CUBIC BORON NITRIDE COMPACT

摘要

A method of making polycrystalline CBN compacts, high in CBN content, is provided. The method includes making a powdered composition by subjecting a mixture of CBN, present in an amount of at least 80 volume percent of the mixture, and a powdered binder phase to attrition milling. This powdered mixture is subjected to conditions of elevated temperature and pressure suitable to produce CBN compacts.
