Abstract

The effect of super fine groove pattern with the width of 0.1mm and spacing of 0.2mm formed on Al alloy surface by fine machining on adhesion peel strength was investigated. The results indicate that such groove pattern can enhance adhesion strength in T-Peel test by 51.4%. A fracture model containing three stages such as fracture on Al alloy surface, inside the adhesive and along the vertical surface of the groove, is proposed and proved credible through studying the fracture morphology by scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). The fracture modes for the three stages in TPeel test are peel (interfacial + cohesive), peel (cohesive) and shear (interfacial + cohesive) respectively, which reasonably explains the enhancement mechanism of groove pattern on adhesion strength in T-Peel test.
