JCB PDC coal mine composite sheet is sintered from diamond micropowder and cemented carbide substrate under ultra-high temperature and high pressure conditions. JCB PDC coal mine composite sheet has high wear ratio and impact resistance. At the same time, it improves the bonding mode between diamond layer and cemented carbide interface, improves stress distribution, and makes the bonding surface more solid. It greatly improves the reliability and service life of the product, and has a high cost performance. JCB PDC coal mining composite sheet is widely used in geological exploration, coal drilling, mining drilling, foundation drilling and so on. JCB can provide 08, 09, 10, 13, 16, 19 and other general specifications and various custom specifications of PDC composite products.
The PDC coal mine composite sheet produced by our company uses high-quality diamond micropowder as raw material and sintered the diamond micropowder and cemented carbide substrate under ultra-high temperature and high pressure conditions. The product has the characteristics of high wear ratio, impact resistance, fast penetration, high efficiency, and economical benefits. At the same time, the combination of diamond layer and cemented carbide interface is improved. It improves the stress distribution, makes the bonding surface more firm, greatly improves the reliability and service life of the product, and has a high cost performance. Widely used in geological exploration, coal field drilling, mining drilling, foundation drilling and so on. Company can provide 08, 09, 10, 13, 16, 19 and other general specifications and various custom specifications of PDC composite products.
