Abstract
The present invention relates to whisker reinforced ceramic bodies with new and improved properties. By replacing the tool pressing with injection molding, surprisingly a more homogeneous structure and more advantageous whisker orientation has been obtained. By choosing the conditions of the molding, it is possible to control the whisker orientation to get optimal material properties. Bodies according to the invention are particularly suitable for chip forming machining of heat resistant materials.
Claims7
A ceramic body cutting tool insert comprising 10-40 volume % single crystal whiskers homogeneously and essentially unidirectionally disposed in a ceramic matrix.
