Abstract
A method for bonding plastic to a metallic member is described which comprises the steps of forming a preselected pattern of etched cavities in the metallic surface to be bonded, which cavities at least in part increase in width with depth of etching, and subsequently applying a plastic layer to the metallic surface so that a portion of the applied plastic layer fills the cavities and form an interlock with the metallic surface.
