Abstract
The present disclosure relates to polycrystalline diamond covalently bonded to a substrate by spark plasma sintering and methods of covalently bonding polycrystalline diamond and a substrate. Spark plasma sintering produces plasma from a reactant gas found in the pores in the polycrystalline diamond and, optionally, also the substrate. The plasma forms carbide structures in the pores, which covalently bond to the substrate.
