“…The peeling forces in Figure 7 prove that the deeper polymer regions have a higher fracture toughness than the surficial polymeric layer. This is empirical evidence that the phenomenon of "overreaching" is not only owing to the unfilled voids, as previously thought [35] but also owing to the degraded polymer integrity. The peeling force can be increased by guiding the crack deeper from the etched surface.…”

“…This weakens the surface and eventually reduces the peeling force necessary to delaminate the metallic coating from the polymeric part. Furthermore, Seo et al [35] showed inner voids at the interface after over-etching, which act as stress concentrators and crack nucleation spots during coating delamination. In summary, the aggressive etching of ABS polymer ensures the interlocking geometry, but it can also degrade the polymer strength.…”

“…Seo et al suggested the peeling mechanism of electroplated ABS, in which some voids were generated at the interface between substrate and electroplated metal layer with increasing etching time. 43 They found that the incomplete interface was generated if the etched substrate became more complex and deeper because the immersion of electrolyte containing metal ions became harder.…”

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.

“…Some research results have indicated that, with the increase of metal surface roughness, the mechanical interlock performance and physical adsorption activity would increase, resulting in the increase of bonding strength between polymer and metal. [40][41][42] Moreover, The relatively large substrate surface roughness would cause the interface defects and interface stress concentration easily, weakening the bonding strength in some regions between plating and substrate. 43,44 When the relatively large peeling force is applied on the polymer coated steel, the plating in some regions with poor bonding strength would fall off from the substrate (just as shown in Figure 7(a) and (b)).…”

The effect of surface roughness of electroplating chromium coated steel on bonding strength of polymer coated steel has been investigated in this paper. The experimental results have shown that the electroplating chromium coated steel with different surface roughness could be obtained through the substrate surface treatment before the electroplating process. The peeling test results have shown that the peeling force of the polymer coated steel would increase with the increase of surface roughness of the electroplating chromium coated steel, but the increase rate would become slow gradually. With the increase of surface roughness of electroplating chromium coated steel, the PET film would be damaged locally and some polymer residues would remain on the electroplating chromium coated steel; when the bonding force is large enough, the plating shedding would occur on the electroplating chromium coated steel. With the appearance of the polymer residues and the occurrence of plating shedding, the failure mode of polymer coated steel would transform from adhesion failure mode to the mixed failure mode.
