Detection of one or more interstitial constituents in a polycrystalline diamond element by neutron radiographic imaging
First Claim
1. A method of non-destructively testing a polycrystalline diamond element, comprising:
- providing an at least partially leached polycrystalline diamond element including a plurality of bonded diamond grains defining a plurality of interstitial regions, at least a portion of the plurality of interstitial regions including one or more interstitial constituents comprising at least one leaching by-product disposed therein;
exposing the at least partially leached polycrystalline diamond element to neutron radiation from a neutron radiation source;
receiving a portion of the neutron radiation that passes through the at least partially leached polycrystalline diamond element; and
determining at least one characteristic of the at least partially leached polycrystalline diamond element at least partially based on the portion of the neutron radiation received, the at least one characteristic including a presence of the at least one leaching by-product.

Abstract
In an embodiment, a method of non-destructively testing a polycrystalline diamond (“PCD”) element includes providing a PCD element including a plurality of bonded diamond grains defining a plurality of interstitial regions, at least a portion of the plurality of interstitial regions including one or more interstitial constituents disposed therein. The method further includes exposing the PCD element to neutron radiation from a neutron radiation source, receiving a portion of the neutron radiation that passes through the PCD element, and determining at least one characteristic of the PCD element at least partially based on the portion of the neutron radiation received. For example, the at least one characteristic may be the presence and distribution of metal-solvent catalyst, residual metal-solvent catalyst, an infiltrant, residual infiltrant, or other interstitial constituents within a PCD element.

-
providing an at least partially leached polycrystalline diamond element including a plurality of bonded diamond grains defining a plurality of interstitial regions, at least a portion of the plurality of interstitial regions including one or more interstitial constituents disposed therein; and exposing the at least partially leached polycrystalline diamond element to neutron radiation from a neutron radiation source; receiving a portion of the neutron radiation that passes through the at least partially leached polycrystalline diamond element; and at least partially based on the portion of the neutron radiation received, determining a presence of one or more interstitial constituents including at least one leaching by-product within a portion of the interstitial regions of the at least partially leached polycrystalline diamond element; and correlating the determined presence of the at least one leaching by-product within the portion of the interstitial regions with at least one performance characteristic of the at least partially leached polycrystalline diamond table. - View Dependent Claims (20)
