Method for Producing a Component

The method for manufacturing a composite material consisting of a metal and/or a metal alloy and particles of highly heat-conducting material, comprising diamond and/or cubic boron nitride, the method comprising:

• a) applying a layer section having predetermined dimensions of the composite material of the metal and/or the metal alloy and the particles of a highly heat-conducting material, comprising diamond and/or cubic boron nitride, in a predetermined area on a base layer by melting the metal or the metal alloy by a heat source in such a way that the metal and/or metal alloy forms, within the predetermined dimensions, a cohesive matrix in which particles of the highly heat-conducting material are embedded, and then cooling, wherein the metal, unless it is an ingredient of the metal alloy, is not selected from the alkali metals and calcium, strontium, barium or radium, wherein the application of a layer section to the base layer involves one of the following steps 1) through 4)
• 1) supplying a powder bed of a mixture of powdered metal and/or metal alloy particles and particles of the highly heat-conducting material, comprising diamond and/or cubic boron nitride, and/or a mechanical alloy of the metal and/or metal alloy and particles of the highly heat-conducting material on the base layer and melting the metal and/or metal alloy in subarea of the powder bed having predetermined dimensions by means of a heat source, in such a way that the metal and/or metal alloy forms, within the predetermined dimensions, a cohesive matrix in which particles of the highly heat-conducting material are embedded, and then cooling;
• 2) supplying powdered metal and/or metal alloy particles and particles of the highly heat-conducting material, comprising diamond and/or cubic boron nitride and/or a powdered mechanical alloy of the metal and/or metal alloy and particles of the highly heat-conducting material by one or more nozzles onto a predetermined area of the substrate and melting the metal and/or metal alloy by means of a heat source in such a way that the metal and/or metal alloy forms, within the predetermined dimensions, a cohesive matrix in which particles of the highly heat-conducting material are embedded, and then cooling;
• 3) applying a heat source to one end of a hollow metal and/or metal alloy wire or tube in whose cavity particles of the highly heat-conducting material, comprising diamond and/or cubic boron nitride and/or the mechanical alloy of the metal and/or metal alloy and particles of the highly heat-conducting material are arranged in such a way that the portion of the metal and/or metal alloy wire or tube on which the heat source acts is melted and forms, within a predetermined area, a cohesive matrix in which particles of the highly heat-conducting material are embedded, and then cooling;
• and
• 4) supplying a powder bed of powdered particles of the highly heat-conducting material, comprising diamond and/or cubic boron nitride, and of a wire or rod of the metal or the metal alloy, applying a heat source to one end of the wire or rod in such a way that the portion of the wire or rod on which the heat source acts is melted and, as a melt, infiltrates a predetermined section of the powder bed of the highly heat-conducting material and surrounds its particles in the form of a cohesive matrix, and then cooling;
• and
• wherein the base layer that does not consist of the composite material is subsequently separated so that in the case in which the highly heat-conducting material does not comprise cubic boron nitride, at least one additional layer section of composite material is applied to a base layer comprising the layer section of composite material applied previously.

A composite material of a metal and/or a metal alloy and particles of a highly heat-conducting material, comprising diamond and/or cubic boron nitride, that can be manufactured by a method comprising:
