Adhesion strength of adhesive bonded NiTi thin metal sheets

Published: July 10, 2013, 7:33 a.m.

The present work is focused on the analysis of adhesive bonded shape memory NiTi thin metal sheets. To this aim different surface preparation techniques have been employed, i.e. degreasing, grit blasting and chemical etching, and their influence has been assessed by analyzing the variation of surface roughness and surface energy. After that, adhesive bonded single lap NiTi/epoxy joints have been prepared and tested and the mechanism of failure has been monitored in situ by using a CCD camera.
