ABSTRACT:
Single hard particles or single point cutting tools having the particles bonded thereto are coated with a modulated or layered composition of transition metal compounds or with titanium compounds to decrease mechanical failure of the particles. Titanium and zirconium nitrides may be used to form the modulated composition. Total thickness of the coatings is in the range from about 0.5 micrometer to about 30 micrometers. Individual layers of varying composition have a thickness in the range from about 0.5 nanometers to about 30 nanometers.
