Abstract
A well-bonded polycrystalline cubic boron nitride body is produced by providing the cubic boron nitride particles with a discontinuous coating of tungsten or molybdenum and then infiltrating them in a mass with molten silicon or silicon-base alloy.
Claims4
The bonded polycrystalline body consisting essentially of cubic boron nitride particles and a bonding medium, said bonding medium being substantially free from carbide content and consisting essentially of silicon and silicide precipitate phase, said silicide precipitate phase characterized by the presence of silicide from the group consisting of molybdenum silicide, tungsten silicide and mixtures thereof.
