Friction welding non-metallics to metallics

摘要

A method of inertial bonding of a conductive metallic member to a fragile non-conductive member, comprising: (a) depositing a thin adherent conductive pad (11) onto the fragile member (10) to present a first friction creating surface (12) ; (b) forming the conductive metallic member (13) with a second friction mating surface (14) conforming essentially to the first friction creating surface (12); (c) bringing the first and second friction surfaces (12,14) together with high relative movement transverse to the surfaces and with a gradually increasing forging force along an axis perpendicular to the surfaces to generate sufficient frictional heat therebetween to effect at least a galling or smearing of melted particles of said surfaces; and (d) abruptly ceasing the relative rotation and increasing forging force upon the attainment of such melted particles at the engaging interface between the surfaces (12,14). The invention also discloses an automotive body glass product, and an aluminium clip useful for being bonded to glass and serving as a terminal for an electrical lead circuit in or on such glass.
