Method and system for perceiving a boundary between a first region and a second region of a superabrasive volume

摘要

Methods of evaluating a superabrasive volume or a superabrasive compact are disclosed. One method may comprise exposing a superabrasive volume to beta particles and detecting a quantity of scattered beta particles. Further, a boundary may be perceived between a first region and a second region of the superabrasive volume in response to detecting the quantity of scattered beta particles. In another embodiment, a boundary between a catalyst-containing region and a catalyst-diminished region of a polycrystalline diamond volume may be perceived. In a further embodiment, a boundary may be perceived between a catalyst-containing region and a catalyst-diminished region of a polycrystalline diamond compact. Additionally, a depth to which a catalyst-diminished region extends within a polycrystalline diamond volume of a polycrystalline diamond compact may be measured in response to detecting a quantity of scattered beta particles. A system configured to evaluate a superabrasive volume is disclosed.

1. A system for evaluating a superabrasive volume, the system comprising:
a radiation source configured to direct radiation toward a superabrasive volume, wherein the superabrasive volume is bonded to a substrate; a radiation detector for detecting radiation that interacts with the superabrasive volume; calibration data for correlating a characteristic of the detected radiation to an indicated depth of a first region of a coherent matrix of a superabrasive volume, the indicated depth being less than a total thickness of the coherent matrix.
