probe-based methods, laser microscopy has emerged as a valuable tool for non-contact measurement of surface geometry, offering the ability to extend the assessment of surface roughness to two or three dimensions. [33][34][35][36][37][38][39][40][41][42] By employing laser microscopy, it becomes possible to introduce surface parameters that go beyond linear roughness factors and provide a comprehensive understanding of the interface condition based on etching conditions. Two such parameters, the arithmetic average roughness of the unit area (S a ) and the developed surface area ratio (S dr ), which represents the increment of surface area relative to the flat x-y plane, can be utilized to quantify the interface condition.…”

The peel‐off strength of the electroplated specimens exhibits corresponding increase, particularly pronounced in ABS‐rich blends. However, it is observed that the interface displays incomplete contact between the metal and polymer. We suggest a new parameter, the Sdr ratio (Sdr,polymer/Sdr,plating), which provides the prediction of the adhesion strength of the physically interlocked metal‐polymer interface. The change in Sdr ratio effectively reflects the change of peel‐off strength, which is more efficient for phases with increasing ABS content. By examining the relationship between surface morphology and adhesion strength, our research provides the insights into optimizing the adhesion properties of electroplated metal‐polymer interfaces for PC/ABS blend.

Additive manufacturing in combination with adhesive bonding enables high lightweight potential in structural design. A decisive factor for high adhesive bond performance are the surface properties. In the present work, the surface morphology of laser powder bed fusion (PBF-LB) processed Ti6Al4V parts was investigated in the as-built condition for the build orientations 0°, 45°, 90°. Furthermore, subsequent surface treatment by grit blasting or laser treatment allowed to modify the surface morphology and examine its effect on the bond strength. The surface characteristics were assessed using scanning electron microscopy, laser confocal microscopy and contact angle measurements. Evaluating the bond strength was done for tensile loading by centrifugal adhesion testing. The lowest bond strength was found for 0° oriented specimens, while the 45° and 90° oriented samples showed similar strengths. Fracture surface analysis of the as-built surfaces showed that the partially melted particles remain attached and cause mechanical interlocking. Furthermore, surface treatment by grit blasting allowed a minor improvement of the bond strength, while with laser treatment a significant increase was possible.
