Abstract

A method for preparing a titanium nitride-titanium diboride-cubic boron nitride composite material is disclosed. Titanium powder and cubic boron nitride raw powders are mixed by a planetary ball milling method, and then the titanium nitride-titanium diboride-cubic boron nitride composite material is prepared through the steps of wet mixing, drying, sieving, pre-sintering through a high-temperature vacuum furnace, cold isostatic press molding and high-temperature sintering.
