Abstract:
A process for adhesively bonding a metal adherend to a second adherend, the process comprising:a) providing a first metal adherend and a second adherend, each having a respective surface to be joined to the other respective surface;b) providing a laser beam;c) directing the laser beam to the metal adherend surface for a time and intensity sufficient to effectuate ablation of any organic and halogenated residues present on the surface, to glaze said surface, to form a substantially stable metal oxide layer thereon, and to microtexturize said surface such that a roughened surface is formed; andd) applying an adhesive to the one roughened surface and placing the one roughened surface against the second adherend such that the adhesive bonds the metal and second adherends to each other along their respective surfaces.
