Abstract:
1. 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, the body having a top surface and a bottom surface opposite the top surface; a carbide wetting material disposed along the body bottom surface and extending therefrom at least a partial depth into the body; a braze joint disposed between the carbide wetting material and a single metallic substrate, the braze joint being formed from a braze material, wherein the braze material is different from the wetting material and is capable of forming an attachment between the substrate and wetting material at elevated temperature conditions in the absence of elevated pressure during a process independent of one used to apply the wetting material to the body.
