Abstract (en)
[origin: WO2004065045A1] The invention relates to a multi-phase ceramic cutting tool with improved resistance to wear and tear on the edge area or the edge layer. Said tool is made of a ceramic base material and a sacrificial phase, and contains additives and primary hard material phases and has a long-wearing, hard, non-separated, optionally multi-layered edge area or edge layer. Said edge area consists of at least one hard substance phase. As a result of the diffusion and transposition processes, the edge area internally knits with the starting ceramic and is formed by relocating the output ceramic in a defined atmosphere.
