A method for producing a ceramic composite work material, ceramic composite material and from this existing ceramic sintered body

摘要

The invention relates to a process for producing a ceramic composite material of the workpiece, wherein the ceramic composite material as a silicon carbide - titanium diboride - composite material is present, comprising the following process steps:a) mixing a first solid fraction of a sinterable silicon carbide - a mixture with a second solids content of titanium carbide to a mixture of substances, wherein the two components be present as a powder, and wherein the amount of silicon carbide solid fraction at least 55 w -% and the amount of titanium carbide solid fraction amount to a maximum of 30 w -%,b) adding a boron-containing additive, wherein the boron-containing additive of boron or boron carbide, wherein the solids content of the boron-containing additive in relation to the solids content of the titanium carbide at least 36 w -% is, if the boron-containing additive as boron is present or at least 46 w -% is, if the boron-containing additive is present as boron carbide.c) sintering of the compound, wherein the sintering being carried out at atmospheric pressure and by a reaction of the titanium carbide with the boron-containing additive of titanium diboride and carbon are formed and wherein the formation of the titanium diboride takes place in - situ.Furthermore, the invention relates to a ceramic composite material as well as a ceramic sintered body.
