The influence of metal pretreating on the properties of adhesively bonded j
oints was investigated. AlMg3 and several pre-treatment methods were used.
The pre-treated surfaces and the joints were characterized using: SEM/EDX,
XPS, EIS, surface tension, DMA mu TA and the determination of mechanical pa
rameters. The highest bond strengths were obtained using anodic oxidation i
n phosphoric acid as the pre-treatment method.
