摘要:
The invention relates to the field of material sciences and concerns a metal-ceramic composite with good adhesion, as can be used for example for forming tools or cutting tools. The object of the present invention is to provide a metal-ceramic composite with good adhesion which has a solid and durable bond between the ceramic and the metal. The object is achieved by a metal-ceramic composite with good adhesion comprising a metal component and a ceramic component which are joined together by material connection or material connection and frictional connection, wherein silicon, beryllium, titanium, chromium, nickel, manganese, hafnium, vanadium, zirconium, aluminium and/or their organic compounds are present in the region of the connecting surfaces and wherein the components have been made into a composite and together sintered as a green body. The object is also achieved by a method in which at least one metal component and one ceramic component are joined as an overall green body and together subjected to a temperature treatment, at least for the sintering of the ceramic components.
