The main characteristics of the hardfacing of the stabilizer include excellent wear resistance, high hardness, good impact resistance, and H2S corrosion resistance. The hardness of its weld overlay is generally between HRC57-62, ensuring good wear resistance and impact resistance
In addition, the hardfacing of the stabilizer is usually made of Cr Mn Mo alloy system, which can provide uniform and stable weld hardness, ensuring that the drill pipe joint and casing are protected simultaneously during the drilling process

2. Manufacturing process and application scenarios of hardfacings
The manufacturing process of hardfacings for stabilizers includes technologies such as plasma spray welding and laser cladding. Plasma spray welding adopts the plasma cladding spray welding process, in which the powder is welded to the surface of the stabilizer through deposition, achieving metallurgical bonding. The weld layer has good bonding strength with the base material and is not easily detached. Laser cladding uses a laser beam to fuse the cladding material onto the surface of the substrate, forming a surface coating with specific functions.
3. The application effect and advantages of hardfacings
The application effect of the hardfacing of the stabilizer is significant, which can reduce the severe radial and axial vibration wear of the elastic system of the drill string in the hole, reduce the eccentric wear of the drill bit and drill rod, extend the service life of the stabilizer, and reduce the cost of use
In addition, the use of hardfacings can also improve the efficiency and safety of drilling operations
