摘要：
A method for forming a thermally stable cutting element that includes forming at least one acid infusion pathway in a polycrystalline abrasive body containing a catalyzing material to be leached; and contacting at least a portion of the at least one acid infusion pathway in the polycrystalline abrasive body with a leaching agent is disclosed.
