Abstract

The paper provides the reasoning behind the choice of an iodine-transport method for vapor phase deposition of a Ti-compounds’ layer with uniform thickness on the surface of cubic boron nitride powder grains, to be used as a precursor for subsequent formation of a nitrideboride binder phase for the final composite material, which is promising candidate for thermally stable, high-hardness cutting tools, resistant to impacts and corrosion. The process of plating cubic boron nitride (CBN) powder with titanium compounds via vapor phase transport method was studied experimentally. The paper presents the results of microstructure imaging and XRD analysis of phase composition of the processed powders.
