Molded Bodies Having a High Degree of Hardness and a High Degree of Toughness for Machining Metals, Carbides, Ceramics and Glasses.

摘要

This paper is a European patent application for molded bodies having a degree of hardness and a high degree of toughness for machining metals, carbides, ceramics and glasses. The invention concerns molded bodies having a high degree of hardness and a high degree of toughness for machining metals, carbides, ceramics and glasses, made of sintered boron carbide and a binding metal phase. The goal of the invention is to introduce bodies of this type in which strength, especially toughness, is higher than in molded bodies of pure B4C and which are very well suited for cutting or grinding tools or for applications in which mechanical wear stresses or high surface pressures must be faced, such as in nozzles.
