Abstract
The invention provides a method of altering the friability of abrasive particles particularly diamond and cubic boron nitride particles, by subjecting the particles to selected irradiation capable of producing internal defects in the particles. The irradiation is preferably a neutron flux.
Claims5
A method of decreasing the friability of diamond particles selected from SD, MD and RD diamond particles including the step of subjecting the particles to an irradiation capable of causing internal defects in the particles and consisting of an integrated flux of particles in the range 10.sup.17 to 10.sup.20 particles/cm.sup.2 or gamma irradiation.
