Method and system for perceiving a boundary between a first region and 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 radiation and detecting a response of the radiation when it interacts with the superabrasive volume. In one embodiment, a boundary may be perceived between a first region and a second region of the superabrasive volume in response to detecting the response of the radiation. In one particular embodiment, a boundary between a catalyst-containing region and a catalyst-diminished region of a polycrystalline diamond volume may be perceived. Additionally, a depth to which a catalyst-diminished region extends within a polycrystalline diamond volume of a polycrystalline diamond compact may be measured based on the monitored response of the radiation. In a further embodiment, a non-planar boundary between the two regions may be mapped. A system configured to evaluate a superabrasive volume is also disclosed.
