Abstract

Ceramic cutting tool material has a matrix of silicon nitride or alumina in which is dispersed up to 35 wt.% of monocrystalline whiskers. The reinforcement includes at least 5% of each of two at least of the following: (a) fibres with dia. less than 1 micron and an aspect ratio of 15-150; (b) fibres with a dia. of 1-6 microns and an aspect ratio of 5-100; (c) discs with an equivalent dia. of 5-50 microns and an aspect ratio of 5-50. Pref. the whiskers are of silicon carbdie. An alumina matrix pref. contains 3-20 wt.% of zirconia and optionally 1-20 wt.% of chromium as Cr2O3. A silicon nitride matrix pref. contains up to 10% of zirconia.
