In this work, aluminum alloy AA6061-T6 with a thickness of 1.5 mm is lap-joined with a polymer, High-Density Polyethylene (HDPE) with 4 mm using the friction lap joining (FLJ) technique. To increase the pore size, the aluminum alloy surface area underwent the anodizing process. The effects of joining factors such as transverse speed (50, 70, 90, and 160 mm/min) and rotational tool speed (920 and 1500 rpm) were examined. Tensile shear, Scanning Electron Microscopy (SEM), and the X-Ray Diffraction test (XRD) were all performed on each specimen. Two different failure types were noted; the first involved the lap joint (shear), while the second involved the side polymer. According to the most recent failure, the anodized process produced a good pore size where the melted polymer could pass through it. This suggests that the transverse and rotating speed processing factors impact joint efficiency. The highest joint performance is at 1500 rpm and 70 mm/min. The outcomes of the design of experiments are analyzed using the Minitab application. The shear force for joints was shown to be most affected by transverse speed. In the re-solidification zone, the interaction between aluminum and polymer is clearly visible. According to the SEM test, the bonding zone has a depth of roughly 17 µm. Additionally, the analysis's findings showed that for the Al/HDPE joint, this layer was primarily made of oxygen and aluminum. Aluminum and AL2O3 make up most of the phases, according to the XRD study. [ABSTRACT FROM AUTHOR] |
