The upgraded process for new petroleum drill pipes can significantly enhance performance stability
1. The new diamond drill rod undergoes vacuum quenching and tempering treatment to ensure uniform material microstructure, further enhancing corrosion and fatigue resistance while reducing the risk of failure due to material defects.
2. The tungsten carbide gradient coating achieves metallurgical bonding with the substrate through plasma cladding, ensuring surface hardness for wear resistance while reducing coating brittleness and enhancing bonding strength between the coating and substrate via gradient composition transition.
