Diamond Bonded Construction with Improved Braze Joint

A diamond bonded construction comprising:

• a body comprising a plurality of bonded together diamond grains with interstitial regions disposed between the diamond grains, wherein the interstitial regions are substantially free of a catalyst material used to initially form the body at high pressure/high temperature conditions, and wherein a population of the interstitial regions includes an infiltrant material disposed therein;
• a metallic substrate attached to the body;
• and
• a braze joint interposed between the body and the substrate, wherein the braze joint is formed from a braze material;
• wherein the body includes a metallic material disposed along a substrate attachment surface and in contact with the braze joint.

• a metallic substrate attached to the body;
• and
• a braze joint interposed between the body and the substrate, wherein the braze joint comprises two or more different braze material layers;
• wherein the body includes a metallic material disposed along a substrate attachment surface and in contact with the braze joint, and wherein the metallic material is different from the braze joint.

• a metallic substrate that is attached to the body;
• and
• a braze joint interposed between the body and the substrate, wherein the braze joint is formed from a braze material;
• wherein the body includes a first metallic material bonded to a substrate attachment surface, and wherein the construction includes a second metallic material that is interposed between the first metallic material and the braze joint.
