Abstract:

A process for bonding two diamond surfaces together by 1 forming a layer of opaque non-diamond carbon material between the two diamond surfaces 2 pressing the diamond surfaces together with the opaque non-diamond material sandwiched between the diamond surfaces 3 used pulse lased light to quickly melt all the opaque non-diamond carbon material before a significant amount of heat is lost through the diamond surface and then 4 allowing the resulting carbon melt to cool and solidify as polycrystalline diamond which grows homoepitaxially from the diamond surfaces, bonding those surfaces together.
