ABSTRACT:
An improved method of electroforming a metallic member to a ceramic member and joint formed thereby. The method of this invention involves axially pre-loading a ceramic material to be joined to a metal shaft with a force sufficient to place the ceramic component into a state of compression about equal in magnitude to the axially directed tensile stresses expected to be induced in the ceramic material during shrinkage of the metal member about the ceramic.
Further, the compressive pre-load is applied to the ceramic member through materials suitable for absorbing shock waves which might be generated along the longitudinal axis of the ceramic material.
