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.

The invention relates to a method of producing a flat slide valve with incorporation of at least one inlet disk in a housing or in at least one element of a housing, wherein the inlet disk is joined to the housing or to at least one element of the housing by forcelocking, formlocking and/or bonding. The invention further provides a flat slide valve having at least one sealing disk, in which at least one of the sealing disks is incorporated into an element of the flat slide valve.

The invention relates to a composite body in which a ceramic component and a metal component are bonded to one another by internal soldering. The internal soldering is effected with soldering composition in a recess (2) within a component (1) of the one material in which there is arranged a component (3) of the other material which is shaped to fit accurately. The recess (2) is, at at least one end-face opening, surrounded by a chamfer (5) having an angle .phi. smaller than 35.degree. C., while the wetting angle .beta. between the soldering composition and the plane of the component surface in which the recess is located is smaller than 40.degree..
