Joining of the dissimilar materials is necessary and important from a manufacturing viewpoint. Therefore, the authors have developed a new laser direct joining method between metals and plastics (Laser-Assisted Metal and Plastic joining method). Recently it has been reported that the LAMP joining between several metals and engineering plastics could produce sufficiently strong joints.
In this research, several LAMP joints was observed or analyzed with scanning electron microscope (SEM), transmission electron microscope (TEM), time-of-flight secondary ion mass spectrometry (TOF-SIMS) and XPS (X-ray photoelectron spectroscopy ) in order to obtain fundamental knowledge of LAMP joining structure. It was revealed that not only the anchor (mechanical bonding) effect but also chemical bonding produced by atomic diffusion were considered as bonding mechanisms of LAMP joining.
