Abstract
A method of inertial bonding of a conductive metallic member to a fragile non-conductive member, comprising: (a) depositing a thin adherent conductive pad onto the fragile member to present a first friction creating surface: (b) forming the conductive metallic member with a second friction mating surface conforming essentially to the first friction creating surface; (c) bringing the first and second friction surfaces 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.
