Abstract

The invention discloses a method for detecting cobalt removal depth of a polycrystalline diamond compact. The method comprises the following steps: pretreatment is carried out for the polycrystalline diamond compact with cobalt removed; the polycrystalline diamond compact is cut at a diameter direction along a cross section; further processing is carried out for a section of the polycrystalline diamond compact; scanning and screenshot are carried out for the section, and the cobalt removal depth is marked. The method for detecting cobalt removal depth of the polycrystalline diamond compact has a simplified flow for preparing a sample, so that detection cost is substantially reduced.

Description

technical field [0001] The invention belongs to the technical field of superhard tool manufacturing, in particular to a method for detecting the cobalt removal depth of a polycrystalline diamond composite sheet. Background technique [0002] With the wide application of diamond compacts in the fields of oil and natural gas extraction and the continuous improvement of oil and gas extraction technology, the demand for high wear-resistant diamond compacts is also increasing. The cobalt removal operation on the diamond composite sheet can effectively improve the heat resistance of the product, thereby greatly improving the wear resistance of the diamond composite sheet product. [0003] At present, the methods used to remove cobalt from polycrystalline diamond compacts mainly include electrolysis and acid leaching. Although the principles are different, they can effectively remove part of the cobalt in the diamond layer and effectively improve the heat resistance of diamond comp...
