Nowadays polymer-metal composites play a key role in the automotive and aerospace industry. The use of lightweight sandwich structures, for example, could lead to lower fuel consumption and decreasing CO2 emissions. In order to improve the mechanical properties of these composites, the physical interaction of the layers is of particular interest.
We have produced composite materials from galvanised steel and polyamide 6 to investigate the bonding in more detail. In order to improve adhesion, the steel surface was additionally coated with a SiOx layer using plasma-enhanced chemical solution deposition (PECSD). In further experiments, the effect of plasma-treated surfaces on the adhesion was investigated.
The adhesion behaviour was characterised by T-Peel tests and the exposed interfaces were studied with electron spectroscopy and microscopy. The spectroscopic analysis indicates different chemical bonds, due to the presence of the SiOx layer.
