An abrasive body containing diamond as the abrasive is characterized in that the surfaces of the diamond particles are coated with molybdenum and the coated particles are connected by a copper matrix. The diamond may constitute at least 50% of the volume of the body. The body may be made by coating the diamond particles with molybdenum by the glow discharge method, coating the molybdenum-coated particles with copper, and compacting the doubly coated particles under heat and pressure. The compact may then be incorporated into an abrasive tool.ALSO:An abrasive body is prepared by coating diamond particles with molybdenum, for example by the glow-discharge method, then coating the molybdenum-coated particles with copper, and compacting the doubly-coated particles under heat and pressure. The glow-discharge method of 1,100,447 may be used. The resultant compact may contain at least 50% by volume diamond particles. |
