Abstract
The invention relates to composite materials based on tungsten carbide and comprising gold, palladium and/or platinum and to a method for producing said composite materials by sintering. By means of the FAST method, hard and biocompatible WC/(Au, Pd, Pt) composite materials can be produced, inter alia for use as coatings on tools and prostheses and as solid bodies in, for example, blood pumps.
