Method for manufacturing pcd element with infiltrant material
A recently granted patent (Publication Number: US11969860B2) discloses a method for manufacturing a PCD (polycrystalline diamond) element with specific characteristics. The method involves providing a PCD body with internal diamond surfaces containing a thermally stable porous region with unfilled pores. A mask or passivation medium is introduced to create a masked region extending into the PCD element, isolating diamond from chemical interaction with infiltrant material. The method includes steps to control temperature during the process, ensuring the proper introduction of the mask or passivation medium before infiltration occurs.
Furthermore, the method includes coating internal diamond surfaces with the mask or passivation medium, chemically isolating diamond from the infiltrant material, and introducing the mask under specific conditions. Various techniques such as atomic layer deposition, liquid pre-ceramic polymer infiltration, and vapor deposition of metal compositions are utilized. The patent also emphasizes the introduction of the infiltrant material into a significant volume of the PCD body and the creation of a barrier between the thermally stable region and the infiltrant material. Overall, the patented method offers a detailed process for manufacturing PCD elements with controlled properties and characteristics, enhancing their performance and durability in various applications.
