Abstract
A front face of a diamond table mounted to a substrate is processed to introduce a material which comingles with or semi-alloys with or partially displaces interstitial catalyst binder in a thermal channel to a desired depth. The material is selected to be less thermally expandable than the catalyst binder and/or more thermally conductive than the catalyst binder and/or having a lower heat capacity than the catalyst binder.
