CHEMICALLY STRENGTHENED BOND BETWEEN THERMALLY STABLE POLYCRYSTALLINE HARD MATERIALS AND BRAZE MATERIAL
Chemical methods, optionally in combination with physical methods, may be used to increase the strength of the bond formed by a braze material between a polycrystalline material and a hard composite. Such polycrystalline materials brazed to hard composites may be found in various wellbore tools include drill bit cutters. An exemplary method may include forming a bonding layer on a bonding surface of a polycrystalline material body that comprises a hard material, the bonding surface opposing a contact surface of the polycrystalline material body, and the bonding layer substantially formed by a [111] crystal structure of the hard material, a [100] crystal structure of the hard material, or a combination thereof; and brazing the bonding layer to a hard composite using a braze material.
