摘要： A superabrasive compact and a method of making the superabrasive compact are disclosed. A superabrasive compact may comprise a diamond table and a substrate. The diamond table may be attached to the substrate. The diamond table may include bonded diamond grains defining interstitial channels. The interstitial channels may be filled with non-catalytic binder materials in some regions. The interstitial channels in some other regions may be filled with a catalytic materials from the substrate.
