Abstract
A method for increasing the wear-resistance of a work piece involves connecting the work piece to a non-formable core material having a greater hardness than that of the work piece material. In order to improve the connection while simultaneously reducing the costs, the core material is connected in a form-fitting manner to the work piece by means of cold extrusion or hot extrusion of the work piece material.
Claims7
A method for increasing the wear-resistance of a work piece, comprising connecting the work piece to a core material that cannot be reshaped and which is of a greater hardness than the work-piece material in a form-fitting manner by means of cold-extrusion or hot-extrusion of the work-piece material, wherein the core material comprises ceramic material and has additional shaped elements provided on a peripheral surface of the core material for securing the core material against torsion in the work piece after connecting the work piece to the core material.
