ABSTRACT:
A process for preparing a surface for adhesive bonding to a second surface having the steps of abrasion cleaning the surface and then applying an adhesive thereon, wherein the improvement over prior art processes comprises the displacement of atmospheric gases from the surface by means of a dry inert gas. The abrasion cleaning is preferably achieved by bombarding the surface with particulate matter and removing the particulate matter before application of adhesive to the surface. The process is suitable for preparing metal surfaces for metal to metal bonds.
