ABSTRACT:
Multigrain abrasive particles and articles made therefrom are provided wherein the particles comprise fine granules of cubic boron nitride or diamond bound by a sintered matrix of one or more layers of active coating material that is chemically bonded to the underlying surface. These particles are obtained by sintering the coated granules under relatively mild conditions in comparison to those necessary to form monocrystalline abrasive particles of a similar size. In certain embodiments, the use of high pressure, high temperature equipment can be avoided. The particles have improved breakdown characteristics which can be controlled through a selection of the coating thickness, the type of coating and the size of the fine granules to be bonded. The process is well suited for the use of diamond powder produced from chemical vapor deposition processes.
