ABSTRACT:
The method of adhering a preformed continuous film of fluorcarbon plastic material to a flat or convex metal surface which comprises heating both the metal surface and a layer of the plastic material superposed upon the metal surface in a gaseous environment of reduce pressure sufficiently to soften the plastic film and bond the same to the metal surface employing multiple steps of heating, bonding and cooling without application of increased pressure to the outer surface of the heated plasttic film to form a bonded metal-plastic combination without entrapment of gas. The invention is particularly adapted to the bonding of fluorocarbon plastic material to surfaces of metal such as aluminum, iron, iron alloys, copper, and copper alloys.
