摘要：
A method for facilitating infiltration of an infiltrant material into a TSP material during re-bonding of the TSP material to a substrate, by enhancing the porosity of the TSP material near the interface with the substrate is provided. Cutting elements formed by such method and downhole tools including such cutting elements are also provided.
