Abstract:

A process for producing a diamond composite comprising diamond powder particles bonded together by polycrystalline diamond by 1 pressing an intimate mixture of fine opaque nondiamond carbon powder and transparent diamond powder to form a green body that is confined in either a thin walled transparent quartz vessel or a polycrystalline diamond coating 2 using a pulse laser to quickly melt the opaque nondiamond carbon powder, and 3 allowing the carbon melt to cool and grow homoepitaxially from the surfaces of the diamond particles producing a polycrystalline diamond that bonds the diamond particles together.
