Composite disk

Abstract

The invention relates to a composite disk for use as inlet or regulating disk, wherein a support disk and at least one hard material disk having a functional surface are arranged above one another, the support and hard material disks are joined to one another by frictional fastening, forcelocking, formlocking, mechanical interlocking, retention by self substance and/or bonding, the support disk has a thickness of at least 0.6 mm and the hard material disk has a thickness of from 0.05 to 2.5 mm and the hard material disk comprises a material having a Vickers microhardness of at least 1300 HV 0.5. The invention further provides a method of producing a composite disk, which comprises arranging a support disk and at least one hard material disk having a functional surface above one another with the disks having adjacent faces and joining the support disk by frictional fastening, forcelocking, formlocking, mechanical interlocking and/or bonding to the hard material disk by means of adhesive bonding, mechanical intermeshing and/or placing together of rough adjacent faces.
