Abstract

A process for manufacturing ceramic metal composite bodies, the ceramic metal composite bodies and their use. The process is based on molten infiltration and the simultaneous or delayed exchange reaction of ceramic or metal ceramic un-fired bodies or sintered bodies which may consist of nitrides or carbides as well as metals, with molten metal of additional metals, whereby new nitride, carbide and intermetallic phases are formed which have improved wear and high-temperature characteristics. These ceramic metal composite bodies can be used for tribological applications.
