PCD/PDC Specialized Diamond

Tianjian’s Advantages in Addressing Four Major Industry Challenges: 

Crystal Structure Orientation Control – Enhances Resistance to Chipping and Extends Service Life 

High proportion of isometric crystals with excellent crystal face integrity. Reduces stress concentration points caused by irregular grains. 

Nanoscale Surface Activation – Strengthens Interfacial Bonding

Proprietary powder surface treatment enhances bonding with metal matrices.Reduces the risk of delamination between the PCD layer and carbide substrate, improving impact toughness of the composite cutter. 

High-Purity System – Suppresses High-Temperature Graphitization

High purity with no magnetic impurities and low non-metallic impurity content. Effectively inhibits the conversion of diamond to graphite under sintering conditions.
